Desirable features of routing protocols for Mobile Ad Hoc Networks (MANETs) include ability to adapt to changing network conditions due to mobility and provide quality control mechanisms during the life time of a route. Current routing protocols that provide Quality of service (QoS) for MANETs have proposed routing based on a single QoS metric. This paper proposes a QoS aware source initiated ad-hoc routing protocol (QuaSAR) that adds quality control to all the phases of an on-demand routing protocol. QuaSAR gathers information about battery power, signal strength, bandwidth and latency during route discovery and uses in route choosing. Additionally, our approach has proactive route maintenance features in addition to the reactive maintenance. We conducted simulation experiments using ns-2 network simulator and compared our results with Dynamic Source Routing (DSR). Our performance results demonstrate that our technique has increased throughput and packet delivery ratio.
