Application Layer Mobility Supporting by Dynamic Home Agent With Location Awareness
Mobility management is important to wireless networks, but increased speed and efficiency are hampered by problems of triangular routing, signaling overhead and binding cache support. A new approach called Mobile IP with Home Agent Handover (HH-MIP) proposed to enjoy most of the advantages of ROMIP but with only a small increase of signaling overhead. The HH-MIP approach is an efficient mechanism to eliminate ROMIP shortcomings without introduces large signaling cost, and the results show that HH-MIP could reduce both transmission path and handoff latency efficiently as compared with the previous mechanisms. Although HH-MIP has great performance, it demands all routers in Foreign Networks to support combined functionalities of both Temporary Home Agent (THA) and Foreign Agent (FA).
