The invention relates to a wireless sensor and actuator network technology, especially the ribbon sensor network topology control method for an adjustable power, the difference is that: the method comprises the following steps: Step 1), the stage of information collection: located by the zonal area sensor node is located in the centre of the sensor network node from the near to the distant strip in the area of sensor nodes are initiated, and the channel quality parameters of communication of neighbor nodes, the initial topology connection graph; step 2), the stage of topology optimization: each sensor node distributed computing its connection with the priority of each neighbor node, topology optimization parameters, determine the priority path node sending data packets; step 3), emission power control: each node according to the topology optimization of topology optimization parameters obtained by stages, the sink node open Starting from the near to the distant power control, thereby reducing communication interference, reduce energy consumption.
