摘　　要：结合机会路由和网络编码2种技术提出了一种新的任意路径编码感知机会路由方案.为了合理地选择候选节点和分配节点转发优先级,提出了编码感知期望传输次数度量标准.路由方案在无线传输过程中充分利用流间网络编码减少传输次数,从而提高网络传输效率.仿真实验结果表明,路由方案能大幅度提高网络的转发效率和吞吐量.Combined opportunistic routing and network coding, a new any-path coding-aware opportunis- tic routing scheme is proposed. For reasonably choosing candidate forwarding nodes and assigning the nodes forwarding priority, the expected coding-aware transmission metric is presented. This routing scheme takes advantage of the inter-flow network coding to reduce the transmission numbers, and then improves the transmission efficiency. As the simulation is showed, it can improve forwarding efficiency and throughput of the network.
