A Self-Adaptive Blockchain Framework to Balance Performance, Security, and Energy Consumption in IoT applications

摘要

The Internet of Things (IoT) is “the network of physical objects, devices, vehicles, buildings and other items embedded with electronics, software, sensors, and network connectivity which allows them to gather and exchange data” [1]. The main feature of IoT is its notable impact on various aspects of the daily life of potential users. Some examples of the possible applications where IoT will play a leading role in the next years include Smart Buildings, healthcare and enhanced learning [2]. There are several challenges that IoT poses to organizations and developers such as security, big-data, heterogeneity, variety and variability, real-time deployment and logging, integration, and many others. The privacy risks of IoT are exacerbated by a lack of fundamental security safeguards in many of the first generation IoT products on the market, for instance, in video surveillance and the cameras which can be considered as “things” [3], [4].
