AODV, DSDV and OSLR Protocols Performance over MANET

Abstract

As each mobile node of a MANET is treated as an autonomous peer, and the random mobility patterns of the mobile nodes need to be analyzed to obtain the performance of the continuously changing topology network. Many mobility models are designed and analyzed to the real-world scenarios with limited communication resources. MANETs belong to Wireless Networks where the nodes communicate with each other in a multi-hop fashion without any centralized control. Such network is infrastructure less, resource constrained, works in dynamic topology to provide communication. As routing performs a crucial role for obtaining the path from source to the destination, so mobility modeling and control makes the topology more challenging. Here, in this paper we have compared three routing protocols with AODV, DSDV, and OLSR for the ten samples by varying number of nodes and number of packets sent on the network and obtained the cases where these protocols perform best. OLSR performs well in the less crowd networks than the AODV and DSDV. AODV performs better than when the number of nodes is less than five in our sample.
