A Novel Resource Oriented DMA Framework for Internet of Medical Things Devices in 5G Network

The Internet of Medical Things (IoMT) mobile devices such as ambulance, medical done, and emergency mobile medical equipment face severe signal distortions due to interference, end-to-end packet loss, handoff delays, and lower throughputs during mobility. Network mobility basic support protocol (NBSP) has been proposed using the IP-based Wi-Fi solution to solve these issues. However, the weak signal, extra signaling overhead, and higherdelays were identified during handover due to patients' excessive requisites, resulting in radio link failure. Therefore, this article proposes a novel resource-efficient flow-enabled distributed mobility anchoring (FDMA) framework enhancing the functionalities of the centralized network entities and mobility entities.The performance of the proposed FDMA framework is evaluated and compared with the standard NBSP and proxy NEMO (PNEMO) scheme in terms of the variable number of cell residence time and mobile routers, where the proposed framework outperformed NBSP and PNEMO schemes for IoMT Mobile devices in 5G network.

RAPID-INTEGRATED NEMOV6 HANDOFF IN IEEE802.16E BWA NETWORKS

NEMO basic support protocol was created by IETF NEMO working group to extend basic end-host mobility support in, Mobile IP (MIP) protocol to provide network mobility support. However, the handover latency in this scheme is high, and not suitable for multimedia and real time applications. Many techniques have been proposed to solve this problem by parallelizing the dual layers handover and assigning the network layer handover part to the serving Mobile Router (PAR) or to the Home Agent (HA). These techniques either not fully parallelized or its advantages will be lost if the distance between the Mobile Router and its HA is so long. In this paper, we propose a new technique called Rapid-Integrated NEMO Handover (RINEMO) that keep its advantage whatever the distance between the MR and its HA and present a better parallelizing between the link layer and the network layer handover steps. Analytical results comparing the techniques are provided, showing that our technique have the lowest handover latency and lowest disruption time.

MROM Scheme to Improve Handoff Performance in Mobile Networks

Mobile Router (MR) mobility supported by Network Mobility Basic Support Protocol (NEMO BS) is a Mobile IPv6 (MIPv6) extension that supports Host Mobility. Proposed Multihoming and Route Optimization for MANEMO (MROM) scheme is designed to provide Route Optimization (RO) and Multihomed in NEMO architectures. This paper proposes two novel schemes; MANEMO routing scheme and Multihoming-based scheme. These are to provide support for next generation networks. The proposed MROM scheme differs from other schemes for NEMO environment because it considers the requirements of more application flows parameters as packet lost delivery, handoff delay as well as throughput). Another difference is that not only the network infrastructure can begin the functionality of flow routing, but also an Edge Mobile Router (EMR) can do this flow for routing. Moreover, it utilizes the state of the art and presently active access network to perform the separation of each flow in mobile network. Thus, proposed MROM exhibits multihoming features and improves handoff performance by initiating flow-based fast registration process in NEMO environment. A handoff method is proposed with enhanced functionalities of the Local Mobility Anchors (LMA), Mobile Routers (MRs) and signaling messages with a view to achieve continuous connectivity through handoff in NEMO. Both analytical and simulation approaches are used. Analytical evaluation is carried out to analyze packet delivery lost and handoff delay of our proposed scheme. It was also shown that cost of signaling messages and packet delivery are contributing to total handoff cost. At the simulation part, network simulator 3 (NS 3) has been used as the tool to get performance metrics that have been considered like packet delivery ratio, handoff delay, and packet loss. Our proposed scheme (MROM) has been benchmarking to the standard NEMO BS Protocol and P-NEMO. In this paper, we discuss proposed MROM for next generation networks, providing detailed analysis with a numerical model, proposed MROM, by maximizing the handoff performance, has been justified to have better mobility support than the ordinary NEMO BS Protocol and PNEMO.

A Packet Delivery Cost Analysis of a Flow-Enabled Proxy NEMO Scheme in a Distributed Mobility Anchoring Environment

DMM (Distributed Mobility Management) is a present elective worldview for creating a mobility management scheme to discourse the centralized issues in present IP-based mobile environments. The main reason is to enable these schemes to adapt to the present increment in the number of mobile operators, as well as mobile information traffic size, just as the pattern in the mobile Internet towards Industry 4.0 in a flat architecture. Until this point, the advancement of schemes dependent on the DMM-based method is still at fundamental phases in the Internet Engineering Task Force (IETF), as well as there is no present standard set up. With the point of taking advantage of utilizing different interfaces all at once, this paper proposes an enhanced Flow-enabled Proxy NEMO scheme in a Distributed Mobility Anchoring (FPNEMO-DMA) environment. Besides, a mathematical approach is advanced to assess the performance of the proposed FPNEMO-DMA scheme and benchmark with the existing Nemo Basic Support Protocol (NBSP) and Proxy NEMO.

