For the problem of how to improve the transmission performance in wireless sensor networks, the paper proposes a scheme of using different transmission modes for different topology structures. Based on the analysis of two different structures: the tree structure and the network structure by the NS2 simulation software, the delivery rate(packet loss rate), the average end-to-end delay and the routing overhead are analysed for the two different structures, and for the beaconless and beacon-enabled operations. The experimental results show that the different topology structures targeted by different transmission ways really can increase the transmission performance.
