Abstract

Proxy Mobile IPv6 (PMIPv6) protocol was developed through the concept of Network-based Local Mobility Management (NetLMM). IP mobility features previously developed in various other mobility protocols are based on the host. Mobile Node (MN) needs to perform the process of signaling to the network topology involved when roaming to other locations and this scenario has caused problems including the need to implement the complex configuration of host mobility for signaling exchange conditions and route update. Accordingly, the PMIPv6 protocol gets rid of the burden to install mobility stack on MN. A number of mobility management protocols have been proposed for this purpose other than PMIPv6 such as Mobile IPv4 (MIPv4), Mobile IPv6 (MIPv6), Fast Mobile IPv6 (FMIPv6), and Hierarchical Mobile IPv6 (HMIPv6). However, various weaknesses were found in the implementation of mobility management protocol such as packet overhead, latency delivery and lack of support for data access optimization. In addition, analysis of previous studies found that the implementation of mobility protocol introduced high signaling cost, handover delays and the probability of failure of delivery. This paper aims to study investigates the performance of PMIPv6 protocol. Network Simulator (NS) version 2.29 is used to perform PMIPv6 protocol over UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) traffics. The results of the study shown the performance of the PMIPv6 protocol under handover delay, packet delivery ratio and throughput performance metrics.
