Abstract: An energy-efficiency amendatory algorithm is proposed to save limited energy in Wireless Sensor Network (WSN). In this algorithm, a sensor node changes it status according to the threshold of its energy condition. Therefore, the energy consumption in the path with the sensor node consuming most energy could be transferred to other paths in order to reduce the whole energy consumption of the network. Through experiments and analyses the relationship curve between the probability of number of nodes and the amount of data transmission was obtained; the factors that affect this relationship curve were analyzed; the features of the curve and the threshold mentioned above were found. Because of the energy consumption by the algorithm itself, the concept of data gravitation was proposed to reduce the energy consumption. Experiment results show that the algorithm is energy efficiency and the lifecycle of the networks is increased.
