Quality-of-service (QoS) is a desirable feature for mobile ad hoc networks (MANETs) due to the growth of multimedia applications. However, the mobile nature and dynamic topology of MANETs make it difficult to provide QoS assurance in such networks. In this paper we propose a QoS routing protocol based on AODV (QS-AODV), which creates routes according to application QoS requirements. A local repair mechanism is used to improve the packet delivery ratio. It is shown that QS-AODV provides performance comparable to AODV under light traffic conditions. In heavy traffic, QS-AODV provides higher packet delivery ratios and lower routing overheads, at a cost of slightly longer end-to-end delays. The effects of mobility on performance is also presented.
