A Novel Reverse Rerouting Mechanism in Mobile Wireless Internet

In this paper, based on the analysis of existing partial and complete rerouting mechanisms, a novel reverse rerouting mechanism in mobile wireless Internet is presented, taking the characteristics of handover into account. It integrates a reverse rerouting algorithm with the resource handover and reservation mechanisms. Simulation results have shown that the signaling overhead for handover gets effective control, high resource utilization is achieved, and QoS (Quality of Service) guarantees are provided to mobile users to certain degree.
