On the Accuracy of Interference Models in Wireless Communications
2016 (English)Conference paper (Refereed)
We develop a new framework for measuring andcomparing the accuracy of any wireless interference models usedin the analysis and design of wireless networks. Our approach isbased on a new index that assesses the ability of the interferencemodel to correctly predict harmful interference events, i.e., linkoutages. We use this new index to quantify the accuracy ofvarious interference models used in the literature, under variousscenarios such as Rayleigh fading wireless channels, directionalantennas, and blockage (impenetrable obstacles) in the network.Our analysis reveals that in highly directional antenna settingswith obstructions, even simple interference models (e.g., theclassical protocol model) are accurate, while with omnidirectionalantennas, more sophisticated and complex interference models(e.g., the classical physical model) are necessary. Our newapproach makes it possible to adopt the appropriate interferencemodel of adequate accuracy and simplicity in different settings.
