A New Dynamic Co-Channel Interference Model for Simulation of Heterogeneous Wireless Networks
Source: Technische Universität Dortmund
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.
