Using Correspondent Information for Route Optimization Scheme on Proxy Mobile IPv6

Abstract

Proxy Mobile IPv6 outperforms previous mobility
protocols have been standardized by the Internet
Engineering Task Force. However, Proxy Mobile IPv6 still
involves the triangle routing problem in where data packets
for the mobile node are delivered throughout inefficient
routing paths. To address the triangle routing problem, two
different Route Optimization schemes proposed that exclude
the inefficient routing paths by creating the shortest routing
path. In this paper, we proposed Correspondent Information
Route Optimization scheme solves the problem by inefficient
signaling cost of Dutta’s route optimization. Using Correspondent
Information for Correspondent binding updates
process between the mobile access gateways which are
caused by bi-path data communication of the mobile entities
of different the mobile access gateway on the same local
mobility anchor. The results of signaling cost performance
evaluation show that performance of our proposed using
correspondent information route optimization scheme is
better than Liebsch’s route optimization scheme as 45%
for mobility of the data packets sender and Dutta’s route
optimization scheme as 20% for mobility of the data packets
sender.
