Extensive Simulation Performance Analysis for DSDV, DSR and AODV MANET Routing Protocols

Mobile Ad-hoc Network (MANET) is a compilation of independent wireless mobile nodes which animatedly forms a temporary network without use of any fixed infrastructure or centralized management. A major anxiety that affects such a network that characterized by dynamically changing topology is the performance, where routing with robustness performance is one of the key challenges in deploying MANET. In this work we concentrate on routing protocols which are widely used in MANET, Destination Sequenced Distance vector (DSDV), Dynamic Source Routing(DSR) and Ad hoc On demand Distance Vector(AODV) routing protocols that are widely simulated in this paper using different scenarios in terms of different Traffic types, constant bit rate(CBR), variable bit rate(VBR) then combining both classes in one scenario to scrutinize the impact of this combination. Routing protocols are analyzed against several performance metrics, Average energy consumption, Average throughput, Normalized routing load (NRL), packet delivery fraction(PDF) and total dropped packets(TDP). Combined traffic results pronounce that DSR and AODV exhibit better behaviors overall the performance metrics examined.
