摘要: 针对无线传感器网络分簇多跳路由协议中靠近基站的簇头节点容易死亡的缺点,提出一种基于扇形的能量匀衡的非匀均分簇路由协议EBUCBS(Energy-Balancing Unequal Clustering Routing Protocol Based on the Sector).EBUCBS协议采用固定分簇方式能减少重复分簇给网络带来的额外能量损失,且靠近基站的簇的规模小于远离基站的簇规模,使靠近基站的簇头有足够的能量转发信息而不容易死亡,均衡了网络能量负载.Matlab仿真实验表明:与LEACH协议、EEUC协议相比EBUCBS协议有效延长了网络生存时间.Abstract: In clustering and multi-hop routing protocol which used in wireless sensor network,the cluster heads that close to the base station are easy to dead.To address the problem,this paper propose an Energy-Balancing Unequal Clustering Routing Protocol Based on the Sector (EBUCBS). Every node in a curved square form a cluster.When they communicate, cluster heads transfer the information to the base station along the direction of the sector in multi-hop. The experimental results show that EBUCBS protocol is better than LEACH protocol and EEUC protocol in prolonging the life of the wireless sensor network.
