Evaluating mobility management models for content forwarding in named data networking environments

Named Data Networking (NDN) performs its routing and forwarding decisions using name prefixes. This removes some of the issues affecting addresses in our traditional IP architecture such as limitation in address allocation and management, and even NAT translations etcetera. Another positivity of NDN is its ability to use the conventional routing like the link state and distance vector algorithm. In route announcement, NDN node broadcasts its name prefix which consists of the knowledge of the next communicating node. In this paper, we evaluate the performance of mobility management models used in forwarding NDN contents to a next hop. This makes it crucial to select an approach of mobility model that translates the nature of movement of the NDN mobile routers. A detailed analysis of the famous mobility model such as the Random Waypoint mobility and Constant Velocity were computed to determine the mobility rate of the NDN mobile router. Simulation analysis was carried out using ndnSIM 2.1 on Linux Version 16.1. we build and compile with modules and libraries in NS-3.29. The sample of movement of the mobile router is illustrated and our result present the viability of the Constant Velocity model as compared with the Random Way point.

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

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 scheme for indirection-based mobility approach in named data networking

Named Data Networking (NDN) is a clean-slate future Internet architecture proposed to support content mobility by using hierarchical naming instead of IP addresses for routing. The hierarchical naming structure of NDN offers more benefits in supporting consumer mobility. However, the movements of producer inflict changes in routing name prefix hierarchy, which makes the entire network unaware of the new location of the producer. Thus, it causes some significant challenges, such as unnecessary Interest packet losses, high handoff latency, high signaling overhead cost, poor utilization of bandwidth, and path stretching. The aim of this research is to propose a Producer Mobility Support Scheme (PMSS) in order to minimize the handoff latency, signaling cost, improve data packets delivery via optimal path once a content producer relocated. The proposed PMSS model includes the formulated Mobility Weighted Function to incorporate movement behavior of the mobile producer. Also, Mobility Interest packet was designed to convey binding information and Broadcasting Strategy to facilitate handoff processes by updating the intermediate routers. Therefore, modeling and simulation methodologies were used in the design and performance evaluation of PMSS for rigorous investigation. The analytical result of PMSS scheme outperforms Optimal Producer Mobility for Larger-scale scheme with 50% lower handoff latency and signaling cost. Moreover, it minimizes 46% handoff signaling cost and improves 32% data path optimization as compared to the Kite scheme. The simulation results show that the proposed PMSS scheme minimizes 40% handoff latency, 28% packets delay, 28% unnecessary Interest packets loss, and improves 20% throughput. This study contributes to the development of the movement behavior model and mobility update packets. The findings have significant implication to support seamless mobility and the integration of NDN with other networks without additional mechanism
