Aiming at the premature paralysis of network problem, which is caused by energy consumption imbalance of nodes in ZigBee, a weight-based clustering hybrid routing algorithm is proposed. From the viewpoint of energy, the algorithm considers the status of the node and network, selects cluster head according to the weights, and achieves energy balanced clustering of heterogeneous nodes. In the cluster, we adopt cluster-Tree routing algorithm to implement optimization of local network. And among the different clusters, we adopt the AODVjr algorithm to reduce the latency of communication between the different clusters and routing overhead by controlling the flooding direction of RREQ. The simulations reveal that the improved algorithm effectively reduces the mortality rate of nodes and decreases energy consumption in the network, balances the network energy load, and prolongs the lifetime of network.
