摘要：

将网络协议栈的跨层优化设计思想应用于多媒体无线传感器网络,提出一种基于视频编码峰值信噪比最优的跨层多径路由协议.在跨层多径路由模型中,以最大化应用层的多描述编码（MDC）峰值信噪比作为优化目标,通过物理层的丢包率测量和MDC层的信道容量估计联合确定网络层的多径路由属性,MDC的每个描述被映射到多条链路独立的路径上分别传输,最终在Sink节点进行汇聚.对随机生成的网络拓扑求取最小跳数节点的独立两路径路由和跨层多径路由,将Foreman视频分割成2个描述编码视频沿不同路由进行传输,仿真结果验证了跨层多径路由能够降低丢包率和提高平均PSNR.跨层多径路由协议能够提高MDC视频在无线传感器网络中的传输质量.
Abstract:

This work applied the cross-layer design philosophy of network protocol stack to multimedia wireless sensor networks and proposed a novel cross-layer multi-path routing protocol to maximize the peak signal to noise ratio (PSNR) of multiple description coding (MDC) video. In the proposed cross-layer multi-path routing model, to maximize MDC video's PSNR of the application layer is the optimization objective, furthermore, the frame loss ratio estimation of physical layer and the channel capacity estimation of MAC layer decide the multi-path routing properties jointly. Finally, each description of the MDC video is mapped to different link-disjoint paths for transmission independently and received by the sink node to recompose. Foreman video sequence was divided into two descriptions and transmitted along different paths which were derived by minimal hop routing with node-disjoint two paths and the proposed cross-layer multi-path routing of random topology. Simulation results verified that the cross-layer multi-path routing can reduce the frame loss ratio and improve the average PSNR. Consequently, the cross-layer multi-path routing protocol can improve the video transmission quality over wireless sensor networks．