Design and Evaluation of a Multihoming-Based Mobility Management Scheme to Support Inter Technology Handoff in PNEMO

Handoff management is an indispensable component in supporting network mobility. The handoff situation raises while the Mobile Router (MR) or Mobile Node (MN) crosses the different wireless communication access technologies. At the time of inter technology handoff the multiple interface based MR can accomplish multihoming features such as enhanced availability, traffic load balancing with seamless flow distribution. These multihoming topographies greatly responsible reducing network delays during inter technology handoff. This article proposes a multihoming based Mobility management in Proxy NEMO (MM-PNEMO) scheme that considers benefits of using multiple interfaces. To support the proposed scheme design a numerical framework is developed that will be used to assess the performance of the proposed MM-PNEMO scheme. The performance is evaluated in the state-of-art numerical simulation approach focusing the key success metrics of signalling cost and packet delivery cost, that eventually scaling the total handoff cost. The numerical simulation result shows that the proposed MM-PENMO delightedly reduces the average handoff cost to 60% compared to existing NEMO Basic support protocol (NEMO-BSP) and PNEMO.

An Adaptive Diffserv Approach to Support QoS in Network Mobility NEMO Environment

Network mobility basic support (NEMO BS) protocol (RFC 3963) is an extension of Mobile IPv6. The NEMO BS embraced by the IETF working group to permit any node in the portable network to be accessible to the Internet despite the fact the network itself is roaming. This protocol likewise Mobile IPv6 does not deliver any kind of Quality of Service (QoS) guarantees to its clients. It can barely offer the same level of services (i.e. Best-Effort) to all the users without obligation to the needs of applications. These propositions a challenge to real-time applications that demand a precise level of QoS pledge. The Differentiated Services have recently come to be the most widely used QoS support technology in IP networks due to its relative simplicity and scalability benefits. This paper proposes a new scheme to provide QoS to mobile network nodes within the NEMO context. The proposed scheme intends to reduce handover latency for the users of MNN as well as alleviates packet losses. The feasibility of the proposed enhancement is assessed by measuring its performance against the native NEMO BS standard protocol using the NS-2 simulator. The obtained results in the simulation study have demonstrated that the proposed scheme outperforms the standard NEMO BS protocol.

Multihoming Support in Mobile IP Networks: Progress, Challenges and Solutions

IP network mobility has already emerged as a key domain of wireless IP networking. The network research community has taken great interest and paid considerable attention to advance IP mobility applications. Accordingly, different advanced networking mechanisms have been considered to optimize IP network mobility. One of these mechanisms is network multi-homing which has been the focus of many IP mobility studies within the academic research and IETF communities. The combination of network mobility and multi-homing has turned into a conceivable approach to effectively deal with expanding system availability and improving the performance of mobile IP network. There are many studies proposed during the recent years to realize network multi-homing for the Network Mobility Basic Support (NEMO BS) protocol, a leading IETF IP mobility protocol. This paper studies and reviews up-to-date research works in supporting multi-homing for NEMO-based mobile IP networks. The aim is to investigate the current state of multi-homing support for NEMO networks and outline recent research directions in this regard.

Multipath Mobile Internet Protocol for Mobility Networks

The internet data traffic is rapidly increases by twofold or even more in the near future. Most of the data traffic are generated from mobile devices. Due to this explosion of data traffic, existing network architecture is incapable in handling such a massive data traffic. The Network Mobility Basic Support Protocol (NEMO-BSP) is an extended version of Mobile Internet Protocol (MIPv6) that is designed to support seamless communications between homogenous and heterogeneous network domains. But NEMO-BSP is suffer very high binding and tunnel cost. The Proxy Mobility Scheme Protocol (PMIPv6) was developed to overcome issues of binding and tunnel cost. There have been many attempts to reduce the binding and tunnel cost. In this research work a multipath mobile IP protocol is designed that divides data packets on multiple paths (data packers on multiple sub-flows) without tunnel formation in the mobile network environment. the Multiple Mobile Internet Protocol Scheme (MMIPS). The network is divided into domain zones called intra-domain and inter-domain zones. The proposed protocol is aimed to remove the tunnel burden and reduce the packet size which significantly reduce the binding and tunnel cost. An analytical result are show that the proposed scheme binding and packet cost is less than compared schemes.

