Proxy Mobile IPv6 outperforms previous mobilityprotocols have been standardized by the InternetEngineering Task Force. However, Proxy Mobile IPv6 stillinvolves the triangle routing problem in where data packetsfor the mobile node are delivered throughout inefficientrouting paths. To address the triangle routing problem, twodifferent Route Optimization schemes proposed that excludethe inefficient routing paths by creating the shortest routingpath. In this paper, we proposed Correspondent InformationRoute Optimization scheme solves the problem by inefficientsignaling cost of Dutta’s route optimization. Using CorrespondentInformation for Correspondent binding updatesprocess between the mobile access gateways which arecaused by bi-path data communication of the mobile entitiesof different the mobile access gateway on the same localmobility anchor. The results of signaling cost performanceevaluation show that performance of our proposed usingcorrespondent information route optimization scheme isbetter than Liebsch’s route optimization scheme as 45%for mobility of the data packets sender and Dutta’s routeoptimization scheme as 20% for mobility of the data packetssender.
