Abstract
This paper presents a demonstrator of a multi-hop 6LoWPAN provided with frequency-agility extensions. A reference architecture is presented along with the basic components introduced to build a distributed spectrum sensing and interference resolution service in a multi-hop environment. Moreover, a frequency-agility management plane is proposed for the 6LoWPAN communication stack. The proposed solution is implemented in a small-scale network adopting TinyOS and an open-source implementation of 6LoWPAN protocol stack. The resulting demonstrator proves the capability of the proposed system to characterize the spectrum occupancy state in a multi-hop environment. In addition, it shows the ability of the network to reallocate to the best available channel in case a critical level of interference is detected on the current operating channel.