MM-PNEMO: a mathematical model to assess handoff delay and packet loss

Wireless networks incorporate Mobile Nodes (MNs) that use wireless access networks to communicate. However, the communication among these MNs are not remained stable due to the poor network coverage during inter mobility. Moreover, the wireless nodes are typically small that results in resource-constrained. Thus, it is uphill to use algorithms having giant processing power or memory footprint. Accordingly, it is essential to check schemes consistently to evaluate the performance within the probable application scenario. To do so, numerical analysis could be a notable method to grasp the performance of mobility management schemes as well as the constraint of evolving mobility management solutions specifically for multi-interfaced MR in Proxy NEMO environment. This paper analyzes handoff performance by using a mathematical model of Multihoming-based scheme to support Mobility management in Proxy NEMO (MM-PNEMO) environment. Moreover, a comparative study has been made among the standard Network Mobility Basic Support Protocol (NEMO BSP), Proxy NEMO (PNEMO) and MM-PNEMO scheme respectively. The performance metrics estimated for these schemes are mainly handoff delay and packet loss. This paper also analysed the packet loss ratio and handoff gain as a function of cell radius, number of SMR and velocity respectively. It is apparent that, the MM-PNEMO scheme shows lower packet loss ratio (1%) compared to NEMO-BSP (11%) and P-NEMO (6%).

Performance Evaluation of Multi-Interfaced Fast Handoff Scheme for PNEMO Environment

Mobility management is classified into two parts such as location management and handoff management. The earlier one concentrates on location update whereas the later one manages continuous Internet connectivity while the Mobile Router (MR) changes its single point of attachment to the network. Therefore, frequent movement of the MR is one of the significant characteristics in Network Mobility (NEMO) environment. Because, in accordance with the standard Network Mobility Basic Support Protocol (NEMO BSP), the MR utilizes single Interface to attach to the access link. MR requires changing its Care of Address (CoA) when it moves among different wireless access networks. As a result, it can directly influence the performance of the mobility management protocols during inter technology handoff of multi-interfaced MR. This paper proposed a multi-interfaced fast handoff scheme in Proxy NEMO (PNEMO) environment. After that, it represents a comparative analysis between the proposed multi-interfaced scheme, NEMO BSP and the PNEMO scheme respectively. The performance disparities of these schemes are estimated and analyzed via both numerical and simulation approaches. The simulation is performed through NS-3 network simulator. The performance metrics estimated for evaluation are mainly handoff delay and packet loss. It has been perceived that, the proposed scheme performs better compared to the PNEMO scheme and NEMO BSP.DOI: http://dx.doi.org/10.5755/j01.eie.24.5.21848

Performance Analysis of HRO-B+ Scheme for the Nested Mobile Networks using OPNet

<p>As a demand of accessing Internet is increasing dramatically, host mobility becomes insufficient to fulfill these requirements. However, to overcome this limitation, network mobility has been introduced. One of its implementation is NEMO Basic Support protocol which is proposed by Internet Engineering Task Force (IETF). In NEMO, one or more Mobile Router(s) manages the mobility of the network in a way that its nodes would be unaware of their movement. Although, it provides several advantages, it lacks many drawbacks in term of route optimization especially when multiple nested mobile networks are formed. This paper presents a new hierarchical route optimization scheme for nested mobile networks using Advanced Binding Update List (BUL+), which is called HRO-B+. From performance evaluation, it shows that this scheme performs better in terms of throughp<em>ut, delay, response time, and traffic, and achieves optimal routing.</em></p>

Hierarchical Route Optimization Scheme Using Advanced Binding Update List (BUL+) for Nested Mobile Networks

Supporting networks that roam as one unit is needed to provide the transparency of Internet in mobile frameworks, like cars, trains, planes, buses, etc. To accomplish this, NEMO (Network Mobility) Basic Support protocol has been proposed and developed by Internet Engineering Task Force (IETF). Although, it achieves continuous, optimal and secure communication to and from all nodes, it still suffers from many drawbacks, especially when the level of nesting increases. To overcome these limitations, this paper presents a new route optimization scheme for nested mobile network using hierarchical structure with Advanced Binding Update List (BUL+). From performance evaluation, it shows that this scheme reduces packet overhead, handoff latency, packet transmission delay, and achieves optimal routing.

