基于遗传算法的无线传感器网络非均匀分簇路由协议
An unequal clustering routing protocal for wireless sensor networks based on genetic algorithm
摘要
Abstract
The imbalance of energy consumption in wireless sensor networks(WSNs)easily results in the"hot spot"problem that the sensor nodes in a particular area die due to fast energy consumption.In order to solve the"hot spot"problem in WSNs,we propose an unequal clustering routing algorithm based on genetic algorithm(UCR-GA).In the cluster head election phase,the fitness function is constructed based on the residual energy,density and distance between nodes and base station,and the appropriate node is selected as the cluster head.In the data transmission phase,the cluster head selects single-hop or multi-hop communication mode according to the distance to the base station.After we comprehensively consider the residual energy of the cluster head and its communication energy consumption with the base station,an appropriate relay node is selected.The designed protocal is simulated under energy homogeneous and energy heterogeneity conditions,and the results show that the proposed routing protocal can effectively balance energy consumption,prolong the life cycle of network,and is appicable to heterogeneous networks.关键词
