摘　　要：该文分析了传感器网络多径路由在不同模型和条件下数据包成功交付率,以及整个系统节点的能耗总量和能耗均衡,将最优节点间距的配置方案引入到多路径网络模型,并根据随机线性网络编码技术设计基于网络编码的多路径路由模型。理论分析和仿真实验证明,使用了网络编码技术的多径传输模型能够更好地保证数据传输可靠度,同时最优节点间距配置方案均衡并减少了网络中节点的能量消耗,延长了网络寿命。The successful delivery rate of packets,total energy consumption and energy balance at nodes of the whole system in different models and conditions for sensor networks with multipath routing are analyzed here.A configure scheme of optimal distance among nodes is employed into a multi-path network model.According to the mechanism of random linear network coding,a multi-path routing model on the base of this kind of network coding is designed.The results of theoretical analysis and simulation experiment show that the multi-path routing with network coding can improve the reliability of data transmission,meanwhile,the configure scheme of optimal node distance makes energy consumption balanced and reduced in the network,then extends the lifetime of sensor networks.
