| Summary: | 碩士 === 銘傳大學 === 資訊管理學系碩士在職專班 === 92 === This thesis presents a Bandwidth Degradation QoS scheme for Adaptive Multimedia services in next generation Wireless/Mobile networks. The 4th generation or beyond 3rd generation of mobile system will provide differential data services (Real-Time service and Non Real-Time service). Since the wireless mobile system resources are particularly scarce over a radio interface, the efficient resource allocation becomes an important issue.
We introduce service degradation QoS scheme for adaptive multimedia service in mobile networks to improve the performance of channel allocation. The proposed schemes are the generic Call Admission Control (CAC) algorithm and the admission policy to support multiple rates, multiple class traffic of next generation mobile network.
Based on diverse QoS parameters be included in connection request, a Two-Stage Bandwidth Degradation QoS CAC algorithm is presented to satisfy the diverse QoS requirement and utilize the system resource efficiently. The simulation results show that the performance of our scheme is preferable to that of existing schemes.
