A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, pressure, motion or pollutants. WSN consists of large number of small size sensors which they can sense the environment and communicate with each other and processing the sensing data. Because of the deployment nature of the Wireless Sensor Network once it deployed users can't recharge the battery. So energy conservation is one of the important factors. Under this constraint maintaining good coverage and connectivity is also important factor of designing WSN .In this paper, the authors propose a new sleep scheduling algorithm, named EC-CKN algorithm will reduce the energy consumption and to prolong the network lifetime.