Network Mobility in a Locator/ID Separation Context

Internet Engineering Task Force (IETF) has proposed an extension based on Mobile IPv6 (MIPv6), named as network mobility basic support protocol (NEMO-BSP), to support NEMO in IPv6 networks. However, NEMO-BSP inherits all the drawbacks of MIPv6, such as inefficient routing path, high handover latency, and packet encapsulation overhead. To address these drawbacks of NEMO-BSP, this paper proposes an NEMO supporting scheme based on a novel Locator/ID Separation (LIDS) architecture, namely LIDS-NEMO. In LIDS-NEMO, Multiple Virtual Mapping (MVM) scheme is proposed to differentiate the intra-NEMO and inter-NEMO mobility. Besides, packets are transmitted through the most optimized route in LIDS-NEMO. The simulation results show that LIDS-NEMO reduces the signaling cost significantly when compared with NEMO-BSP and it will be a promising scheme to provide NEMO support in the LIDS context.

Novel multihoming-based flow mobility scheme for proxy NEMO environment: A numerical approach to analyse handoff performance

With Network Mobility Basic Support Protocol (NEMO BSP), each communication should pass via the home agents of all mobile routers earlier reaching their destination at the time of frequent movement among the inter-technology handoff. This eventually results in performance deterioration of the real time application scenarios conducted on mobile nodes. Accordingly, applying the multihoming technique at any place, anywhere to provide uninterrupted internet connection in NEMO is becoming a significant area for current researchers. Although multiple care-of address registration between mobile routers along with its home agents can overcome some of the multihoming issues for NEMO, one still requires a dynamic flow redirection mechanism to support mobility management in NEMO. With the intention of reducing handoff delay, a novel multihoming-based flow mobility scheme on the PMIPv6 domain in NEMO (MF-PNEMO) is proposed in this paper. In addition, the performance of the MF-PNEMO scheme is evaluated through a numerical approach. The evaluation results confirms that the MF-PNEMO scheme outperforms the standard NEMO BSP as well as fast-proxy NEMO (FPNEMO) concerning handoff delay during inter-technology handoff.

Methods/Analysis: The proposed scheme adapts the method of Fast Hierarchical Mobile IPv6 (FHMIPv6) to shrink binding locality signaling issues. Furthermore, it exploits DiffServ depiction to pull off silky delivery of real time trafficking in heterogeneous network mobility. Network Simulator (NS-2) tool version 2.28 and analytical analysis are utilized to implement and assess the performance of the proposed scheme. Findings: Network Mobility (NEMO) basic support protocol (RFC 3963) endorsed by Internet Engineering Task Force (IETF) to enlarge the maneuver of Mobile IPv6 for better unremitting Internet connectivity to the users of mobile network. Here the protocol swaps mobility task function from mobile nodes to NEMO’ router. In mobility network the router is identified as Mobile Router (MR), which executes location update with its Home Agent (HA) to launch a bi-directional tunnel between the HA and MR. NEMO is premeditated with explication so that network mobility is transparent to the nodes in order to ease location update signaling that could happen by each Mobile Network Node (MNN). Yet, delays in data delivery and higher overheads are expected to transpire because of unnecessary multiple encapsulations of data packets and sub-optimal routing. Novelty/Improvement: The proposed scheme intents to curtail the packet loss and moderate the handover latency as well.

Design and Implementation of a Multihoming-Based Scheme to Support Mobility Management in NEMO

With the worldwide deployment of different wireless access technologies and expanding requests for worldwide Internet accessibility, Network Mobility (NEMO) is turning out to be all the more requesting innovation. Therefore, NEMO Basic Support Protocol (NEMO BSP) has been anticipated by the NEMO Working Group for the continual worldwide connectivity of each node within the mobile network. Yet, NEMO BSP experiences from higher handoff delay and packet loss. Thus, fails to provide seamless handoff. This issue can be resolved by introducing multihoming concept in NEMO. The reason is to support concurrent use of multiple interfaces on a single Mobile Router. Therefore, the main objective of this paper is to propose an innovative Multihoming-based scheme to support Mobility management in Proxy NEMO (MM-PNEMO) environment. In addition, the performance is assessed utilizing simulation approach to certifying the applicability as well as the efficacy of the suggested scheme. The performance metrics used for evaluation are namely handoff delay, packet loss, packet delivery ratio, as well as throughput. The simulation is done using NS-3 network simulator. The simulation outcomes demonstrate that the proposed MM-PNEMO scheme outperforms the standard NEMO BSP and PNEMO in terms of packet loss (less than 1%) and handoff delay (average improvement by 76%).

