Abstract
Recent growing widespread attention given to mobile communications has led to rapid growth in research and development involving mobile wireless networks. The need for easy deployment and self-configured networks makes mobile ad-hoc networks (MANETs) an attractive choice for various applications. However, due to its dynamic nature and imprecise network state information, there are many challenges which need to be addressed including Quality of Service (QoS) routing. Numerous approaches have been proposed including QAODV. It is proposed to enhance one of the existing routing protocols for MANETs namely AODV (Ad-Hoc On- Demand Distance Vector). Q-AODV adds necessary new fields to cater QoS provisioning requirements. This paper aims to conduct evaluation study on AODV and QAODV approaches. Some new fields are added with AODV to form QAODV to avoid resource wastage as well as maximize utilization of network capacity. In order to identify the pros and cons of both methods, NS-2 Simulator is used to conduct the simulation study. Throughput, End-to-end delay, Packet Delivery Ratio (PDR) and Normalized Overhead are the selected evaluation metrics. Our experiments study the effect of number of mobile nodes, mobility and traffic load.
