This paper presents an interference model of overlapping radio channels which allocate the same frequency band. The model is based on the INET Framework [12] of OMNeT++ [11] simulation engine and the raytracing tool Radiowave Propagation Simulator (RPS) [14]. By using our prediction model, we 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 2.4 GHz band like Wi-Fi, Bluetooth and ZigBee were launched into market which complicates a sophisticated coexistence. Therefore, we 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. Apart from other approaches, our simulation model uses a dynamic, coupled raytracing tool to compute Carrier-to-Interference (C/I) ratios directly out of the given ambient and alignment parameter set. Finally, the validity of the simulation implementation will be proven by applying a safety critical scenario in the area of rescue operations including monitoring of vital and ambient parameters.
