Improved distributed regional location management scheme for mobile IP

Ahsrwclhlobile IP is the current standard supporting user muhilit? in wireless IP networks. Mobile IP regional registration is proposed b) IETF ts reduce the Mobile IP location update cost I)! making the registration localized. A distributed regional relistration scheme is also introduced to choose the GFAs dynamicdlly. In the distributed scheme, the signaling burden is evenib distributed among the network and the regional network boundary is dynamically adjusted according to the mobile user's up-to-datr mobility and traffic load. In this paper, we develop a system model to analyze the distributed scheme performance. W e also propose an improved distributed scheme which is called improved distributed regional location management scheme in our paper. The analytical results sbow that the dynamic scheme cdii redace the Mobile IP mohili t j management cost effectively and the improved scheme can perform better.
