Distributed spectrum sensing and channel selection in opportunistic wireless personal area networks

Abstract

This demonstrator showcases a distributed spectrum sensing and channel selection service running on a small-scale IEEE 802.15.4 opportunistic WPAN network. This service can provide spectrum awareness to the network itself or to other co-located networks. In case an interfering signal is detected the network devices are able to identify less used spectrum portions such that the network can reallocate to the best available channel. The channel occupancy can be observed in real-time via a graphical user interface.
