Abstract

An area of active research right now is ad hoc mobile networking. They can be utilized in agriculture as wireless sensor networks to monitor and regulate environmental parameters. The purpose of this paper is to assess how well the QoS-enabled AODV protocol, the protocol used in these Ad hoc networks, performs. Its performance is assessed by comparing it to the standard AODV protocol. Quality of Service, or QoS, is an acronym. Through the addition of extensions to Route Discovery messages that are related to bandwidth estimation, the research has suggested some improvements to the AODV protocol to provide QoS. Three parameters—Traffic Rate, Node Speed, and Mobile Node Pause Time—have been the focus of this paper. Average end-to-end delay, packet delivery ratio (PDR), normalized overhead load (NOL), and throughput are the performance metrics used for evaluation. Regarding these parameters, the AODV protocol's performance for both QoS and Non-QoS is assessed.

Key words: Ad hoc networks, AODV, bandwidth estimation, quality of service.
