In the wireless sensor networks,high efficient data routing for the limited energy resource networks is an important issue.By introducing Antcolony algorithm,this paper proposes the wireless sensor network routing algorithm based on LEACH.During the construction of sensor network clusters,to avoid the node premature death because of the energy consumption,only the nodes whose residual energy is higher than the average energy can be chosen as the cluster heads.The method of repeated division is used to divide the clusters in sensor networks so that the numbers of the nodes in each cluster are balanced.The basic thought of ant-colony algorithm is adopted to realize the data routing between the cluster heads and sink nodes,and the maintenance of routing.The analysis and simulation showed that the proposed routing protocol not only can reduce the energy consumption,balance the energy consumption between nodes,but also prolong the network lifetime.
