Distributed Mobility Management Support for Low-Latency Data Delivery in Named Data Networking for UAVs

Named Data Networking (NDN) has emerged as a promising architecture to overcome the limitations of the conventional Internet Protocol (IP) architecture, particularly in terms of mobility, security, and data availability. However, despite the advantages it offers, producer mobility management remains a significant challenge for NDN, especially for moving vehicles and emerging technologies such as Unmanned Aerial Vehicles (UAVs), known for their high-speed and unpredictable movements, which makes it difficult for NDN to maintain seamless communication. To solve this mobility problem, we propose a Distributed Mobility Management Scheme (DMMS) to support UAV mobility and ensure low-latency content delivery in NDN architecture. DMMS utilizes decentralized Anchors to forward proactively the consumer’s Interest packets toward the producer’s predicted location when handoff occurs. Moreover, it introduces a new forwarding approach that combines the standard and location-based forwarding strategy to improve forwarding efficiency under producer mobility without changing the network structure. Using a realistic scenario, DMMS is evaluated and compared against two well-known solutions, namely MAP-ME and Kite, using the ndnSIM simulations. We demonstrate that DMMS achieves better results compared to Kite and MAP-ME solutions in terms of network cost and consumer quality-of-service metrics.

Enhancing heterogeneous mobile network management based on a well-founded reference ontology

The fulfillment of the Always Best Connected & Served concept in future mobile wireless networks depends on their ability to maintain a seamless association between the user’s equipment and the network. As a result, many researchers and developers have proposed several decision-support mechanisms to cope with this challenge. One of the promising mechanisms to aid mobile wireless networks in achieving ubiquitous coverage with a seamless connection is semantic reasoning. However, once it relies on ontologies, proper representation of Link and Connection – entities that bind the communication nodes – is paramount. Unfortunately, although several network-related ontologies present these concepts, they are unclear on which entities they bind, nor do they present them simultaneously. Also, the same ambiguity can be perceived in vocabulary recommendations of several telecommunication standard bodies. Our main contribution is the ontological analysis that clarifies the definition of Link and Connection in telecommunication domain. Besides, we analyze their dependencies while refining other concepts such as Medium, Server, and Neighbor. Thus, we provide the foundations for a new network-related ontology to support mobility management in wireless networks.

Determinants of Mobility Management in Higher Education: Evidence from Vietnam

Academic mobility is a popular phenomenon at universities, particularly for promoting knowledge exchange, attracts the attention scientific community in recent years, especially in the context of integration and The Fourth Industrial Revolution (FIR). Indeed, FIR is place convergency many dimensions that make mobility flows at universities more advantageous with unlimited connection and interactions, including virtual space and digital tools for mobility. The paper aims at exploring the key determinants of mobility management in higher education to respond to the impacts of FIR. The conceptual model of this study emphasizes mobility management of high-quality human resources following their contribution process: attraction/recruitment, contribution onsite, and return. The model also shows that both individuals and universities have common and unique interests in enhancing mobility flows while creating knowledge transfer regions. It is important to combine these benefits to create active mobility flows. By analyzing some typical mobility flows in a Vietnam national university Hanoi case study, we emphasized that the current philosophy of Vietnamese universities is mostly to focus on solving the lost mobility flows (brain drain) instead of going hand-in-hand with managing the value of high-quality human resource mobility and connecting networks to make to promote knowledge exchange. Thus, it requires Vietnamese universities should change for adapt to FIR’s impacts with academic mobility and manage mobility of human resources follow all their contribution process. This study explores these topics for their impact on FIR to manage mobility flows of high-quality human resources using assessment data which collected snowball methods. Finally, the paper proposes the policy framework supporting mobility management and priority solutions for promoting the knowledge interactions zones and developing smart platforms for university governance and human resource management adapting with the context of the FIR.

Generating demand responsive bus routes from social network data analysis

Many European cities are establishing mandatory obligations for large mobility demand generators such as business and retail parks, tourist sites and events to develop Mobility Management Plans (MMP). Developing MMPs for events with uncertain spatial demand is a particular challenge.This paper investigates whether reliable demand data can be extracted from mining social network (Twitter) content and using the resulting information to inform the design of commercially viable bus routes from peri-urban areas of Barcelona to a large music event (Canet Rock). Using data from relevant Twitter users, a Twitter influence score was established for each of the 947 municipalities in the Barcelona Region, providing a spatially distributed picture of the demand to attend the event, prior to event ticket purchase. This was used as the basis for planning and delivering 11 new commercially viable event bus routes transporting over 450 additional passengers from peri-urban and more rural areas in the Barcelona Region.This paper demonstrates that the innovation of information mining from Social Networks can provide better comprehension of the demand to support Mobility Management Planning for large events and can radically improve the ability of bus services to serve demand from peri-urban and rural areas.

