Abstract: This paper proposes TDMA-EC, a novel energy-conserving and collision-free media access control protocol based on TDMA principle. Through assigning separate time slots for neighboring nodes and resolving the "hidden terminal" problem, TDMA-EC performs well with collision avoidance and achieves better energy-efficient performance compared to contention-based protocols. Meanwhile, TDMA-EC schedules receiving and transmitting periods according to node's position in the spanning tree of network, which also guarantees end-to-end latency with less jitter. Simulation results show that TDMA-EC achieves both energy conservation and lower latency compared to SMAC and DMAC.
