MsDD: A novel NDN producer mobility support scheme based on multi-satellite data depot.

The Named Data Networking (NDN) is currently an important future network framework, and the mobility issue of producers within NDN is a primary challenge. However, in environments characterized by frequent producers mobility, traditional producer mobility support schemes still encounter issues such as excessive consumer delays and interest packet loss. With the development of The 6th generation communication technology (6G), integrating ground networks with satellites has emerged as a potential solution to address the aforementioned problems. In this paper, we propose an NDN producer mobility support scheme based on multi-satellite data depot, named MsDD. The proposed scheme proactively caches producer data into a data depot built on a low-earth orbit satellite constellation to minimize the impact of NDN producer mobility on network performance. We design data depot construction strategy, in-network caching strategy, and routing strategy based on forwarding hint to facilitate effective communication in satellite networks. Experimental results using ndnSIM demonstrate that compared with other existing schemes, MsDD can effectively shield the impact of producer mobility on consumer delay, delivery ratio, and signaling overhead, and MsDD has a clear advantage in terms of consumer delay and delivery ratio.

Distributed Rendezvous placement for producer mobility support in NDN-IoT

Named Data Networking is a new networking architecture proposed as a potential design for the next generation of networks. However, supporting the mobility of producers in NDN-based IoT systems remains an open challenge for researchers to address. To tackle this problem, the NDN research group introduced a solution called KITE [1]. Since this solution is an initial design, some issues to be resolved remain, including the rendezvous placement selection. The location of the rendezvous servers can significantly reduce the path stretch efficiently. This paper focuses on improving the KITE solution by addressing two specific issues. First, we aim to determine the optimal number of rendezvous servers to use in the network. Second, we seek to identify the best locations for the rendezvous servers to minimize the path stretch efficiently. We propose an evaluation metric called average hop count based on network centrality measures to select the number and the location for the rendezvous. We evaluate the Average hop count under different network centrality measures using random scale-free network topology. Our results show that the betweenness centrality measure performs better than other measures, and we, therefore, suggest using it as a metric for selecting the number of rendezvous servers and their locations.

Performance evaluation of route optimization management of producer mobility in information-centric networking

<p class="MDPI17abstract"><span lang="EN-US">Named data networking (NDN) is a network service evolving the Internet's host-based packet delivery model. The idea of NDN is to use named data for routing, which specifies what they are looking for, instead of using location addresses that determine where they expect it to be provided. This architecture is expected to solve many issues that are currently faced by transmission control protocol/internet protocol (TCP/IP) architecture, such as scalability, robustness, mobility, security, and etcetera. One of the problems is about handling producer mobility. Considering the explosion growth rate of Internet connection in public transport vehicles, this is a challenge that needs to be overcome. Therefore, we have proposed a new scheme called route optimization management of producer mobility (ROM-P) with new features such as distributing anchor points and caching by using the same data name and com-paring our previous scheme, efficient producer mobility support (EPMS). This paper shows the analysis result between the ROM-P and EPMS by using simulation. All simulations were conducted using ndnSIM 2.4 NS-3 based. Throughout the simulation ROM-P shows a promising development in better performing compares to EPMS.</span></p>

Comparison of Named Data Networking Mobility Methodology in a Merged Cloud Internet of Things and Artificial Intelligence Environment.

In-network caching has evolved into a new paradigm, paving the way for the creation of Named Data Networking (NDN). Rather than simply being typical Internet technology, NDN serves a range of functions, with a focus on consumer-driven network architecture. The NDN design has been proposed as a method for replacing Internet Protocol (IP) addresses with identified content. This study adds to current research on NDN, artificial intelligence (AI), cloud computing, and the Internet of Things (IoT). The core contribution of this paper is the merging of cloud IoT (C-IoT) and NDN-AI-IoT. To be precise, this study provides possible methodological and parameter explanations of the technologies via three methods: KITE, a producer mobility support scheme (PMSS), and hybrid network mobility (hybrid NeMO). KITE uses the indirection method to transmit content using simple NDN communication; the PMSS improves producer operation by reducing handover latency; and hybrid NeMO provides a binding information table to replace the base function of forwarding information. This study also describes mathematical equations for signaling cost and handover latency. Using the network simulator ndnSIM NS-3, this study highlights producer mobility operation. Mathematical equations for each methodology are developed based on the mobility scenario to measure handover latency and signaling cost. The results show that the efficiency of signaling cost for hybrid NeMO is approximately 4% better than that of KITE and the PMSS, while the handover latency for hybrid NeMO is 46% lower than that of KITE and approximately 60% lower than that of the PMSS.

