Overview of ZigBee based WSN

Wireless Sensor Network is the best solution for quick capturing, processing and transmission of critical data. Sensor nodes can be deployed in hostile environment but nodes suffer from low battery power. So, energy efficiency and network lifetime are main concerns in WSN. In order to improve these factors ZigBee plays an important role. Low cost, low data rate features of ZigBee results in low power consumption and makes it useful in wireless sensor networks, increasing life of small batteries of nodes in the network. In this paper, we are dealing with ZigBee based wireless sensor networks.
