| Summary: | 碩士 === 國立成功大學 === 電腦與通信工程研究所 === 95 === SVC（Scalable Video Coding）is a new on-going video compression technology. For wireless communication and network transmission applications, the transmission channel will have more flexibility and efficiency by using this technology. Moreover, because of the present of the Ultra-Wide-Band(UWB) technology, which support many kinds of high speed transmit ability, the short range, wireless multimedia transmission application are becoming possible. In this paper, we utilize SVC to design a multi-path search scheme and a route selection mechanism on MBOA（Wimedia）[11]. In order to convey the information to the destination outside the range, need inter-media node and helping to convey, this forms one path promptly, and can utilize multi-path to transfer the information to the destination further, different from using the route set of the amount of Node Disjoint, we consider the path correlation with accepting the basis of seeking as the route, Simulation show that the path correlation can achieve a higher degree of throughput. Implement route choose mechanism according to consider multi-path correlation, the past route is chosen mostly consider with the parameter of the Internet, which does not utilize multimedia flow characteristic and physical layer parameter effectively. Here, Not only utilize the bandwidth valid assurance of the multimedia flow characteristic but also consider MBOA offer the speed of many kinds of conveyance, and the bit error rate caused inherently, become the best flow distributed in the route. Simulation shows that path selection mechanism can choose lower mistake path and there is higher throughput.
