An Optimized Mobility Management Architecture Based on Identifier/Locator Split

With the widespread of wireless network, the original TCP/IP has shown some drawbacks in supporting the mobility of network due to the semantic overloading of IP address. Therefore, the identifier/locator split method is put forward to improve the mobility support of network radically by decoupling IP into locator and identifier. In this paper, we propose an optimized mobility management architecture based on identifier/locator split, which introduces transitive routers into the network to avoid the participation of border router during the handover process. Besides, we implement the functions of caching and forwarding on the access router so as to eliminate the packet loss caused by handover. Finally, we evaluate our method and compare it with some typical mobility management models. Result shows that the handover latency is remarkably improved theoretically.
