The lifetime of a wireless sensor network (WSN) directly lies in the power consumption of the network. Thus one of the important problems is how to deploy the sensor nodes efficiently to prolong the lifetime of the sensor network. A maximizing lifetime model is proposed by analyzing a line heterogeneous wireless sensor networks which consist of two types of nodes: one is advanced nodes, the other is normal nodes, Based on the theory analysis of the two types of sensor's energy consumption, the allocation proportion between different nodes is calculated, and a maximizing lifetime scheme of node deployment is proposed.