PMSS: Producer Mobility Support Scheme Optimization with RWP Mobility Model in Named Data Networking

Abstract: The movement pattern of mobile producer plays an important role in mobility performance analysis of the wireless and mobile network. However, the producer mobility behavior is directly affecting the handoff latency and signaling overhead cost. Many researchers provide analytical investigation to analyze and solve the handoff problems and compared with the simulation result. To justify between simulation and analytical investigation, movement behavior of mobile node needs to be included in the analytical investigation to make it possible to compare with the simulation-based result. This paper incorporated Random WayPoint Mobility (RWPM) model, to determine the behavior of mobile producer, for analytical solution of producer mobility support in NDN. In this paper, we introduce mobility Interest packets to conveyed new prefix or location of mobile producer, a broadcasting strategy to facilitate the handoff process and the immobile anchor router was modified to perform a dual function that is, tagging of anchors and broadcasting of tagged mobility Interest packets. The performance analysis for mobile producer behavior and handoff latency shows that our proposed Producer Mobility Support Scheme (PMSS) reduces handoff latency compared to DNS-like and Home Agent routing approach.

Producer Mobility Support in Information-Centric Networks: Research Background and Open Issues

Producer mobility support in information-centric networks: research background and open issues

In recent times, an interesting innovation of information-centric networking (ICN) architecture has been introduced to replace the old fashion host-centric communication architecture with content-centric architecture. With the instant growth of mobile devices and mobile data traffic, the mobility issue in the current IP-based network is growing rapidly and is facing many inefficiencies such as unsupported mobility and data delivery. The unsupported mobility causes failure of the communication system and inaccessibility in the network services. The unsupported mobility stimulates several complications and issues in the network such as unavailability of content, denial of service, interest packets loss, and excessive burden in the network. Further, unsupported mobility affects the routing and forwarding plane in the network and terminates the content transmission to its consumers. Thus, this paper will critically explore this issue. It will present a strong foundation of the producer mobility support architecture, research challenges, previous solutions, and open research issues. Along with this discussion, a research roadmap will be delineated.

OPMSS: Optimal Producer Mobility Support Solution for Named Data Networking

Named data networking (NDN) is designed as a clean-slate Internet architecture to replace the current IP Internet architecture. The named data networking was proposed to offer vast advantages, especially with the advent of new content distributions in IoT, 5G and vehicular networking. However, the architecture is still facing challenges for managing content producer mobility. Despite the efforts of many researchers that curtailed the high handoff latency and signaling overhead, there are still some prominent challenges, such as non-optimal routing path, long delay for data delivery and unnecessary interest packet losses. This paper proposed a solution to minimize unnecessary interest packet losses, delay and provide data path optimization when the mobile producer relocates by using mobility update, broadcasting and best route strategies. The proposed solution is implemented, evaluated and benchmarked with an existing Kite solution. The performance analysis result revealed that our proposed Optimal Producer Mobility Support Solution (OPMSS) minimizes the number of unnecessary interest packets lost on average by 30%, and an average delay of 25% to 30%, with almost equal and acceptable signaling overhead costs. Furthermore, it provides a better data packet delivery route than the Kite solution.

Analytical modelling solution of producer mobility support scheme for named data networking

Named Data Networking (NDN) is a clean-slate future Internet architecture proposed to support content mobility. However, content producer mobility is not supported fundamentally and faces many challenges such as, high handoff latency, signaling overhead cost and unnecessary Interest packet losses. Hence, many approaches indirection-based approach, mapping-based approach, locator-based approach and control/data plane-based approach were proposed to address these problems. Mapping-based and control/data plane-based approach deployed servers for name resolution serveces to provide optimal data path after handoff, but introduces high handoff latency and signalling overhead cost. Indirection-based and locator-based approach schemes provide normal handoff delay, but introduces sub-optimal or tiangular routing path. Therefore, there is needs to provide substantial producer mobility support that minimizes the handoff latency, signaling cost and improve data packets delivery via optimal path once a content producer relocates to new location. This paper proposed a scheme that provides optimal data path using mobility Interest packets and broadcasting strategy. Analytical investigation result shows that our proposed scheme outperforms existing approaches in terms of handoff latency, signaling cost and path optimization.

Optimal Broadcast Strategy-Based Producer Mobility Support Scheme for Named Data Networking

<p>Named Data Networking is a consumer-driven network that supports content consumer mobility due to the nature of in-network catching. The catching suppressed unnecessary Interest packets losses by providing an immediate copy of the data and consumer-driven nature influencedthe mobile consumer to resend unsatisfied Interest packet immediately after the handoff. Once the producer moves to a new location, the name prefix changed automatically after handoff to the new router or point of attachment. The entire network lacks the knowledge of producer movement unless if the producer announces its new prefix to update the FIBs of intermediate routers. Lack of producer’s movement knowledge causes an increase of handoff latency, signaling overhead cost, Interests packets losses, poor utilization of bandwidth and packets delivery. Therefore, there is needs to provide substantial producer mobility support to minimize the handoff latency, handoff signaling overhead cost, reduce the unnecessary Interest packets loss to improve data packets delivery once a content producer relocated. In this paper, broadcasting strategy is introduced to facilitate the handoff procedures and update the intermediate routers about the producer movement. Hence, analytical investigation result of this paper addresses the deficiency of Kite scheme by minimizing handoff signaling cost and provides data path optimization after the handoff.<strong></strong></p>

