摘　　要：针对编码机会对数据流传输相对集中的要求,而数据流集中可能会造成传输干扰增大的问题,提出一种新的考虑干扰感知的编码意识路由判据ECXWI,结合一定的路由发现、路由维护机制,形成一种新的编码意识路由算法CARWI,该算法综合考虑了编码机会以及无线传输干扰等因素。仿真证明,并与采用最短路径路由的网络编码机会路由传输机制COPE相比,CARWI在网络吞吐量、端到端时延指标上有更优的表现。For the transmission of data stream required by network coding is relatively concentrated, there may cause the increas- ing interferences, a new routing metric ECXWI is proposed in this paper. Combined with the route discovery and the route maintenance mechanism, a new coding-aware routing algorithm CAR WI is also proposed. Simulation shows that compared with network coding opportunities routing transmission mechanism COPE based on the shortest path route, CARWI has a bet- ter performance of network average throughput, average end to end delays .
