An Energy-Efficient Clustering Algorithm Based on Ant-Colony Optimization

It is one of the nuclear problems how to extend the lifetime of nodes in wireless sensor network,because of the energy-restriction.LEACH is a low-power self-adaptive routing algorithm.But as its stochastic nature,it only forms suboptimal topology and can not induce average distribution of energy consumption.An energy-efficient clustering algorithm based on ant-colony optimization is proposed,using swarm intelligence.Experimental result indicates that the new algorithm is very energy-efficient,which prolongs the lifetime of the sensor network.
