pal, Sushil and Barik, Annwesh (2015) PSO Based Deployment of Hybrid Sensor Networks. BTech thesis.
With the rapid increase in the usage of wireless sensor networks, it is emerging as a technology for monitoring various physical activities. The essential characteristics of wireless sensor network are coverage, cost, connectivity and lifetime which are dependent upon the number and type of sensors being used for the required task. A random deployment strategy of sensor nodes may cause coverage holes in the sensing ?eld. The work presented here shall mainly focus on deployment strategy of WSNs which will improve the coverage area that poses the biggest challenge to the developers. Most of the problems related to WSNs are modelled and approached as multi objective functions through various genetic algorithms. PSO is one such technique that is e?cient and computationally e?cient in addressing various issues such as optimising sensor deployment and localization of sensor nodes. A modi?ed particle swarm optimization (PSO) technique using grid based strategy has been proposed for sensor deployment which is capable of e?ciently deploying the sensors with an objective of maximizing the coverage ratio. It will determine the optimum location of the mobile nodes after the initial random deployment .The optimality rate of this approach is also higher as compared to other genetic algorithms.
