Performance Analysis of Route Optimization on Proxy Mobile IPv6

In the mobile IPv6 (MIPv6), a mobile node (MN) directly manages its signaling related mobility because the MIPv6 is a host based mobility protocol. On the other hands, the proxy mobile IPv6 (PMIPv6) provides a network based mobility in where special network entities manage all gnaling related mobility for supporting mobility service of MN. The route optimization (RO) mechanism for PMIPv6 is proposed while the specification of PMIPv6 is still focusing on basic operations. The RO mechanism establishes the enhanced communication path between MNs so that it can reduce transmission delay and network burden. In this paper, we analyze the performance of RO mechanism compared with the basic PMIPv6. The presented results confirm that the RO mechanism provide the improved performance during the MN communicates with the CN, due to the established communication path.
