SDIoBoT: A Software-Defined Internet of Blockchains of Things Model
Navid Rajabi, Jihad Qaddour · The Internet of Things · 2019
Internet of things (IoT) has been attracting the technology world as an integral part for implementation of smart buildings, smart cities and actually, smart world (which is destination of the current trend with the aim of connecting everything to everything). However, some major problems like security issues, lack of sufficient processing power, etc. will prevent researchers and major tech companies to reach a consensus to finalize a highly-secure, efficient architecture for smart cities. In this paper, we’ve proposed a new model to tackle well-known IoT implementation challenges by using software-defined networking (SDN) architecture as an integral part for acting as the brain of the model and one of the significant components of the future 5G telecommunication networks. In addition to that, we’ve taken advantages of the Blockchain technology to enhance the security of IoT networks which will be an integral part of the future smart world paradigm. The security of the model is provided by leveraging Elliptic Curve Digital Signature Algorithm (ECDSA) that is being used in Bitcoin for integrity.
