Synchronization Mechanism for Collision and Against Collision in Densely Deployed Wireless LANs
We here propose a novel MAC instead of DCF, SMTC/CI (Semi-synchronous Multiple Transmission Control / Collision Inference), which achieves high fairness and throughputs by inducing effective parallel transmissions with frame capture effect. The radio interference could disturb high-quality communications with fairness, because of the spreading of mobile wireless LANs such as mobile router and tethering nodes. Hence, we need an innovative MAC considering interference among wireless LANs. Frame capture effect is the key factor in order to improve quality of communications in dense wireless LANs. SMTC/CI consults history of frame transmissions in order to infer the effective collisions due to frame capture effect, then maintain superior synchronous transmissions. As a result of our simulation, throughput is improved up to 112% compared with conventional MAC.
