Wireless sensor network is an uprising low cost sensor network for sensing, integrating and processing data collected by sensors. It provides a wide area of research as they can be used in various applications (e.g. home, military, security etc.,). Wireless sensor networks are the networks which are inherently prone to errors or faults due to sensitiveness of the sensor nodes. These sensor networks are usually deployed in remote and unattended areas hence the effect of harsh environment, limited resource or some other hardware configuration can make them faulty.
