| 摘 要： | 针对多径路由容易产生报文乱序和丢包现象,将网络编码技术引入到多径路由中,建立两种基于网络编码的无线传感器网络多径路由模型.通过源节点和中继节点的编码以及目的节点的解码,在报文乱序和部分丢包的情况下仍然可以恢复出源数据包,达到降低网络冗余度的同时,提高网络成功交付率.提出根据网络规模选择路由的思想进行仿真计算,结果表明两种模型适合于不同规模的网络.

| Abstract: | Multipath routing can make message disorder and message loss easily.So that,Network coding is introduced into the multipath routing to solve the problems and two multipath routing models based on network coding are set up.Through encoding on source node and relay nodes,and decoding on the receiver,it can recover the source data if packet disorder and parts of packet loss,which greatly promoted the network performance.By simulating the models,the two models suitable for different sizes of network is found.At last,a method is proposed to choose the best routing according to network scale. |
