摘　　要：提出一个支持无线网络编码技术COPE的按需路由协议OCR,以提高无线mesh网中的网络吞吐量。在路由发现过程中,该协议主动地探测编码机会并灵活地寻求"增加编码机会"、"最短路径"以及"避免拥塞"之间的折衷。仿真结果表明OCR能够有效地发现编码机会,进而使得网络拥有更高的吞吐量。A new wireless routing protocol called OCR was presented, enhancing throughput of unicast traffic in wireless mesh networks （WMN）. In the routing discovery, OCR could actively detect the possible coding opportunities and make a tradeoff among these factors： utilizing the coding opportunities, finding the shortest path and neatly avoiding the congestion. The simulation results show that the network throughput can be greatly improved by OCR, compared to the traditional routing protocol, when using COPE.
