ZigBee hybrid routing algorithm for network energy optimization based on node cluster label

For the problem that the existing ZigBee hybrid routing algorithms have serious energy consumption of the network, ZigBee hybrid routing algorithm for network energy optimization based on node cluster label is proposed. Utilizing the node cluster label, node judges whether the destination node is in the same cluster. The proposed algorithm employs the improved AODVjr (Ad hoc On-demand Distance Vector junior) and tree routing algorithm based on neighbor tables respectively between clusters and within clusters to reduce the energy consumption of network. Besides, the proposed algorithm can control the transmission range of RREQ (Route Request) packets through setting the maximum transmission hops of RREQ packet reasonably in the process of routing discovery. The simulation results show that the proposed algorithm can effectively reduce the routing overhead ratio and increase residual energy ratio of the network.
