Performance analysis of micromobility protocol in mobile IP networks

摘要

The IETF mobile IPv6 protocols have been developed to manage macromobility. There are several protocols such as hierarchical mobile IP, cellular IP and Hawaii have been defined to solve the IP micromobility problem. In these protocols, a tree access network topology is assumed. An actual network topology would be a mixture of a tree and mesh topology. The redundant links present in the partial mesh topology helps in load balancing and delivering of datagrams to the mobile host even in the case of link failure, which increases the robustness of the networks. In this paper, we evaluate and compare the performance analysis of Hawaii micromobility protocol in the proposed partial mesh topology and hierarchical topology. From the results, it is observed that the best performance is achieved in the partial mesh topology; the Hawaii protocol uses the presence of extra link in mesh topology to provide the remarkable improvement in handoff latency, UDP packet loss, or duplication.
