Distributed QoS guarantees for realtime traffic in ad hoc networks

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

In this paper, we propose a new cross-layer frame-work, named QPART (QoS Protocol for Ad hoc Realtime Traffic), which provides QoS guarantees to real-time multimedia applications for wireless ad hoc networks. By adapting the contention window sizes at the MAC layer, QPART schedules packets of flows according to their unique QoS requirements. QPART implements priority-based admission control and conflict resolution to ensure that the requirements of admitted realtime flows is smaller than the network capacity. The novelty of QPART is that it is robust to mobility and variances in channel capacity and imposes no control message overhead on the network.
