Abstract
In this paper, a new protocol named Modified Cooperative Access with Relay’s Data (MCARD) for wireless local area networks is proposed. MCARD gives remote stations chance to send their information by using intermediate stations (relays) to Access Point. In the MCARD, a relay and source stations send their information simultaneously to the access point and relay station, respectively, using a smart antenna technique. A uniform circular array of 12 half-wave dipole antenna elements is considered to control the array beam-forming of both relay and source stations. Analytical and simulation results show that MCARD can significantly improve system quality of service (QOS) in terms of throughput and delay under ideal channel conditions.
