Performance Analysis of MANET Routing Protocols with UDP and TCP under VBR traffic

Abstract

Identifying network quality in Mobile Ad hoc Network (MANET) is very challenging issue because of its decentralization infrastructure and dynamic variation of users. It involves consideration of various parameters: such as transport layer protocol, packet size, number of users and selected routing protocol. In this work we carry out a number of simulations to evaluate the behavior of routing protocols (Proactive and Reactive) in relation of transport layer agents User datagram Protocol (UDP) and Transmission Control Protocol (TCP). The main attention of work is to analyze the behavior with variation of number of nodes. For the work we have selected AODV, DSDV and AOMDV routing protocols and traffic data rate is considered as variable Bit Rate (VBR). Simulations are done by NS2. For results the performance is analyzed with metrics such as throughput, packet delivery ratio and end-to-end delay.
