To Enhance Routing in ZigBee Wireless Networks
The ZigBee tree routing does not require any routing table and route discovery overhead to send a packet to the destination, so it is widely used in many resource-limited devices and applications. ZigBee is based on IEEE Standard 802.15.4. ZigBee is a specification suite for a high-level communication protocols used to create Wireless Personal Area Networks (WPANs). ZigBee is frequently used in low data rate applications that entail long battery life and secure networking. In ZigBee network, to send the packet to destination it doesn't require any routing table and route discovery overhead.
