Comparative Study and Performance Analysis of DSDV, OLSR, AODV, DSR and MAODV Routing Protocols in MANETs

Mobile Ad-Hoc Network (MANET) is a wireless network without infrastructure and decentralized network which need a robust dynamic routing protocol and it is becoming an important concept of modern communication technologies and services. There are various routing protocols available for MANETs. In this work, we focus on the most popular ones are Destination- Sequenced Distance Vector (DSDV), Optimized Link State Routing(OLSR), Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Multicast Ad Hoc On-Demand Distance Vector Routing Protocol (MAODV) routing protocol. This paper is an attempt to study, analysis and compare these five routing protocols on the basis of various performance metrics such as throughput of received packets, throughput of dropped packets, packet delivery ratio, end to end delays, jitter and normalizes routing load .This performance evaluation have been perform under different environments. The simulation results indicate that none of the routing protocols we selected have shown best performance in all the six different performance metric. Therefore, the efficiency of a network can be achieved by choosing the best suitable protocols based on the network requirement.
