The Internet of things is a network that based on the IEEE802.15.4 wireless communication protocol and transmit data between devices. It contains a big variety of communication technology, considering the advantages of low-power,low-cost and large-capacity, ZigBee technology becomes the best way to solve Wireless Personal Area Network portion of Internet of Things. However, due to the theoretic immaturity of this newborn technology and complexity of its hardware implementation, there are numerous problems need to be solved, such as reduce energy consumption to increase the lifetime of zigbee, this paper propose an energy-balanced algorithm which combine and balance ME-AODV(Multipath Energy Aware AODV Routing)and Cluster-Tree routing algorithms. This algorithm employs ME-AODV and Cluster-Tree routing algorithms in different energy conditions to reduce energy consumption and extend the lifetime of network. The simulation have been performed using IEEE802.15.4,ns-2moudule and simulation results show that the improved algorithm can optimize the energy consumption of ZigBee network compared with original algorithm.
