This article proposed one kind based on the ant colony algorithm routing algorithm in wireless sensor networks. According to the election of cluster head node energy, and the use of ant colony algorithm is simple and easy to implement, support for multiple path characteristics, through the adjacent cluster-heads mutual exchange between the respective distances and residual energy value information, resulting in the entire network to establish and update the cluster heads of pheromone concentration, then according to the pheromone concentration calculation adjacent cluster is selected as the next hop routing. Finally, this paper makes use of NS2 simulation tools to test the algorithm. The simulations results show that compared with LEACH algorithm, the algorithm in energy consumption and prolong the network lifetime and have better performance.
