As the advanced information acquiring technology, wireless sensor networks are being applied in more and more areas. Data aggregation is the effective information processing to solve the energy saving problem of WSN (Wireless Sensor Network). Most existing data aggregation algorithm discuss fusion problem in the scene that the number of nodes is fixed. However, the amount of data transmitted is directly proportional to the number of nodes. Hence the appropriate strategy should be that the number of nodes is alterable under the satisfaction of performance. In this paper, sequential detection is applied in data aggregation for wireless sensor network. And the mathematical model is established. Considering the fading problem of wireless channel and the characters of physical layer, WSN data aggregation with sequential detection (WDASD) is proposed. The characters of WDASD are tested by simulations. In the end, a cross-layer scheme is proposed and simulation test is made to validate it.
