QoS Provision for Video-Streaming Applications over Ad Hoc Networks

Feasible video-streaming applications require some end-to-end quality of service (QoS) guarantees from the underlying transmission networks. On the other hand, providing end-to-end QoS over mobile ad hoc networks (MANETs) poses a specially challenging problem because of the inherent dynamic characteristics of these networks. In this paper we propose a cross-layer QoS-provisioning algorithm that uses information collected at different layers of the network's protocol stack. Besides, we exploit the multipath characteristic of the dynamic source routing (DSR) protocol to provide for multiple source-to-destination node-disjoint and loop-free paths. The proposed algorithm seems to improve the performance of video-streaming applications over ad hoc networks
