Modified Discrete Binary PSO based Sensor Placement for Coverage in WSN Networks

The main idea of this paper is to solve coverage problem in distributed wireless sensor network (WSN) by increasing sensor nodes coverage. This paper proposes a modified discrete binary particle swarm optimization algorithm for Wireless Sensor Network (WSN) nodes placement so that the maximum coverage is obtained.PSO is a real value algorithm, and the discrete PSO is proposed to be adapted to discrete binary space. The proposed algorithms are going to solve the problem by considering the factor on the sensor deployment scheme, given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage. The proposed method on sensors surrounding is examined in different area. The results not only confirmed the successes of using new method in sensor replacement, but also they showed that the new method performs more efficiently.
