Both the hierarchical routing based on address allocation and the routing method based on routing discovery are available in ZigBee network. In the strategy ，the node chose the routing method self-adaptively on the basis of the change of node mobility. Nodes recognized the mobility variety through the change of parameters in neighbor table to avoid the extra network load. The simulation results showed that the routing strategy based on node mobility ，compared with original single routing schemes ，had better routing effi- ciency and improved the routing performance in ZigBee network.
