Blockchain-Aided Distributed Device-Free Wireless Sensing with IoT Devices in Edge Network

Recently, the popularity of Internet of Things (IoT) devices has brought massive amounts of sensing data to edge networks. How to use distributed sensing data to train artificial intelligence (AI) models for ubiquitous intelligent wireless sensing in IoT, while considering privacy is an open problem. In this paper, we propose an edge intelligence (EI) and blockchain powered device-free wireless sensing framework to supply IoT applications in edge networks. We design a cross-domain wireless sensing scheme for human-computer interaction by adopting adversarial transfer learning in this framework and verify the effectiveness of the method.
