Simulation Analysis of AODV and DSDV Routing Protocols for Improving Quality of Service in MANET

Background: In the past few years, Mobile Ad Hoc Networks have been a popular area of exploration. But, to design a reliable and an efficient routing strategy is still a challenge. A number of routing protocols have been designed to overcome the existing problems and the number is still increasing. Method: In this paper we have simulated and analyzed existing well known routing protocols Ad-Hoc On-demand Distance Vector (AODV) and Distance Sequenced Distance Vector (DSDV) over number of packets and nodes. Various performance criterion used for comparison are end-to-end delay, throughput, and packet loss ratio. Findings: The study shows that AODV protocol outperforms DSDV in terms of QoS parameters such as packet loss ratio, end-to-end delay, and throughput. Improvements: AODV protocol can be further improved by the use of optimization techniques for better path establishment and enhanced QoS.
