In Ad-Hoc network a group of wireless mobile nodes cooperate with each other by routing of packets. So it is necessary to design a wireless network which gives the best performance by suitable protocol selection and path routing. The selection of protocol should be suitable in terms of data integrity as well as data delivery. Hence performance evaluation of protocol is a major issue before selection of a routing protocol. In this paper our aim is to analyse the performance matrices including end to end delay, jitter, packet loss and packet delivery fraction of multi hop network by simulation. Performance evaluation of wireless ad hoc network routing protocols specially Ad-hoc On Demand Distance Vector (AODV), Optimized Link State Routing (OLSR), Destination Sequenced Distance Vector (DSDV) have been completed using NS-3 Simulator. After simulation we have found that OLSR routing protocol gives the best result comparison to AODV and DSDV in large and dense network. Index Term—DSDV, AODV, OLSR, Performance Evaluation, and Ad-Hoc Network Routing Protocols. I. INTRODUCTION Wireless ad hoc network is a self-organised, self- configured collection of nodes that communicate over wireless links without help of any base station or an access point nodes work as both host and specialized router. The infrastructure less interconnection of the nodes through routers can be arranged dynamically in Ad-Hoc network. There are lot of work has been completed in improvement of routing protocols in Ad- Hoc network mainly in WSNs, MANETs, VANETs and WMNs[14].In Ad-Hoc network routing protocol should consider various function like packet routing ,channel assessment, transmission scheduling ,maintaining network connectivity and determination of network topology. Primary goal behind the development of routing are minimum processing overhead ,multi-hop routing capability ,dynamic topology maintenance ,loop prevention and minimal control overhead [13].In Ad-Hoc routing protocol performance depends upon the various factor like node mobility which leads to link failure several time ,quality of service(QOS) support, network size and traffic intensity. The performance sometimes also depends upon the behaviour of network as well as type of work in that environment [12].Ad-hoc network can be deployed quickly with minimal overhead. This nature makes suitable for emergency use such as in earthquake, in disaster areas or where building infrastructure is expansible in conference room where people need to share the information. Ad-hoc network is also as option for connectivity to internet by co-operation of people. Choosing a suitable protocol is very important to deploy an ad-hoc network. The main objective of this paper is simulation analysis of routing protocols to observe and evaluate various factors without using resources and with minimum effort that may influence the performance of network. We emphasized on analysis of the performance matrices including jitter, end to end delay, packet loss and packet delivery fraction of multi-hop network by Destination Sequenced Distance Vector (DSDV), Ad-hoc On Demand Distance Vector (AODV) and Optimized Link State Routing (OLSR) routing protocol by using NS-3 simulator. Simulation analyses are also useful for understanding behaviour of protocols and to know the weakness for further improvements. Remaining part of this paper is organised as follows: Section-2 gives related work, section-3 gives overview of Ad-Hoc routing protocols, section-4 gives simulation environment and section-5 gives performance analysis of protocols. Lastly conclusion and future work follows in section-6.
