The optimization of the coverage rate of the entire field of interest in terms of active surveillance of critical regions in military and civil environments determines the efficiency of the Wireless Sensor Networks (WSN) in the area. The coverage problem in WSNs is one of the critical factors that have determined the effective coverage of the area by the sensor nodes. The purpose in coverage problem, which is classified as area coverage and target coverage in the literature, is to ensure that the entire area or deterministically-specified targets in the area are effectively covered by the distributed nodes. In accordance with this purpose, an optimum solution can be found for the coverage problem in WSNs by performing the optimum dynamic deployments of sensor nodes in the field of interest.
In this study, an attempt to optimize the coverage rate of the network was made according to the Probabilistic Deployment Model using heterogeneous nodes consisting of mobile and static nodes by taking into account the area coverage problem. For this purpose, a new dynamic distribution algorithm approach was developed for WSNs based on Electromagnetism-Like (EM) algorithm which is meta-heuristic. The developed approach was compared with the OSDA-EM in the literature, and the performance and effectiveness of this method were measured. Simulation results indicated that the developed method produced optimum results in terms coverage rate and convergence rate of the nodes in the solution of the probabilistic coverage problem of the entire area and that it could be proposed.
