Abstract: With the architectural features of mobile wireless Internet and the characteristics of user mobility taken into account, a reverse rerouting mechanism is presented on the basis of an analysis of partial rerouting and complete rerouting mechanisms. The proposed mechanism integrates reverse rerouting algorithm with resource handover/reservation seamlessly, and carries out reverse rerouting or complete rerouting alternatively as the case may be. Simulation results showed that the mechanism enables the signaling overhead for handover to be reduced and the network resource utilization rate improved, so as to provide significant support to mobile users' the QoS (quality of service) guarantees.
