The ZigBee tree routing is wide used in several resource restricted devices and applications. Since it doesn't need any routing table and route discovery overhead to send a packet to the destination. But the ZigBee tree routing has the elemental limitation that a packet follows the tree topology. Therefore, it cannot provide the optimum routing path. The shortcut tree routing protocol that provides the close to best routing path also as maintains the advantages of the ZigBee tree routing like no route discovery overhead and low memory consumption.
