Energy Efficiency and Security for IoT Scenarios via WSN, RFID and NFC : Invited Paper

The given work is aimed to investigation of the energy efficiency issues for IoT devices, based on combined mobile, wireless, sensor and contactless solutions. Furthermore, the security issues are discussed. The combined energy-efficient solutions are namely the hierarchical organized infrastructure WSNs and self-organized ad-hoc WSNs, which are widely interoperable with the 4G/5G base stations and micro-cells, the backboned Wi-Fi access points as well as with inexpensive and energy-efficient RFID/ NFC tags. The given scenarios provide multilateral security for IoT devices under use of not only of PKI, hash computing and digital signatures, but also under use of Blockchain technology. Resource-intensive blockchain-based applications are by far compensated via a row of unquestionable advantages, provided by “blockchained IoT”!
