Wireless Sensor Network is an integrated network which combines information gathering, processing and transmitting. The sensing nodes transmit the information to the sink node, which processes the information then transmit it to the terminal. Coverage control is a primary problem in wireless sensor networks, which reflects the quality of service on WSNs. The goal of
