摘要

<FONT face=Verdana>使用以视频质量为中心的跨层设计思想，把应用层视频质量建模为网络层行为的函数，将用于视频传输的多跳无线局域网的结点带宽分配问题归结为整个网络范围内的流传输路径选择和码率控制问题，带宽调度优化的目标是使接收端总解码视频质量最佳，给出一个基于遗传算法的启发式方案以求解该优化问题并证明了算法的有效性.

Abstract

<FONT face=Verdana>Model the endtoend distortion based video quality as a function of network layer packet loss and delay

and formulate a networkwide optimal routing and rate allocation problem that minimizes the total video distortion.A genetic algorithm based heuristic solution is proposed to solve this optimization problem.The evaluation results show that the proposed solution is efficient and robust enough to adapt the video requirements dynamics.
