碩士 === 國立宜蘭大學 === 電子工程學系碩士班 === 95 === The wireless communication industry is developing rapidly. During the past few years, the government has made great efforts in setting up wireless network reaching every location without boundaries. With the new wireless technology called Worldwide Interoperability for Microwave Access, there will be higher throughput and distance in the wireless communication and thus more research and investment in this new technology. The project M-Taiwan has already performed experiments in every major city so that commercialization of this technology will be possible. Worldwide Interoperability for Microwave Access works in conjunction with GPS technology named Intelligent Mobile Network Handoff Mechanism to bring up an ideal use for Handoff when WiMax work in Intelligent Transport Systems.Our proposal handoff algorithm combine the GPS technology to provide the WiMax Base Station position on the route focus. We use our algorithm to route the map information to predict the target BSs on the route for handoff. This can greatly reduce the handoff times and the channel utility rate let the system become more stable.Compare with others methods and handoff process in 802.16e standard.Our proposal can vastly improve the handoff times, reduce packet delay and loss with total users in the system.
