The success of next generation wireless networks will rely much on advanced mechanisms for seamless mobility support among emerging heterogeneous technologies. Currently, mobile IP is the most promising solution for mobility management in the Internet. Several IP micro mobility approaches have been proposed to enhance the performance of Mobile IP which supports quality of service, minimum packet loss, limited handoff delay and scalability. Recent efforts are focusing on providing seamless handover, fault tolerance, reliability and continuous end-to-end service connectivity on the move minimizing the delay and disruption period for real time applications and hence, failures that inhibit communications or result in loss of critical data will not be tolerated. The goal of this paper is to develop a Fault Tolerant HA WAII (FT- HA WAII) protocol and investigate the performance in Tree and partial Mesh routing topologies. Simulation results show that FT- HA WAII can effectively resolve the fault tolerant problem in domain based wireless access networks.
