Abstract
Designing clustered routing protocol for Wireless Sensor Networks (WSNs)needs consider the energy of single node and the balance consumption of the whole network energy. Clustering resolves effectively node energy bottleneck and unbalanced consumption of clusters in W SNs. On the basis of analyzing the characteristics and shortcomings of traditional clustered routing LEACH (low energy adaptive clustering hierarchy)protocols and some recent representative improved routing algorithms based on the idea of LEACH, a routing improvements protocol based on clustering in wireless sensor network is proposed. It adopts a new cluster head competition parameter, which can reduce the control message cost of during cluster formation and solve the net nodes energy heterogeneous problem in a better way. Yet it reduces the quantity of cluster-head communicate with the base station by multi-hop. Simulation results show that the protocol can save the node energy consumption effectively and prolong the network lifetime.关键词
