Enhancements in Mobility Management for Future Wireless Networks

Abstract: The tremendous demands from social market are pushing the booming development of mobile communications faster than ever before, leading to emergence of new advanced techniques. The paper describes about the need for enhancements in mobility management for current and future communication networks and the integration of these heterogeneous networks for a smooth handoff and better Quality of Service (QoS) in the context of next evolutionary step for wireless communication networks. The macro and micro mobility solutions for Mobile IP are analysed and a comparative study is done among HMIP, Cellular IP and HAWAII protocols. The latest changes for Handoff management and location registration are investigated and an outline of the problems regarding the handoffs and QoS to be addressed by the next generation of wireless networks is discussed.

Keywords: Mobility management, Handoff management, Quality of Service, Macro mobility, Micro mobility, HMIP, HAWAII, Cellular IP.
