Abstract

This article describes the Priority Based Multiple Access (PriMA) protocol, a new medium access control (MAC) protocol for single-channel ad-hoc networks. Unlike previously proposed protocols, PriMA takes into account the QoS requirements of the packets queued in stations to provide each station with a priority-based access to the channel. The direct support of PriMA for ad-hoc routing is that when some stations act as hubs in the routing structure and route packets for other stations besides their own, they can have high priorities and obtain larger share of bandwidth. Simulation results show the potential benefits that PriMA brings about to ad-hoc networks, and confirm PriMA as an initial step towards QoS provision in ad-hoc networks.
