对Leach协议簇头节点选取策略进行改进,选取簇头节点时考虑了节点能量、节点配置密度.并由此提出了NCHS-Leach(Novel Cluster Head Selecting Leach)协议.借助NS2仿真证明,相对于Leach算法,NCHS-Leach协议可以将网络寿命延长20%~30%.
The Leach's head selecting scheme does not consider the node's remaining energy, the node's sense density. In this paper, the Novel Cluster Head Selecting Leach (NCHS- Leach for short) is introduced to solve the problem above. Simulation Result in NS2 proves that the lifetime of the network can be prolonged by 20 % -30 %.
