Recently, wireless sensor networks have attracted a lot of attention. They are being used in many fields like security and surveillance, disaster prevention, agriculture, and traffic monitoring. Such environments may consist of many low cost nodes, each having the ability of gathering, storing, and dealing with environmental information and communicating with neighboring nodes via wireless links. One of the fundamental problems in sensor networks is the coverage problem, which reflects the quality of service which is provided by a particular sensor network and how well a sensor network is monitored or tracked by sensor.
