摘要: 提出一种能量均衡的无线传感器网络两层分簇路由协议TL-EBC。该协议采用粒子群优化算法实现网络节点最优化组簇,设置总簇头负责收集、处理簇头数据并发送至基站,以均衡不同位置簇头间的能耗。仿真结果表明,TL-EBC能有效降低节点死亡速度,均衡网络能耗,延长网络生存周期。

Abstract: An Energy-Balanced Clustering routing protocol of Two-Layer hierarchy(TL-EBC) for Wireless Sensor Network(WSN) is proposed. TL-EBC is a centralized clustering protocol of two-layer hierarchy, which is compact, energy-aware and energy-consumption-balanced. In the lower layer of the protocol, the optimal clustering of all nodes using the Particle Swarm Optimization(PSO) algorithm is realized. And in the upper layer, the chief-cluster-head, which is responsible for collecting, aggregating the data of all cluster heads and sending the fused data to the base station, is selected. Simulation results show that the protocol can efficiently decrease the dead speed of the nodes and prolong the network lifetime.

Key words: Wireless Sensor Network(WSN), clustering routing protocol, Particle Swarm Optimization(PSO) algorithm, two-layer hierarchy clustering, energy consumption, network lifetime
