碩士 === 國立政治大學 === 資訊科學學系 === 91 === We proposed a framework of MobileLAN. It mainly consists of ad hoc multi-hop networks and has accessibility to Internet. In MobileLAN, group users access Intranet with high bandwidth and access Internet with low bandwidth. The thesis is to solve the following three problems in MobileLAN. First, we proposed a location management protocol due to Internet access and the rapidly moving of mobile clients. We proposed an improved version of Mobile IP to solve multi-hop problem. The protocol consists of registration, location update. Second, we proposed a Location-Based Hybrid Routing (LBHR) protocol to solve the problem of packet delivery in wireless multi-hop networks. LBHR mechanism consists of multicasting, route discovery and route maintenance. Third, we proposed a management strategy to assure QoS. We modified DiffServ to adapt to wireless networks. It makes more efficient use of bandwidth, and thus solves the problem of mobile clients’ mobility. It consists of mappings of network components between DiffServ and MobileLAN, adding bandwidth reservation types, and mobility prediction. In addition, we also proposed a decision model to minimize the communication complexity by analyzing the factors of each part of communication. In the final simulation, we computed the optimum values of these factors, which both minimize the communication complexity and maximize the throughput.