A Numerical Evaluation on Multi-Interfaced Fast Handoff Scheme: Impact of Rising Link Switching Delay for a High Speed Car

In Network Mobility (NEMO) environment, recurrent movement of a mobile router is one of the distinguished characteristics since this may affect the performance of the existing mobility management schemes. The movement pattern straightly influence once transmission links among mobile routers are established or failed, which is connected with the system topology. Therefore, numerical evaluation is a noteworthy process to apprehend the performance of any mobility management schemes as well as the constraints of emerging mobility management outcomes specifically for mobile environments. This paper proposed a numerical model to analyze the handoff performance of the multi-interfaced fast handoff scheme during movement of mobile router among different access technology in NEMO. Afterward, using numerical model, it has presented the numerical results of multi-interfaced fast handoff scheme as well as compared it with the standard Network Mobility Basic Support Protocol (NEMO BSP) and Fast NEMO (FNEMO) scheme. Two metrics such as handoff delay as well as relative gain are considered as the performance metrics in different circumstances identified by link switching delay of the mobile router. It has been perceived from the outcomes that, the multi-interfaced fast handoff scheme performs better compared to NEMO BSP and FNEMO scheme in terms of handoff delay and relative gain.

A Numerical Framework for the Analysis of Handoff Delay Component in Proxy NEMO Environment

Network Mobility Basic Support Protocol (NEMO-BSP), the existing IETF standard for mobile network support, signifies an important portion for future heterogeneous wireless access networks. The reason is to provide continuous Internet connectivity during movement of Mobile Router (MR) in NEMO. This paper conducted a quantitative analysis on the handoff delay component of NEMO-BSP as well as its existing enhancements, i.e., Fast NEMO (F-NEMO) handoffs, and an Extension of F-NEMO (EF-NEMO), using the numerical framework. The mathematical scenario includes two access routers, one local home agent and up to 20 MRs that interrelate by two different wireless access networks are mainly WiFi and WiMAX. The analysis offers quantitative outcomes of the performance enhancements achieved via the proposed improvements concerning handoff delay gain, packet loss, and packet loss ratio. The numerical results assist in understanding the influence of link switching delay, mobility rate, and radius on the handoff delay gain, packet loss, and packet loss ratio. The results of this analysis will also be aided to pick an appropriate mobility management scheme for Proxy NEMO environment.

Handoff Performance Analysis for Multihoming-based Network Mobility Scheme

The necessity for multihoming functionality emerged since the standard Network Mobility Basic Support Protocol (NEMO BSP) acquiesces the Mobile Router (MR) to bind single Care of Address (CoA) at once with its Home Agent (HA) only. Besides, NEMO networks are usually attached through the wireless which results in less stable links. There could also be several Mobile Network Nodes (MNNs) behind the MR. Thus, a loss of Internet connectivity has higher impact compared to a single MNN. To ensure a continuous Internet connectivity to mobile networks, it is preferable to use multihoming mechanism in which MR is equipped with multiple interfaces as well as technologies. This paper has proposed a multihoming-based scheme on Proxy MIP6 (PMIPv6) domain for handoff performance analysis relating to handoff delay, packet delivery ratio, as well as throughput at different number of MR, speed and time. After that, it has developed a simulation model to assess the proposed scheme as well as compared it with Network Mobility Basic Support Protocol (NEMO BSP) and multi-interfaced scheme. Results attained from evaluation will support the network engineer to pick a suitable multihoming-based scheme in mobile environment at different number of MR, speed and time.

Secure Route Optimization Scheme for Network Mobility Support in Heterogeneous Mobile Networks

With the proliferation of various wireless services such as Third Generation, Fourth Generation, Wireless Local Area Network, and Personal Area Network, etc., users request for access to the Next Generation Internet in more heterogeneous networks. The network mobility working group within the Internet Engineering Task Force introduced the Network Mobility (NEMO) concept as a network mobility basic support protocol (i.e., network moves as a unit) extended from Mobile IPv6 (MIPv6). However, this solution has the limitation of route optimization that should be always passed by Home Agents (HAs) using a bi-directional tunnel with its Mobile Router (MR). It is not also entirely supported a security requirements and various attacks (e.g., Denial of Service attack, redirect attack, etc.). Most of all, it is not mentioned how authentication issues between a HA and a Correspondent Node (CN) are solved in NEMO environments. To ameliorate these problems, we propose novel authenticated route optimization scheme to be performed by MR and CN of Mobile Network Nodes, which uses IDentity-based cryptosystem (that is, a Multi-Private Key Generator Based Authenticated Key Agreement between MRs) to look upon heterogeneous NEMO environments. In performance analysis, we analytically compute the protocol's connectivity recovery and end-to-end delay time and then compare the security and the efficiency of proposed scheme with the NEMO Basic support protocol, i.e., RFC 3963.
