They can be used in agriculture for monitoring and control of environmental parameters in the form of wireless sensor networks. The aim of this paper is performance evaluation of protocol of these Ad hoc networks i.e. QoS-enabled AODV protocol. The performance evaluation is done by means of its comparison with normal AODV protocol. QoS stands for Quality of Service. The research proposed some enhancements to the AODV protocol to provide QoS by adding extensions to Route Discovery messages, related to bandwidth estimation. This paper focuses on three of the parameters namely Traffic Rate, Speed of nodes & Pause Time of mobile nodes. For evaluation purpose the performance metrics used are Average end-to end Delay, Packet Delivery Ratio (PDR), Normalized Overhead Load (NOL) and Throughput. Performance of the AODV protocol for QoS as well as Non-QoS is evaluated with respect to these parameters.

Keywords: Ad hoc, AODV, Bandwidth Estimation

I. INTRODUCTION

In an Ad hoc mobile network, every node in the network carries its own router with it, and all nodes cooperate in carrying traffic. The whole philosophy of the Ad hoc networking model is a radical departure from the highly structured and frequently hierarchical models employed for both local area and wide area networking, currently in use. The range of possible situations in which Ad hoc networking can be exploited is huge. What mature and robust Ad hoc networking offers is virtually universal connectivity, limited only by the link performance and routing delays of the participating nodes, and their
