| 摘 要： | 通过均衡网络能量消耗和延长网络生命周期，以提高无线传感器网络的能量利用率，提出了在无线传感器网络动态成簇算法中对簇头节点进行网络编码的路由算法.在簇的建立阶段，采用节点剩余能量和接收信号强度来完成分簇，解决了部分节点因能耗过度而过早失效的问题；在数据采集阶段，采用基于簇头进行随机线性网络编码的方法，有效降低了传输到网关节点数据包的数量，减少了网络能量的耗用.仿真实验结果表明，该算法与标准协议AODV相比，有效的均衡了节点能量消耗，提高了能量使用效率，改善了网络吞吐量和端到端延迟.

| Abstract: | By the extension of network life cycle and the balance of network energy consumption, in order to improve the energy utilization rate of wireless sensor networks, we proposes a routing algorithm for network encoding of cluster head nodes in the dynamic clustering algorithm in wireless sensor network. In the stage of establishing a cluster, the residual energy of nodes and the received signal strength are used to complete clustering, solving the problem of premature failure of some nodes due to excessive energy consumption. In the stage of the data acquisition, the method of random linear network encoding based on cluster head effectively reduces the number of packets transmitted to the gateway node, and the cost of network energy. Simulation results show that compared with the standard protocol AODV, the proposed algorithm can effectively balance the node energy consumption, improve the energy efficiency, and improve the network throughput and end-to-end delay. |
