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
