Minimal Global Hops Algorithm for Energy Balancing in ZigBee Hierarchical Network
Low power consumption is one of the most significant property and pursuing object for ZigBee networks. Because of the multi-hop mechanism in wireless communication, the nodes are always uneven used from the overall perspective, and some devices may exhaust their power quickly. This will result in the potential network segmentation and badly affect the performance. A minimal global hops (MGH) algorithm for energy balancing in ZigBee hierarchical network is proposed in this paper. When some node has low battery, the network structure will be considered in choosing the substitution device to minimize the transmission paths via modified nodes in MGH. This scheme may reduce the power consumption in low battery nodes, as well as lower the cost of topology changes. The simulation result shows that MGH could effectively preserve the cost in low power nodes.
