Taking account of the drawbacks in energy, efficient and low-latency of the most of large-scale wireless sensor MAC protocols, the paper presented ATSP based on clustering. ATSP divided the entire network into some clusters, the protocol constructed a data gathering tree in each cluster. Each round, the cluster head adjusted the time-slot of nodes according to their weighted traffic load in a proper order and frequency,reduced thus the idle listening, and achieved the energy consumption balancing among nodes with a low latency. Simulation results show that the protocol can meet the system requ...
