A comparative study of simulation based performance evaluation of routing protocol for ad-hoc networks

Abstract

This study introduces comparison of two simulation-based performance evaluation papers, the first paper called “APerformance Comparison of Multi-HopWirelessAdHoc NetworkRouting Protocols” and the second one called “Simulation-based Performance Evaluation of Routing Protocols for Mobile Ad Hoc Networks”. This paper criticizes the choices selection for each simulation. These two papers present a performance evaluation of four typical routing protocols of ad-hoc networks which are DSDV, TORA,DSR, andAODV using the simulation technique. As the performance of an ad-hoc network protocol can vary significantly with differentmobility model the first and the second paper chooses a different mobility model “Waypoint” and “Gauss-Markov” model, respectively. This leads to a different behavior of each model results. The first paper found out to be more systematic, realistic, and its performance evaluation has a better level of details including theMAC and link layer details in the simulation rather than the second paper which is more superior mainly in choosing “Gauss-Markov” mobility model. Furthermore, it found out the first paper’s “end-to-end delay” metric is more proper choice over the second paper’s “path optimality”metric since it depends on the algorithm more than the load.
