Scalability Performance of AODV, TORA and OLSR with Reference to Variable Network Size
نویسنده
چکیده
An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any pre-existing network infrastructure. A number of ad hoc routing protocols have been developed during the time, but none of these is able to produce efficient routing of packets in large number of nodes due to their own limitations. Therefore, scalability is an open issue in all routing protocols. In this paper, we presented our observations regarding the scalability comparison of the three MANET routing protocols, Ad hoc On Demand Distance Vector (AODV), Temporally Ordered Routing Protocols (TORA) and Optimized Link State Routing (OLSR) by varying the number of nodes. The simulation is done by using OPNET Modeler 14.5 simulator by taking throughput and network delay as performance metrics. In case of delay AODV and OLSR perform in a similar manner as the number of nodes increases. However, in throughput OLSR outperforms AODV and TORA. Keywords–AODV, MANET, OLSR, Scalability, TORA
