A wireless sensor network transfers the data from one node to another node as well as node coverage, and then neighbor location can be identified. In WSN the collisions were avoided and the data's are transferred in efficient manner. To predict the life time of wireless sensor networks before their installation is an important concern. ZigBee is an emerging worldwide standard for Low-Rate Wireless Personal Area Networks based on the IEEE802.15.4-2003 networks (LRWPANs). The IEEE 802.15.4 standard is specifically meant to support long battery life time. Finding out useful metrics to design reliably sensor networks is important concern.