Analysis of a Decentralized Mobility Management Support for u-City Wireless Network Infrastructure

The number of mobile devices roaming into a ubiquitous city (u-city) continues to rise as wireless systems have been widely deployed. The number of mobile devices also varies with time, and they tend to frequently change their locations. In addition, the available wireless access networks may belong to different domains, administrations, management, and internet service providers (ISPs). A fusion of overlapping heterogeneous wireless access networks (e.g., WiMax, Wi-Fi, LTE, etc.) serves the u-city in order to reach different coverage. In this context, technical challenges arise in mobility management for heterogeneous networks to realize their potential coverage and capacity benefits. This paper deals with the analysis of a decentralized mobility management support for u-City wireless network infrastructure. This scheme takes advantage of the features of the fully-distributed model of networked-based mobility management protocol to alleviate and realize the ubiquitous requirements of a u-City.

SFSH: a novel smart factory SDN-layer handoff scheme in 5G-enabled mobile networks

A smart factory network integrates various wireless networks to provide administrators with advanced factory network management capabilities and optimized services. Supporting smooth handoff management is an important issue in network architecture. Existing handoff management protocols are not sufficient to ensure handoff support in smart factories. This work was conducted to achieve the agility required by the smart factory network. The Smart Factory SDN-layer Handoff (SFSH) technique is proposed to guarantee Quality of Service (QoS) by supporting efficient handoff of devices in a smart factory. We proposes the SDN framework called SFSH for smart factory and a handover algorithm considering and the Received Signal Strength (RSS) and speed for SFSH. Through simple simulation, the SDN framework can flexibly cope with the conditions required by the smart factory, and it can be seen that the performance of SFSH considering RSS is improved over the existing handover process. SFSH uses the location and handoff signaling-delay information of devices in the factory to support mobility management and improve handoff performance in a wireless network environment. The sensitivity of the link layer and network layer is analyzed for handoff performance. Theoretical analysis shows that SFSH works better performance than other solutions.

Internet of Things Mobility Over Information-Centric/Named-Data Networking

Information-centric networking (ICN) is a content-oriented network that uses content instead of traditional IP addresses, it facilitates the content retrieval and calculates downstream paths without the need of an optimal topology. ICN inherits mobility support features in its baseline design. Since the Internet of Things (IoT) faces major problems in supporting mobility management over IP, we believe that ICN would represent a major element in scalable IoT networks. This article discusses the use of ICN as a communication model in IoT environments, focusing on solving the mobility issue. Thus, we survey the relevant work that studies the merger between ICN and IoT, and describe the emergence, evolution, and state-of-the-art mobility approach. This article also presents discussions on major scalability challenges when using ICN as a communication enabler for mobile IoT and highlights key designs and guidelines.

Tunnel-Free Distributed Mobility Management (DMM) Support Protocol for Future Mobile Networks

The number of wireless services and devices have remarkably increased, especially since the introduction of smart phones. The population of mobile nodes (MNs) is now exceeding the traditional non-mobile nodes. Mobility is a key factor in mobile core networks as it is responsible for providing continuous communication when a MN is on the move. Currently, a centralized mobile core network architecture is implemented, which has certain limitations. Distributed mobility management (DMM) is often seen as a solution to the problems associated with centralized mobility management (CMM). Address and tunneling management are big challenges for current DMM-based mobility protocols. Keeping in mind the current advancement of mobile network architecture, this paper proposes a novel tunnel-free distributed mobility management support protocol intended for such an evolution. In addition, the performance of the existing DMM IPv6 mobility management protocols in the context of handover latency, handover blocking probability, and data packet loss is analyzed and compared to the proposed framework. The performance analyses show that the proposed tunnel-free method can reduce about 12% of handover latency, 71% of handover blocking probability, and 82% of data packet loss.

