In this paper, the authors introduce a PWTMCP (Predictive-Wakeup Tree-based Multi-Channel Protocol) which is a new pattern multi-channel protocol in combination with the traditional TMCP and duty cycling power control technology. Firstly, it divides the wireless sensor networks into several sub-trees based on the top of base station and allocates a channel to each sub-tree, then information flows transmit along the corresponding sub-tree, which eliminates the interference between the tree and avoids the time synchronization problem. Secondly, it uses duty cycling mechanism, which makes the sender accurately predict the receiver's wake up time, thereby reducing the energy consumption of sensor nodes.
