The invention discloses a wireless sensor network data reliable aggregation method based on a continuous-collecting single-transmitting model. The method comprises data transmission mechanism connection establishing, data transmission congestion control and data transmission selective retransmission. When establishment of the data transmission mechanism connection is started, sensor nodes put forward data transmission requirements to data aggregation nodes, data transmission control information is transmitted incidentally in a link establishment process, and data source node control information cost is reduced. After connection establishment is completed, the method turns into a data transmission phase. The sensor nodes and the data aggregation nodes respectively carry out network congestion control through NACK, and the loss of a large amount of transmission data caused by network congestion is avoided. When data losing or transmission errors occur in a data transmission process, the sensor nodes carry out selective and preferential retransmission of the data, and reliable and efficient transmission of the data is guaranteed under the condition of not increasing network loads.
