The rapid advances in processor, memory, and radio technology have enabled the development of the distributed networks consisting of small, inexpensive nodes that are capable of sensing, computation, and wireless communication. In the future, sensor network is envisioned to revolutionize the paradigm of collecting and processing information in diverse environments. However, the sensor has the severe energy constraints and limited computing resources. Therefore, present major challenges are to gather information with power saving method.

Under the described assumption, we propose the tree design method which equialize the energy dispirited by each sensor node and minimize the total dispirited energy, such that the lifetime is maximized.
