Geographic location based STR protocol in Wireless Zigbee Networks
Midhu Venugopal · 2014
Zigbee is the emerging industrial standard for ad hoc networks. Zigbee is expected to be used in wireless sensor networks for remote monitoring, home control, and industrial automation, due to its characteristics such as low data rate, low price, and low power consumption. Since tree routing does not require any routing tables to send the packet to the destination, it can be used in zigbee that have limited resources. Even though the destination is located nearby, tree routing has a major problem that it follows the tree topology to the destination. We propose the shortcut tree routing(STR) protocol to reduce the routing cost of zigbee tree routing(ZTR) by using the neighbor table and also the overhead is further reduced by introducing a concept called geographic location based STR routing. In zigbee tree routing algorithm, it suggest forwarding the packet to the neighbor node if it can reduce the routing cost to the destination. Simulation results show that the shortcut tree routing algorithm with geographic location reduces overhead, route cost and hop count to a large extend than ZTR and as well as STR.
