SIMULATION COMPARISON AND ANALYSIS OF NETWORK THROUGHPUT IN DSDV AND AODV AND DSR MOBILE ADHOC NETWORK PROTOCOLS

Abstract

Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The infrastructureless of this networks and frequent topology changes increase the need to routing strategies to be implemented in order to provide efficient end-to-end communication. Several routing protocols are proposed, they are mainly classified as proactive, reactive and hybrid routing protocols. In this paper, we simulate a proactive routing protocol (DSDV) and two reactive routing protocols (AODV and DSR) using the famous simulator NS2. We conducted some tests for each routing protocol focusing on the throughput. This metric was tested versus the node's velocity, the network load and the traffic type.
