Abstract :The dynamic deployments of Wireless Sensor Networks refer to the process of determining the location of the networking sensors in the region of interest after initial deployment. In this process, the fact that the dynamic deployments of sensors is effectively made plays a significant role in increasing the coverage rates of WSNs. The optimization of the coverage rates of Wireless Sensor Networks indicates that the targets in the region of interest are optimally covered by deployed mobile sensors and ultimately these targets can be monitored by the sensors. Therefore, the monitoring of the whole area in Wireless Sensor Network's military and civilian applications is possible by the optimum placement of randomly deployed sensors in the region of interest. In this study, a new dynamic deployment approach was developed based on the current meta-heuristic Whale Optimization Algorithm to find a solution to the problem of dynamic deployment of sensors. In order to solve the area coverage problem of Wireless Sensor Networks, the dynamic deployments of mobile nodes, the initial deployment of which was made randomly, was made by the developed approach using the Binary Detection Model. This approach was compared with the Maximum Area Detection Algorithm based on Electromagnetism-Like in the literature, and the performance of Wireless Sensor Network at coverage rates was measured. Simulation results have demonstrated that the approach developed for the area coverage problem is more effective and can be suggested with respect to the number of mobile sensors deployed and the reached coverage rates of the network.
