A New Dynamic Co-Channel Interference Model for Simulation of Heterogeneous Wireless Networks

This paper presents an interference model of overlapping radio channels which allocate the same frequency band. The model is based on the INET Framework of OMNeT++ simulation engine and the raytracing tool Radiowave Propagation Simulator (RPS). By using the authors' prediction model, they present a proposal for an easier integration of adaptive bit rate adjustment for wireless networks in OMNeT++. Since a few years, an increasing amount of technologies that use the public domain 2.4GHz band like Wi-Fi, Bluetooth and ZigBee were launched into market which complicates a sophisticated coexistence. Therefore, they want to analyze a channel model that regards not only various Physical Layer specific circumstances but also the alignment of the different networks operating in their particular scenarios.
