| 摘 要： | 在无线传感器网络（WSNs）中能量负载不均衡问题，影响了网络的生命周期。提出一种基于聚合度模型的WSNs双簇头分簇路由协议（DCHP），DCHP协议将节点聚合度与剩余能量作为考虑因素引入阈值计算，从而使高剩余能量且聚合度高的节点优先选为第一簇头。在此基础上，根据簇内节点能量选出第二簇头，完成簇间多跳路由转发数据。仿真实验表明：DCHP协议能更好平衡网络能量负载问题，延长网络生命周期。

| Abstract: | Energy load imbalance problem in wireless sensor networks （WSNs） affects network lifetime. A double cluster-heads clustering routing protocol （DCHP）based on polymerization degree model is presented, and DCHP protocol introduces node polymerization degree and remaining energy as consideration factors into threshold value calculation, so that elect the first cluster-head prior from high residual energy and high degree of polymerization of node. On this basis, according to energy of in cluster nodes to choose the second cluster-heads, complete data transmission with multiple hops routing in variety clusters. Simulation results show that DCHP protocol can better balance energy load in network and prolong network lifetime. |
