Comparative Performance Evaluation of Ad-hoc on Demand Distance Vector Routing (AODV) and Optimized Link State Routing (OLSR) Protocol for Mobile Ad-hoc Networks in NS-2

Some years before Mobile Ad hoc Networks are not so popular. After some period of time wireless mobile network are very popular due to its unique features. Mobile Ad hoc Network is the one of the branch in wireless networks is shortly known as (MANETs). MANET is a collection of available communication devices or nodes that wish to communicate without any fixed infrastructure or pre define organization of available links. This MANETs research program has mainly focused on developing an efficient routing mechanism in such a highly dynamic and resource constrained network [2]. All routing protocols have assumed to be a trusted and safe for environment. This comparative performance evaluation project work is related to various Mobile Ad hoc Networks (MANETs) routing protocols such as Ad-hoc on Demand Distance Vector Routing (AODV), Dynamic Source Routing (DSR) and Optimized Link State Routing (OLSR). On the bases of different routing protocols as mention earlier we can stimulate using network simulator software which generate different graph as result. And then see comparative analysis effects on routing protocol parameters for Mobile Ad-hoc Networks (MANETs) on the bases of various simulation environments such as area, number of node, testing field, traffic load etc. Following parameters are considered for comparative performance evaluations are Routing Overhead, End-to-End Delay, Scalability and Throughput. This comparative performance study mainly performed between Ad-hoc on Demand Distance Vector Routing (AODV) and Optimized Link State Routing (OLSR). This above mentioned work shows that which routing protocols is best among them and study the graphs obtain in Network stimulating software (NS-2) for Mobile Ad-hoc Networks (MANETs) on the bases of comparative performance evaluation parameters. AODV and OLSR comparison gives the result, which routing protocol is superior among them using NS-2 and this work concludes as a result.
