Wireless sensor networks consist of large number of tiny, battery operated sensors and each has the ability to collect process and store the environmental information as well as communicate with other sensors. A wireless senor network has its application in environmental monitoring, Nuclear, Biological and Chemical (NBC) attack detection, object tracking, industrial automation, and home automation. For a sensor network to operate successfully, the sensors should maintain both sensing coverage and network connectivity. The deployment of sensors on the given field is an important issue that affects wireless sensor networks.
