Abstract

Frequency-domain contention is a new paradigm of contention that has been proposed to enhance the performance of OFDM wireless networks. In this paper, we demonstrate how frequency-domain contention schemes would fail in a wireless local area network (WLAN) due to the existence of nodes that are hidden from each other. In addition, we propose a new MAC protocol, which is called EFDC (enhanced frequency-domain contention), that solves the failure problem without sacrificing performance in a WLAN. Simulation is used to evaluate and compare EFDC to the T2F (time-to-frequency) protocol and IEEE 802.11 contention method. The results show that EFDC achieves higher performance in terms of throughput and delay.
