By analyzing the data transmission Collisions for wireless sensor networks, due to the shortage of energy efficiency and latency in MAC protocol, we propose a distributed TDMA scheduling protocol based on coloring algorithm (TDMA-CA), which uses spatial reuse of transmission channel. It allocates different colors for conflict nodes in the networks, and arranges distinct slots for data transmission for each color by TDMA scheduling. Simulation results show that TDMA-CA is better than SMAC in terms of both energy efficient and latency.
