One of the major issues in Target-coverage problem of wireless sensor network is to increase the network lifetime. This can be solved by selecting minimum working nodes that will cover all the targets. This paper proposes a completely new method, in which minimum working node is selected by modified Ant colony Algorithm. Experimental results show that the lever of algorithmic complication is depressed and the searching time is reduced, and the proposed algorithm outperforms the other algorithm in terms.
