Distributed flow admission control for real-time multimedia services over wireless ad hoc networks

In this paper, we propose a novel Priority-based Distributed flow Admission Control (PDAC) protocol which adds enhancements to the existing Dynamic Source Routing (DSR) protocol in order to provide Quality of Service (QoS) to traffic flows belonging to realtime and multimedia applications in wireless ad hoc networks. PDAC allows a node to establish and/or discard traffic flows based on the global knowledge of traffic flow priority and available throughput together with the local knowledge of prevailing channel conditions, interference neighborhood, and available transmission rate. The PDAC protocol can also operate in 'cross-layer' architecture that encompasses network and MAC layers in order to provide fairness to higher-priority flows, better channel utilization, and effective resource reservation.
