Energy-Efficient Target Coverage in Wireless Sensor Networks Based on Modified Ant Colony Algorithm

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