Summary:A wireless sensor network consists hundreds or thousands of sensors with limited computing power and memory, which give the information from the environment and then analyze and process the data and also send the sensed data to other nodes or basic stations. In these networks, sensing nodes have a limited battery to provide the energy. In these networks, energy is considered as a challenging problem, researchers decided to propose a new algorithm based on the gravitational search algorithm to prolong the network lifetime and achieve maximum coverage of target area. Performance of the proposed algorithm is evaluated through simulations and compared with GA algorithm. Experimental results show that the proposed algorithm has more appropriate sensor selection. In fact, the total coverage increased by 2% and researchers have 5% more alive sensors in the network when reached to the coverage threshold.
