A novel QoS-aware routing for ad hoc networks

Abstract

Most routing protocols focus on obtaining a workable route without considering network traffic condition for a mobile ad hoc network (MANET). Therefore, the quality of service (QoS) is not easily achieved by the real time or multimedia applications. To support QoS, this work proposes a QoS-aware routing protocol that incorporates an admission control scheme into route discovery and route setup. A dual-card dual-signal mechanism is adopted to increase system performance. Simulation results show the proposed protocol can more significantly improve packet delivery ratio, throughput (in heavy load), as well as reduce average end-to-end delay than routing protocols without QoS support can.
