  • Load balance and failure tolerance are thecrucial issues for multihomed mobile network. However,existing solutions are still far away from our expectation.In this paper, we first analyze the problems of multihoming in a nested mobile network and review their existingschemes in the eye of load balance and failure tolerance.Then we give a strengthened model of access router tree,where a novel and comprehensive metric for best pathrecognition is proposed to realize the load balance. In order to enhance the failure tolerance of the system, we further propose fast handover algorithms which can be usedwhen burst access failure appears. We perform extensivesimulations to evaluate the proposed scheme. Results indicate that comprehensive load balance and failure tolerance can be achieved. Moreover, our proposed handoveralgorithm achieves least latency of package transmissioncompared with its existing counterparts.
