    Investigating the performance of selected MANET routing protocols
    (University of New Brunswick, 2015) Ayansiji, Oluwatola; Pochec, Przemyslaw; DeDourek, John
    A mobile ad hoc network is a dynamic and autonomous system of self-organized nodes operating without infrastructure support. MANET’s topology is dynamic and can change rapidly because nodes move constantly, making the properties of such a network difficult to predict. To facilitate communication among active nodes on the network, a routing protocol is used to determine routes for forwarding data packets. A routing protocol plays an important role for the overall performance of MANETs. In this report we investigate and compare the performance of three well known routing protocols DSR, AODV and DSDV by using a number of performance metrics including the hop count, delivery ratio, end to end packet delay and node utilization. The report also discusses and analyses the impact of hypothetical Denial of Service security attacks on MANETs. The performance analysis is done using the simulation tool NS2. The experiments show that on-demand protocols AODV and DSR seem to outperform proactive protocols like DSDV.
