A New Positioning Method using Ant Colony Optimization in Wireless Sensor Networks

Network coverage in sensor positioning is an important challenge of wireless sensor networks. This problem is an NP-hard problem and employing an optimization method is needed. In this paper, we propose an efficient method based on Ant Colony Optimization (ACO) to the sensor positioning to gain better performance by trying to increase the coverage area of the network. We also investigate other intelligent techniques for node positioning to increase the coverage of wireless sensor network.
