基于非均匀分簇的无线传感器网络路由协议设计与研究

Research and Design of the Wireless Sensor Network Routing Protocol Based on Non-Uniform Clustering

针对目前均匀分簇路由协议中存在的簇间能耗不均衡问题和簇首选择的不合理等问题,提出改进方案,形成一个新的无线传感器网络非均匀分簇路由协议UCRP,这个协议充分考虑传感器节点的剩余能量,且基于剩余能量优先选择簇首,并改进LEACH路由协议中单跳通信消耗能量大的缺点。在NS2仿真平台上对协议进行仿真实验,将UCRP算法与原LEACH协议进行比较,结果表明,UCRP算法能很好地均衡网络耗能,并延长网络的生存时间。

For the current uniform clustering routing protocol exists between the cluster and the cluster energy imbalance and other issues first choice is unreasonable, an improved scheme, eventually forming a new wireless sensor network clustering routing protocol inhomogeneous UCRP, the agreement fully considers the residual energy of sensor nodes, based on residual energy select cluster head, and improves LEACH routing protocol in single hop communication energy consumption big disadvantage. Campared the NS2 simulation platform for protocol simulation, the simulation results, UCRP algorithm with the original LEACH protocol, the results show that UCRP algorithm is well-balanced network energy consumption and prolong the survival time of the network.