Assessing 50 innovative mobility offers in low-density areas: A French application using a two-step decision-aid method

In this article we propose a decision-aid tool for local authorities to plan and implement their transport policies. We set out sustainable-mobility scenarios that depend on the geographical contexts of different areas based on 50 mobility offers, including active modes, car-sharing, public transport, etc. To do so we appeal to a multi-criteria decision analysis (MCDA), relying on an original two-step assessment method. We first use the diviz decision-aid tool to obtain a global score for each mobility offer, on the basis of 18 criteria covering the three pillars of sustainable development (economy, environment and society) and the concerns of the mobility actors themselves (historical actors, newcomers, public authorities and users). This step supports mobility management by local authorities, as it makes it possible to rank mobility offers by type of area. Second, we use the MICMAC decision-aid tool to construct the influence and dependency relationships between our 18 criteria. The aim of this step is to identify some relevant criteria that are determinant in a prospective or strategic analysis, in order to consider what could be a development scenario for the future of everyday mobility in various areas. As alternatives to personal car are rare, we apply this two-step method to the case of low-density areas, and find highlighting results concerning the role of carpooling combined with walking, both being assisted by a powerful mobility application.

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%).

A Novel SDN-based Cross Handoff Scheme in Industrial Mobile Networks

Supporting smooth handoff management in integrated smart factory architecture is an important issue. Existing handoff management protocols are not enough to ensure handoff support for Industrial Networks applications. SDN-Based Industrial Cross Handoff (SBICH) protocol technique was developed to support efficient handoff management between Industrial Networks. SBICH supports mobility management in wireless network environment and uses mobile speed and handoff signaling delay information to improve handoff performance. We analyze this handoff performance. This analysis shows that the performance is quite high.

A Study of a Seamless Handover Support for WSN based Information Transmission in Structural Health Monitoring Systems

The efficiency and safety of social-overhead capital (SOC) public infrastructures have become an eminent social concern. In this regard, a continuous structural health monitoring has been widely implemented to oversee the robustness of such public infrastructures for the safety of the public. This paper deals with the analysis of a distributed mobility management (DMM) support for wireless sensor network (WSN) based information transmission system. The partial DMM support separates the data and control plane infrastructures, wherein, the control plane is managed by a particular mobility management network entity, while the data plane is distributed by the mobility anchors. The system will be able to optimize the information transmission for a wireless structural health monitoring of SOC public infrastructures specifically designed for bridges, and thus, guarantees the safety of public commuters.

Analysis of a NEMO enabled PMIPv6 based Mobility Support for an Efficient Information Transmission

Nowadays, wireless sensor networks (WSNs) have been widely adopted in structural health monitoring (SHM) systems for social overhead capital (SOC) public infrastructures. Structural health information, environmental disturbances and sudden changes of weather conditions, damage detections, and external load quantizing are among the capabilities required of SHM systems. These information requires an efficient transmission with which an efficient mobility management support for wireless networks can provide. This paper deals with the analysis of mobility management schemes in order to address the real-time requirement of data traffic delivery for critical SHM information. The host-based and network-based mobility management protocols have been identified and the advantages of network mobility (NEMO) enabled Proxy Mobile Internet Protocol version 6 (PMIPv6) have been leveraged in order to address the SHM information transmission needs. The scheme allows an efficient information transmission as it improves the handover performance due to shortened handover latency as well as reduced signaling overhead.

RETRACTED: Constrained application for mobility management using embedded devices in the Internet of Things based urban planning in smart cities

Abstract The Constrained Application Protocol (CoAP) has been widely used, as the number of embedded sensors or devices increases. To support mobility management in web based Internet-of-Things environment is critical issue. For this purpose, a CoAP-based mobility management protocol, named CoMP has been proposed, but this protocol was designed for a single sensor node mobility. However, it does not perform well in group-based mobility. To overcome this limitation, we propose a CoAP-based group mobility management protocol, named CoMP-G. In the proposed scheme, one of the body sensor will function as a coordinator and it will exchange all the control messages with web-of-things mobility management system (WMMS) on behalf of other body sensors. Besides, each WMMS maintains the information of the group of body sensors. From the numerical analysis, we proved that the proposed scheme gives the best performance in terms of total signaling and handover delay from the existing CoMP protocol.

Location-based IoT applications on campus: The IoTtalk approach

The National Chiao Tung University is deploying several location-based IoT applications on campus based on an IoT device management platform called IoTtalk. The applications include dog tracking, emergency buttons, and indoor/outdoor environment conditions monitoring (PM2.5, temperature, CO2, and so on). Some of the IoT devices for these applications have simple hardware structures to save energy, and therefore are not equipped with the positioning sensors (e.g., GPS or iBeacon). To support mobility management for these simple IoT devices, we develop a location finding mechanism in IoTtalk. By introducing the locator device in IoTtalk, we can effectively support mobility management for simple IoT devices that does not have location positioning capability. We describe how to develop the device applications to accommodate the location update feature, and show how to configure the location finding mechanism through the IoTtalk GUI. Then we conduct analytic analysis and simulation to investigate the accuracy of location tracking and power consumption for the dog tracking application.

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.

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%).
