Lysis chatbot: A virtual assistant for IoT platforms

Pages 81-91
Raimondo Cossu, Roberto Girau, Luigi Atzori

The configuration and management of devices and applications in Internet of Things (IoT) platforms
may be very complicated for a user, which may limit the usage of relevant functionalities and which
does not allow its full potential to be exploited. To address this issue, in this paper we present a new
chatbot which is intended to assist the user in interacting with an IoT platform and allow them to use
and exploit its full potential. The requirements for a user-centric design of the chatbot are first analyzed,
then a proper solution is designed which exploits a serverless approach and makes extensive use of
Artificial Intelligence (AI) tools. The developed chatbot is integrated with Telegram to message
between the user and the Lysis IoT platform. The performance of the developed chatbot is analyzed to
assess its effectiveness when accessing the platform, set the main devices' parameters and request data
of interest.

Resource tokenization for crowdfunding of wireless networks

Pages 93-100
Volkan Sevindik
This paper presents a novel blockchain-based spectrum tokenization method used to crowdsource
wireless network deployment projects. Crowdsourcing is a method of financing certain projects and
ideas through the funds collected by individuals or businesses in an open marketplace. The method
presented in this paper finances the wireless network deployment projects belonging to service
providers or governments. The method tokenizes proposed novel wireless resource units, and sells these
units to investors. A new Value Unit Per User (VUPU) resource unit is introduced with a new pricing
scheme depending on a load of a base station. A novel Proof of Data Load (PoDLO) consensus
algorithm is proposed which is used to verify data and traffic load of a base station. Device Diversity
Factor (DDF) and Subscriber Unique Permanent Identifier (SUPI) Factor (SUF) are proposed new ways
to determine the value of a base station and a network cluster.
