A QoS approach to hybrid TDMA with heuristic traffic shaping for time critical application environments

Abstract

QoS/HyTDMA-HTS is a new collision-free MAC sublayer protocol which provides the well known HyTDMA-HTS protocol with QoS extensions which enable it to offer quality services in demanding environments with critical applications for which time sensitivity is a key issue. QoS/HyTDMA-HTS can operate in bursty traffic networks, successfully regulating QoS parameters of hosts running real-time services even under high traffic loads, while at the same time, the traffic shaping techniques which it employs, prevent other hosts from sending large amounts of traffic and monopolizing the available bandwidth.
