Abstract Combining the delivery of query messages with the setting up of data transmitting structure, a novel distributed data collection scheme for wireless sensor network——TBDCS (Tree Based Data Collection Scheme) is proposed in this paper. Using a flooding avoidance method, TBDCS sets up a tree with minimum intermediate nodes, which are also data aggregators when sensor nodes send data back. Theoretical analysis proves that TBDCS changes neither the network connectivity nor the shortest path’s length between the sink and any other sensor nodes. Simulations show it significantly reduces the traffic and achieves longer system lifetime.
