Since sensor nodes have limited energy, energy efficient routing is very important for wireless sensor network (WSN). LEACH and PEGASIS wireless sensor networks are two classic clustering routing protocols among those protocols developed for WSN. In this paper, a new evolutionary based routing protocol for clustered WSN based on LEACH and PEGASIS is proposed, in which the residual energy and link quality are chosen as the criteria of cluster head selecting. The new algorithm utilizes a link quality evaluation model in Gauss distribution, in which the real-time link information is recorded by a dynamic In the process of cluster formation, cluster head with low residual energy and poor link quality will be replaced with a high energy and excellent link quality node in order to balance the energy and avoid the premature death of nodes, a chain like PEGASIS among the cluster heads is formed to achieve data integration and multi-hop transmission. To compensate the shortcoming of link routing, a reliable transform scheme is also proposed. Theoretical analysis and simulation data demonstrate that the proposed protocol, compared with LEACH, is more efficient to balance and reduce energy consumption and hence prolongs the network lifetime.
