Implementing and Comparing DSR and DSDV Routing Protocols of Mobile Ad-Hoc Networks using NS2 Simulator

Abstract

MANETs consists of mobile nodes that dynamically form a network temporarily without any support of central administration. MANET is a self organized and self configurable network. Moreover, each node in MANET moves arbitrarily, making routing a crucial issue. This paper presents the performance evaluation of Dynamic Source Routing (DSR) and Destination-Sequenced Distance Vector (DSDV) routing protocols based on metrics such as throughput, packet delivery fraction, dropped packets, packet loss, normalized routing load and average end-to-end delay by using the NS2 simulator. DSDV is a Proactive routing algorithm where the mobile node periodically broadcasts an advertisement message which is transmitted after expiration of the timer. DSR is a Reactive routing algorithm where a mobile node of MANET connects or advertises the message only when it is needed.

An Improved OSPF Routing Algorithm Based on Quotient and Granularity Space Theory

“…One of the most important services is routing method since enormous data are transferred and exchanged within the network [6]. Traditional shortest path first (SPF) algorithms such as Dijkstra focus on how to find out a best route which is able to meet the requirement or maximum satisfy the requirement [7][8].…”
