Performance Analysis of Aodv, Dsr and Dsdv Routing Protocols in Mobile Ad-hoc Network (manet)

A Mobile Ad-hoc Network (MANET) is a collection of wireless nodes that can dynamically form a network to exchange information without using any pre-existing fixed network infrastructure. MANET is a self organized and self configurable network where the mobile nodes move arbitrarily. The mobile nodes can receive and forward packets as a router. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently. For relatively small networks flat routing protocols may be sufficient. However, in larger networks either hierarchical or geographic routing protocols are needed. The protocols have to be chosen according to network characteristics, such as density, size and the mobility of the nodes. MANET does not require any fixed infrastructure, such as a base station; therefore, it is an attractive option for connecting devices quickly and spontaneously. In this three routing protocols AODV (AdHoc On-Demand Distance Vector), DSDV (Destination Sequenced Distance-Vector) and DSR (Dynamic Source Routing Protocol) are compared. Most of the previous research on MANET routing protocols have focused on simulation study by varying various parameters, such as network size, pause times etc. The performance of these routing protocols is analyzed in terms of their Packet Delivery Fraction, Average End-to-End Delay and their results are shown in graphical forms. The comparison analysis will be carrying out about these protocols and in the last the conclusion will be presented, that which routing protocol is the best one for mobile ad -hoc networks.

These systems work with the support of a centralized supporting structure such as an access point. The wireless users can be connected with the wireless system by the help of these access points, when they roam from one place to the other. Recent advancements such as Bluetooth introduced a fresh type of wireless systems which is frequently known as mobile ad-hoc networks. Mobile ad-hoc networks or "short live" networks control in the nonexistence of permanent infrastructure. Ad-hoc is a Latin word, which means "for this or for this only."[1] Mobile ad-hoc network is an autonomous system of mobile nodes connected by wireless links; each node operates as an end system and a router for all other nodes in the network. A wireless network is a growing new technology that will allow users to access services and information electronically, irrespective of their geographic position. Wireless networks can be classified in two types: infrastructured network and infrastructure less (ad-hoc) networks. Infrastructured network consists of a network with fixed and wired gateways. In this work, an attempt has been made to compare the performance of two prominent on demand reactive routing protocols and one proactive routing protocol for MANETs AODV, DSR and DSDV protocols. DSR and AODV is a reactive gateway discovery algorithm where a mobile device of MANET connects by gateway only when Citation: Parul Sharma, Arvind Kalia and Jawahar Thakur (2012) Performance Analysis of AODV DSR and DSDV Routing Protocols in Mobile Ad-Hoc Network (MANET).
