Abstract :
A QoS-based multiple access (QMA) protocol for multi-hop ad hoc networks is proposed. In this paper, the traffic is divided into real-time and non real-time traffic. According to the protocol, nodes with real-time traffic have higher priority to access channel than those with non real-time traffic by broadcasting forecast bursts (FB) in earlier contention slots. Meanwhile, traffic is scheduled according to its delay and the earliest deadline first (EDF) principle. Through simulations, it is shown that the QMA protocol outperforms Carrier Sensing Multiple Access with Collision Avoidance (CSMA/CA) protocol, and it can provide QoS guarantees in multi-hop networks.
