摘要

One main problem of video multicasting for heterogeneous destinations is the assignment of video descriptions and the construction of multicast tree. However, the assignment of MD video and the construction of multicast tree can greatly affect the user satisfaction (i.e., affect the quality of the received video). In this thesis, we introduce novel approaches to improve the user satisfaction for a set of heterogeneous multicast destinations. The main idea of our approaches is to employ the independent-description property of MDC along with multiple multicast trees. However, many questions are raised: How multiple multicast trees should be constructed? And how MD video should be assigned? Is it better to construct multiple multicast trees first and then assign the video descriptions? Or is it better to assign the video descriptions first and we then construct multiple multicast trees? Should we perform that in a distributed manner or in a centralized one? To answer these questions, we propose different algorithms to construct multiple multicast trees and to assign MD video. The proposed algorithms are: Serial MDC, Distributed MDC, and Centralized MDC. Furthermore, we use our proposed algorithms to develop different multicast protocols for video multicast over wireless ad hoc networks. These protocols take many issues into consideration, rejoining and joining a multicast group, multicast trees maintenance, and mobility of nodes, for example.;Keywords: Multicast, Wireless ad hoc networks, Video streaming, Multiple description coding

MD视频应如何分配?首先构造多个多播树然后分配视频描述更好吗?还是先分配视频描述然后再构造多个多播树更好?我们应该以分散方式还是集中方式执行该操作?为了回答这些问题,我们提出了不同的算法来构造多个多播树并分配MD视频。提出的算法是:串行MDC,分布式MDC和集中式MDC。此外,我们使用提出的算法来开发用于无线ad hoc网络上的视频多播的不同多播协议。这些协议考虑了许多问题,例如重新加入和加入多播组,多播树维护和节点移动性。关键字:组播,无线自组织网络,视频流,多描述编码
