In many sensor network applications the major traffic pattern consists of data collected from many source nodes to a sink through a tree. In this paper, we propose S-Non Bcn based on nonbeacon-enabled (Non Bcn) mode of IEEE 802.15.4, an energy-efficient and low-collision MAC that is designed and optimized for such data gathering trees in wireless sensor networks. S-Non Bcn uses staggered sleep mechanism to save energy. It also adopts two mechanisms to reduce serious collisions caused by staggered sleep mechanism. The simulation results reveal that S-Non Bcn outperforms Non Bcn in energy consumption, end-to-end packet loss rate and end-to-end good put.
