摘要: 网络编码技术应用于无线传感器网络时可增加网络吞吐量及可靠性,同时降低能耗,均衡网络负载,实现保密通信并提高网络安全性。多径路由具有稳定性强和资源利用率高的特点。基于此,研究无线传感器网络的3种多径路由模型:普通多径路由模型,基于网络编码的不相交多径路由模型以及基于网络编码的相交多径路由模型。利用理论推导出这3种模型的成功交付率和标准化冗余度计算公式,并对模型进行仿真及性能比较。结果表明,基于网络编码的相交多径路由模型可靠性高且能耗均衡,更适合应用于无线传感器网络。

Abstract: When the network coding technology is applied in Wireless Sensor Network(WSN),it can improve reliability and throughput in the network,also reduce energy consumption,balance network load,realize communication security and improve network security.Multipath routing has the characteristics of strong stability and high resource utilization.Based on network coding,this paper mainly discusses three kinds of multipath routing models of WSN including the normal multipath routing model,the non-intersecting multipath routing model based on network coding,and the intersecting multipath routing model based on network coding.It deduces formulas of the Successful Delivery Ratio(SDR) and the Normalized Redundancy(NR) on these models,and then simulates the three models and makes comparison.The simulation results show that the intersecting multipath routing model based on network coding has high reliability and balanced energy consumption and is more suitable for WSN.

Key words: Wireless Sensor Network(WSN), network coding, multipath routing, reliability, Successful Delivery Ratio(SDR);Normalized Redundancy(NR)
