A novel cluster head selection method using energy for ZigBee cluster-tree network

To solve the problem that the cluster heads consume a lot of energy in the cluster tree network, a new method which can balance energy consumption and improve the energy utilization ratio is proposed in this paper. This method employs the existed network address resource to select the reserved cluster head. By this method, the convert of network structure which caused by changing cluster head is also reduced. The simulation result shows that the data transfer rate has been improved and the energy consumption of network has been balanced.
