Summary:Every station within carrier sense zone must keep quiet till the end of transmission which originates that carrier sense zone. We observe futile transmission attempts into this carrier sense zone. With thorough understanding of transmission zone, carrier sense zone, interference zone and corruption zone through equations we derive, we propose alternative attempts which effectively remove inefficiency in the multi-hop WMNs (wireless mesh networks). We show the gain of alternative attempts with analytic approaches and prove the performance improvement with extensive simulations. Our proposed MAC scheme is compatible with the existing 802.11 MAC and requires only subtle modification on commercially available 802.11 devices.
