A Service/Device Differentiation Scheme for Contention-Tone-Based Wireless LAN Protocol
A contention-tone-based wireless local area network (WLAN) protocol uses out-of-band signaling for contention resolution to achieve efficient medium access. It is shown that such a protocol can operate at near-optimal channel utilization in the medium access control (MAC) layer. This paper addresses the QoS design of a contention-tone-based WLAN protocol and demonstrates near-optimal operation. While the solution incurs additional cost for busy-tone hardware and spectrum, given its near optimal performance, it has the potential to influence future MAC protocol design should busy-tone approach becomes widely acceptable.
