Abstract

This paper represents the design, feasibility evaluation and performance validation of concurrency-based coordination mechanism (CCM), a novel cross-layer protocol that can coordinate among nodes effectively to avoid data packet interference in wireless local area networks (WLANs), achieving higher throughput compared to 802.11 standard and other state-of-the-art protocols. The design of CCM contains OpenCCM which is based on the architecture of software defined network to schedule the transmissions in both the uplink and downlink directions centrally to maximize transmission concurrency. It also contains an interference-resistant mechanism in the physical layer that can make the control message transmitted with the data packet simultaneously to eliminate the coordination overhead. Experiment results with USRP2 demonstrate the feasibility of the interference-resistant mechanism, and the simulations by ns-2 show that CCM can outperform other protocols significantly.
