As regard to the case of extending the lifetime of ZigBee network, the definition of node's boundary is proposed. First, all the information for node's boundary is stored when ZigBee network is built. Then, the packet between the nodes which are in the node's boundary is transferred directly. The packet between the nodes whose boundaries are adjacent is transferred through the node with maximum energy. The experimental results show that the new algorithm can efficiently extend the lifetime of ZigBee network.
