Abstract: ZBR is the most popular routing protocol in ZigBee network currently, but in some cases, it is not very efficient. In this paper a new improved ZBR is proposed which add the network address range field of neighbor node in the neighbor table. So the node can distinguish whether the destination node is the descendants of its neighbor. Compared with the previous protocols OI-ZBR, NI- ZBR and ZBR in NS-2, NP-ZBR shows its merits in the average hop, end to end delay and the first packet delay.


Keywords: ZBR, NS-2 simulation; Routing protocol, Neighbors perception.
