摘　　要：针对无线传感器网络(WSN)中多跳路由转发带来的数据冗余传输、簇头网络能耗较大及网络生存周期较短的问题,提出一种全局动态优化的消冗降耗多跳路由发现算法.通过优化路径权重参数,改进多跳路由选择策略.在簇头分配接收数据时隙问题上引入双射频分工方式,减小接收簇头节点信息及向其他节点转发信息带来的数据冗余传输,在减小整个网络耗能的同时尽量避免数据冲突.通过仿真实验将本文算法与现有算法LEACH和EAMMH进行比较,结果表明本文算法的整体系统能耗和网络负载均衡优于另外2种算法.To solve the problems of data transmission redundancy,high energy consumption of cluster head network and short network survival period brought by multi-hop routing and forwarding in wireless sensor networks(WSN),a de-duplication and consumption-reducing multi-hop routing discovery algorithm based on global dynamic optimization is proposed.The multi-hop routing selection strategy is improved by optimizing the path weight parameter.The dual-radio division of labor is introduced in the cluster head allocation to accept data time slots to reduce the data redundancy caused by accepting information from cluster head nodes and forwarding information to other nodes,which reduces the data conflict while reducing the energy consumption of the whole network.The proposed algorithm is compared with LEACH and EAMMH by simulated test,and the results show that the overall system energy consumption and network load balancing of the proposed algorithm is better than the other two algorithms.
