Abstract EN
In this paper, we investigate the coexistence of cognitive radio networks on TV white spaces for rural and suburban connectivity.
Although experimental models and laboratory measurements defined the maximum interference threshold for TV white space technologies for general use cases, our research found that in real wireless rural and suburban scenarios, severe interference to the broadcasting services might occur.
This is particularly relevant when the traffic load of the telecom base stations (BSs) exceeds 80% of their maximum capacity.
We propose a dynamic management algorithm for minimizing the interference, based on a centralized access control architecture for cognitive radio wireless networks.
In an experimental emulation for assessing the impact of cognitive radio interference on the broadcasting service’s QoE, our method reduced the perceived video distortion by the broadcasting users by at least 50% and 27.5% in a rural and suburban scenario, respectively, while the spectrum usage is increased by just 8%.
