Abstract

In this paper, we propose a novel routing protocol for QoS requirement in mobile ad hoc networks (MANET) called QoS-Aware Routing (QAR) based on local information. QAR takes bandwidth as the metric of the admission scheme, and considers the capability of the available node and path according to node congestion factor and path congestion factor. We simulate our QAR for nodes running the IEEE 802.11 MAC. Results of our simulations show that the packet delivery ratio increases, and the delay of data packet and energy consumed decrease significantly for both static topology and mobile topology compared with DSR that does not provide QoS support.
