The invention discloses a control node in wireless sensor network, the complex task of cooperative processing methods, which mainly comprises the steps of sensor nodes in the work area, the location information of each node are known, the perception of the perceived complex tasks of tasks are described and decomposed into several sub tasks, sensor nodes broadcast the message requires all the nodes in the working area to return to their ID number, location information and energy information, sensor nodes based on the energy from large to small order of nodes sorting, analysis of two node and node angle between the selected node to meet the requirements as the control node, control node according to the position of the working area is divided into several the sub working area, and the number of sub working area and the number of sub tasks are equal. The invention can be applied to wireless sensor network communication, thereby improving the efficiency of complex task cooperative processing and saving network energy.
