A power quality online monitoring system oriented ZigBee routing optimization strategy.

For ZigBee Cluster-Tree routing protocol in the power system applications existing not optimal routing and not real-time problems, the actual demand from on-line monitoring power quality of substation point of view, considering hops, link busy status and the residual energy, a ZigBee Cluster-Tree improved routing algorithm is proposed, calculating the hops of all neighbor nodes to the destination node and introducing an alternative node. Several NS2.34 simulation experiments show that the improved routing optimization algorithm reduces the number of hops and end to end delay, improves power quality monitoring in real time, saves overall network energy consumption, and prolongs the network life cycle.
