Reservation and grouping stations for the IEEE 802.11 DCF

Abstract

In this paper, we propose a novel contention-based protocol, called Reservation with Grouping Stations (RGS) for the IEEE 802.11 Distributed Coordination Function (DCF). In the proposed RGS scheme, stations are grouping into the active group, the ready group, and the idle group. Furthermore, stations announce the next frame's backoff counter beforehand. The proposed scheme is compared with the DCF and another scheme in the literature, and simulation results show that the proposed scheme is the best among these three schemes. © IFIP International Federation for Information Processing 2005.
