QoS-aware Routing for Real-Time and Multimedia Applications in Mobile Ad Hoc Networks

International audienceWith the increasing development of real-time and multimedia applications, there is a need to provide bandwidth and delay guarantees. Most of QoS ad hoc network routing protocols select path guaranteeing delay and/or bandwidth. However, they don't consider throughput optimization, which results in a low number of admitted real-time and multimedia flows. In this paper, we propose a cross-layer TDMA-based routing protocol to meet delay and bandwidth requirements while optimizing network throughput. Since in TDMA-based ad hoc networks, slot reservation impacts two-hops neighbors, our routing protocol selects paths with the lowest number of neighbors. To show the effectiveness of our protocol, we present simulations using NS-2

An On-Demand, Link-State, Multi-Path QoS Routing in a Wireless Mobile Ad-Hoc Network

The peer-to-peer multimedia applications have recently generated much interest in wireless network infrastructure with supporting the quality-of-service (QoS) communications. In this paper, we propose a new on-demand QoS routing, namely link-state multi-path QoS routing, protocol in a wireless mobile ad-hoc network (MANET). Our proposed scheme offers a bandwidth routing protocol for QoS support in a multihop mobile network. Our QoS routing protocol determines the end-to-end bandwidth calcu- A preliminary version of this paper presented at EW2002: European Wireless 2002, Feb. 2002, Florence, Italy
