Cross layering design of IPv6 Fast handover in mobile WiMAX

Over the past few years, rapid advances in wireless broadband networks have been driving the evolution of communication and network technologies towards new mobile services for users. Handover management is still one of the most challenging issues to be solved for seamless mobility in wireless networks. To support mobility on terminal stations mobile WiMAX has been standardized. Moreover to provide seamless communications for such network Fast Mobile IPv6 (FMIPv6) has been proposed by IETF. But for seamless handover, collaboration of layer 2 and layer 3 is required. Thus, there is a requirement for cross-layering design to support proper behavior of the MIPv6 nodes in WiMAX networks. In this article we proposed a cross layer Fast handover solution able to optimize mobility management over mobile WiMAX networks in terms of handover delay and signaling load. The simulation results illustrate that the proposed mechanism achieves better performance in the handover latency and the service disruption time.
