摘　　要：在无线传感器网络中,节点失效和环境影响等因素会降低数据传输的可靠性。为此,提出一种基于前向纠错的自适应多径路由协议。根据当前的网络状况,利用RS纠删码自适应调整编码冗余,在选出的可用多路径上根据每条路径的剩余能量权重分配流量,Sink节点根据收到的数据片段进行数据包重构。仿真结果表明,该协议能达到较好的负载均衡,具有较高的成功传输率和吞吐率。Due to the node failure and environmental influence, the reliability of data transmission in Wireless Sensor Network（WSN） is lower. Aiming at this problem, this paper presents an adaptive multipath routing protocol based on Forward Error Correction（FEC） for WSN. It adaptively adjusts the coding redundancy based on the current state of the network by RS erasure coding and distributes the traffic according to the weight of the residual energy of each path. The sink node reconstructs the packet based on received segments. Simulation result shows that this protocol can optimally use the wireless link to achieve a better load balance. It has higher successful delivery ratio and the throughput.
