Abstract
Routing protocols have an important role in any Mobile Ad Hoc Network (MANET). Researchers have elaborated several routing protocols that possess different performance levels. In this paper we give a performance evaluation of AODV, DSR, DSDV, OLSR and DYMO routing protocols in Mobile Ad Hoc Networks (MANETS) to determine the best in different scenarios. We analyse these MANET routing protocols by using NS-2 simulator. We specify how the Number of Nodes parameter influences their performance. In this study, performance is calculated in terms of Packet Delivery Ratio, Average End to End Delay, Normalised Routing Load and Average Throughput.
Highlights
Mobile Ad Hoc Network (MANET) is very used
There is no work in our knowledge in the literature which deals with these five MANET routing protocols by considering the variation of Number of Nodes parameter
To analyze routing protocols (AODV, Dynamic Source Routing (DSR), Destination Sequenced Distance Vector (DSDV), Opitmized Link State Routing (OLSR) and DYMO), we have focused on four performance metrics for evaluation which are Packet Delivery Ration, Average End to End Delay, Normalized Routing Load and Average Throughput
Summary
Mobile Ad Hoc Network (MANET) is very used. A network of type MANET is a group of mobile stations sharing a radio transmission and they do not have any fixed centralized administration. Mobile stations in MANET exchanges messages with each other in a multi-hop manner. Implementing the routing protocols is the main goal of the MANETs. Implementing the routing protocols is the main goal of the MANETs For such implementations concepts of game-theoretic approach, dynamic control approach, information-theoretic approach, or ad hoc networks routing-based approach has been applied [2]. Four essential functions are to be designed by the routing protocols: channel assignment, packet routing, network topology, scheduling and maintaining network connectivity. Routing protocols in MANETs are implemented with some basic objectives that are minimum control overhead, dynamic topology maintenance, multi-hop routing, loop prevention and minimum processing overhead [3].
