摘要
为了提高大型无线传感器网络的稳定性,延长网络出现首个节点的死亡时间,提出一种基于簇结构稳定的分环多跳路由算法CBSM(Cluster structure stability based Sub-ring algorithm over multi-hop routing).CBSM算法将监测区域划分为许多固定小区,采用基于节点剩余能量和节点位置的代价函数选择簇头.仿真结果表明,基于簇结构稳定的多跳路由算法,能有效延长网络出现首个节点死亡的时间,提高整个网络的稳定性.
The cluster structure stability based sub-ring algorithm over multi-hop routing（CBSM） is proposed to improve the stability of the wireless sensor network（WSN） and to prolong the lifetime of the network.The main idea of the CBSM is to divide the monitoring area into a number of fixed cells.Then select the cluster head with the residual energy and the nod location in the fixed cell.The simulation results showed that CBSM has a good performance in prolonging the network lifetime and increasing the network stabilization.
