Performance Analysis of Routing Protocols in Mobile Ad-hoc Networks (MANETs) Using NS2: A Comparative Study of AODV, DSR, and DSDV

MANET stands for Mobile Adhoc Network also called a wireless Adhoc network or Adhoc wireless network that usually has a routable networking environment on top of a Link Layer ad hoc network. A MANET can be defined as an autonomous system of nodes or MSs(also serving as routers) connected by wireless links, the union of which forms a communication network modeled in the form of an arbitrary communication graph. The characteristics of an ad-hoc network can be explored on the base of routing protocols. Simulation can be defined as “Imitating or estimating how actions might happen in a real situation”. It can engage in the complex mathematical modeling, combinations and role playing without the aid of technology. The value deceit in the pacing you under realistic conditions that modify as a result of behavior of others involved, so you cannot expect the sequence of events or the final result. For this purpose we first study and explain these protocols and then we use the Network Simulator – 2.35 (NS2) tool and analysis the performance metrics Packet Delivery ratio, End to End delay, Throughput and Residual Energy.
