英文摘要： This project meets the requirements of new generation railway telecommunication information system. After studies deeply the mobile IP mechanisms, principles and related theories, the architecture, model and theory of the multi-hop multi-access mobile Internet are proposed and formed. Firstly, the architecture and algorithms of the multi-hop multi-access mobile Internet are proposed. Targeting the problem with the larger location update messages generated in the moving process of mobile router and multi-hop routing optimization, the routing model and algorithms are created. The features of our project are network based mobility management, routing algorithms integrated MANET and NEMO protocols and policy based multi-access handover algorithms. Secondly, the performance model and analysis with protocol layer cross mechanism are given. The mobility model, end to end delay and packet drop probability model are presented. Through theory analytical and simulation trial methods, the impacts of various system parameters of the link and network layer on the performance of routing and transportation protocols are studied. Then, the multi-hop multi-access mobile routing algorithms are optimized. The objects of our project are to publish papers indexed by SCI, SCTP, EI, to summit IETF drafts, to apply patents of national invention and to train PhD students.
