| In order to investigate performance of Route Optimization, we explored different ways to implement Mobile IP with Route Optimization and chose user space approach by C++ under Linux platform, evaluated the performance and provided our enhancement to the Route Optimization draft. The efficiency gain of Route Optimization will depend on the relative location of the three entities: the mobile node, the home agent and the correspondent node as well as the quality of communication links between the three entities. In most case, the Route Optimization efficiency gain is great and can achieve 17 times in terms of throughput as compared to basic Mobile IP, at the mean time, only 3% losses in terms of throughput as compared to plain IP. To solve deployment difficulty in the plentiful correspondent nodes, we proposed a Binary Exponential Backoff Algorithm (BEBA) to relieve the home agent burden while a correspondent node does not equipped with Route Optimization functionality.
