New Long-Range radio technologies have recently emerged in the IoT landscape. These technologies work in the Sub-GHz bands, allowing low-power communications over long distances. They are typically based on star-topology networks, where nodes send the data directly to a base station connected to the Internet. One of such technologies is LoRa. Enabled LoRa-based multihop communications would open up...
The performances of three different asynchronous radio duty cycling protocols available in the Contiki lightweight operating system have been compared experimentally in view of their adoption in medium sized wireless sensor networks integrated in the Internet of Things. This study unveils some of the subtleties of those protocols, allowing an improved tuning of their parameters, as well as the identification...
New Long-Range radio technologies have recently appeared in the IoT landscape. Combining the existing communication protocols with these novel radio technologies could increase the potential opportunities and the diversity of use cases for Wireless Sensor Networks. In this paper, an implementation of a LoRa based sensor platform that uses the Contiki OS is proposed, in order to enable standardized...