Producer Mobility Support Schemes for Named Data Networking: A Survey

Mobile devices connectivity and data traffic growth requires scalable and efficient means of data distribution over the Internet. Thus, influenced the needs for upgrading or replacing the current Internet architecture to cater the situation as Named Data Networking (NDN) was proposed. NDN is clean-slate Internet architecture, proposed to replace IP with hierarchical named content that utilizes route aggregation to improve scalability and support mobility. Although, NDN provides supports for content consumer mobility with the help of catching capabilities, however, content producer faces many problems similar to mobility in IP architecture, such as, long handoff delay, unnecessary Interest packet losses and high bandwidth utilization. Hence, many concepts and schemes were proposed to address these problems. This paper reviewed and conceptually analyzed the schemes based on their fundamental design that broadly categorized into indirection-based approach, mapping-based approach, locator-based approach and control/data plane-based approach. In the review analysis, mapping-based approach schemes provide optimal path for packets delivery, high handoff delay Indirection-based and locator-based approach schemes provide normal handoff delay, but introduces tiangular routing path. The control/data plane-based approach schemes provide sub-optimal routing path and high handoff delay. The paper provided both strength and weakness of each scheme for further research.

Space-terrestrial integrated mobility management via named data networking

In Future Space-Terrestrial Integrated Networks (FSTINs), mobility is the norm rather than the exception, the current TCP/IP architecture is not competent. As a promising future network architecture, Named Data Networking (NDN) can support content consumer mobility naturally, but the content producer mobility support remains a challenging problem. Most previous research simply considered this problem in terrestrial scenarios, which involve stable infrastructures to achieve node mobility management. In this paper, we consider the problem in an FSTIN scenario without special handover management infrastructures. Specifically, we propose a tracing-based producer mobility management scheme and an addressing-assisted forwarding method via NDN architecture. We formally describe Multi-Layered Satellite Networks via a Time Varying Graph model and define the foremost path calculating problem to calculate the route of space segment, as well as an algorithm that can function in both dense (connected) and sparse (delay/disruption tolerant) scenarios. Finally, we discuss the acceleration method that can improve the Space-Terrestrial Integrated forwarding efficiency. Performance evaluation demonstrates that the proposed scheme can support fast handover and efficient forwarding in the FSTIN scenario.

A producer mobility support scheme for real-time multimedia delivery in named data networking

Named Data Networking (NDN) is a network architecture for the Future Internet, and can cooperate with the Internet of Things (IoT) to tackle problems existing in the current IP/TCP network architecture. Its consumer-driven paradigm and generic cache could optimize content distribution performance. However, there are still some problems to be dealt with, including mobility support of the producer. This paper proposes a producer mobility support scheme in NDN specifically for real-time multimedia delivery scenarios to reduce handover delay and to improve consumer experience with bounded overhead. Complementary components are designed based on forwarding information bases and packets in the original NDN. In particular, we categorize scenarios into two types according to cache state, and handle them with different strategies. Results of numerical analysis show that our scheme outperforms the original NDN and some typical solutions on delay with bounded overhead.

Efficient Producer Mobility Support in Named Data Networking

Named Data Networking (NDN) is a promising architecture for the future Internet and it is mainly designed for efficient content delivery and retrieval. However, producer mobility support is one of the challenging problems of NDN. This paper proposes a scheme which aims to optimize the tunneling-based producer mobility solution in NDN. It does not require NDN routers to change their routing tables (Forwarding Information Base) after a producer moves. Instead, the Interest packet can be sent from a consumer to the moved producer using the tunnel. The piggybacked Data packet which is sent back to the consumer will trigger the consumer to send the following Interest packets through the optimized path to the producer. Moreover, a naming scheme is proposed so that the NDN caching function can be fully utilized. An analysis is carried out to evaluate the performance of the proposal. The results indicate that the proposed scheme reduces the network cost compared to related works and supports route optimization for enhanced producer mobility support in NDN.

Producer Mobility support in Named Data Internet of Things Network

Abstract: Named-Data Networking (NDN) is a promising candidate for the Internet of Things (IoT) which targets to improve data dissemination efficiency. This new paradigm brings considerable benefits such as minimizing the content producer solicitation and rapid data transmission. However, the producer mobility issue in NDN is not sufficiently addressed. Especially, in IoT scenario, in which devices are frequently mobile and it requires data to keep continuity. In this paper, we present proposed producer mobility solutions in NDN in an IoT context.

Supporting Seamless Mobility for Real-Time Applications in Named Data Networking

Named Data Networking architecture originally provided consumer mobility by design, however content or producer mobility was left unspecified. Since then a number of producer mobility support schemes have been proposed. In this paper, we provide a survey on the most relevant proposed techniques to support mobility in NDN. We classify these mobility support techniques into categories based on their underlying mechanisms of explicit notification, routing, indirection, mapping, and proactive caching. We discuss their strengths and weaknesses, and investigate their appropriateness to accommodate real time requirements necessitated by most of today traffic.
