ZigBee is an emerging standard for the low cost, low power and low rate wireless networks. ZigBee standard specifies two routing protocols: a tree routing protocol and a route discovery protocol similar to AODV. The second one discovers the optimal path by flooding route quest command frame, which wastes significant amount of bandwidth and energy. This paper proposes a novel route discovery method based on limited flooding in ZigBee networks. The tree routing information is utilized to obtain the flooding radius, which limites the flooding in a bounded region of the network. Simulation results show that the proposed method can effectively reduce the communication overhead.
