An Efficient Backbone Aware Shortest Path Selection Protocol in Zigbee Wireless Networks

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. in a very tree-structured ZigBee wireless network, nodes near the basis of the tree (i.e., hot-spot nodes) could exhaust their power sooner than those distant from the basis attributable to serious hundreds on packet forwarding. This hot spot downside is inherent in tree-structured networks and should demand additional energy to live through failures of hot-spot nodes. The backbone-aware topology formation (BATF) theme is planned to alleviate the hot-spot downside. BATF utilizes power-rich nodes to create a backbone tree that doesn't suffer from the new spot downside. To prolong the period of time of a ZigBee network and improve its knowledge assortment capability introduced a backbone-aware topology formation (BATF) theme.
