Scalable Model for the Simulation of Olsr and Fast-olsr Protocols

Technological advances and rapid development of the IEEE 802.11 standard have facilitated the growth of wireless local area networks (WLAN) and mobile computing in public domains. So, the routing protocols must support a very large and fast mobility of nodes over a very large ad-hoc network. In this paper, we present a scalable simulation model and results for the Optimized Link State protocol (OLSR) and the Fast-OLSR extension. OLSR is a proactive protocol, thus it periodically sends control packets to build and update the topology. Fast-OLSR extension is designed to meet the need for fast mobility in Mobile Ad-hoc NETworks (MANETs). The aim of this article is to evaluate the performance of Fast-OLSR in a very large ad-hoc networks by applying an extensible simulation model close to a real ad-hoc network. The simulation results were obtained with an IEEE 802.11 medium access control and physical layer model. Results show that the loss rate can be minimized for the Adhoc network of nodes with fast mobility by implementing OLSR and Fast-OLSR protocols.
