| Summary: | 碩士 === 國立交通大學 === 電子工程系所 === 93 === This thesis proposes a new radio resource allocation (RRM) scheme, called client feedback assisted (CFA) RRM, to improve system resource utilization rate and at the same time to enhance individual quality of service (QoS). The concept of CFA is applicable to all wireless communication systems which tend to serve multimedia applications, especially real-time video streaming. The resource relocation includes rescheduling priorities in a front-end wireless system and reassigning source bit rate of each streaming in a back-end multimedia server. CFA exploits feedback information from a client buffer, current fullness of base station queue, RF condition, and system loading to decide the priority and source bit rate. As compared with a fairness scheduling RRM, which combines client-based and radio network feedback (RNF) as its streaming adaptation scheme, simulation results show that CFA solution can improve system throughput and decrease the probability of client buffer underflow.
