Routing Selection Strategy Based on Link Failure in ZigBee Networks with Changing Mobility

The hierarchical tree routing and Z-AODV routing are both available in ZigBee specification to meet the requirements in different applications. However, the research on principle and method of routing selection is still underway. Moreover, most research on ZigBee routing was examined in a single network condition, and the variation of wireless environment should be more considered. Aiming at lower power consumption, a routing selection strategy based on link failure in the networks with changing mobility is proposed in this chapter. The algorithm utilized the information in network address and neighbor table of ZigBee devices, to recognize the mobility changing of nodes without any extra communication. The simulation results show the algorithm could reduce the average network load in all the conditions have been tested.
