Abstract:

Mobile IPv6 (MIPv6) and NEtwork MObility Basic Support (NEMO-BS) are protocols presented by the Internet Engineering Task Force (IETF) to enable host mobility on Internet infrastructure. With MIPv6 and NEMO-BS support, mobile hosts can move from one network to another without interrupting ongoing sessions. But these protocols exhibit long delay due to rectangular routing and IP-in-IP encapsulation resulting in network performance degradation. Furthermore, during handover packet loss due to mobility is high which eventually hinder the performance of real application such as video conference, VoIP. Route optimization method is applied in mobile network to avoid rectangular routing thus reducing delay, tunneling overhead and improving packet delivery. In order to contend with the mobile network performance degradation, thesis concerns designing, analyzing, synthesizing and evaluating MIPv6 and NEMO-BS existing handover and route optimization mechanisms. First, we extract and present different handover and route optimization, discussing the related works. Then, we present MIPv6 and NEtwork MObility (NEMO) operations, a single node and whole network support respectively. Later, we proposed route optimization mechanism in MIPv6 based on Early Predictive Binding Update (EPBU). The NEMO communications are categorized in to two scenarios, inter nested NEMO and intra nested NEMO. The Top Level Mobile Router (TLMR) and Adhoc based routing optimization mechanism were proposed based on inter nested NEMO and intra nested NEMO scenario respectively. To evaluate the proposed mechanism, we carry out qualitative analysis as well as quantitative analysis in terms of end-to-end latency, packet loss, tunneling overhead, signaling overhead and route optimization overhead
