Impact of physical propagation environment on ad-hoc network routing protocols. (22nd July 2009) - Pradhan, Nuraj
In this paper, we analyse the impact of physical propagation model on the performance of ad-hoc network routing protocols. The impact of different propagation environments on a typical routing protocol such as Optimised Link-State Routing (OLSR) is presented through simulations. A log-distance path loss model, log-normal shadowing model and rayleigh fading model is used to model the dynamic physical channel for two different environments: open _environment characterised by open area, and city _environment characterised by urban environment. We will show that network throughput degrades; average delay and routing packet overhead significantly increase in a higher attenuating environment such as the city_environment.
