A Green and Secure IoT Framework for Intelligent Buildings based on Fog Computing

Abstract

The Internet of Things (IoT) provides an opportunity to connect plethora devices and make them capable of serving the cities better in a collaborative manner. However, energy-efficiency and security problems are the two hugest chanllenges that severely hinder the development of IoT-based smart cities. In this article, we attempt to provide a green and secure IoT framework for Intelligent Buildings which are basic elements in smart cities. Specifically, a smart agent node is installed for each Intelligent Building to make it an autonomous region. The IoT data are divided into different categories according to their application domain, priorities, meanings and potential value. The resources of IoT are precisely controlled and managed to satisfy the data users under the strictly limitation. Simulation results illustrate the effectiveness of our framework in terms of quality of service (QoS). We believe that this is a meaningful and initiatory explonation to make the smart cities more practical. Finally, some research challenges are highlighted.
