Smart Building (SB) is an Internet of Things (IoT) application that aims to manage buildings without human intervention. SB interconnects almost all IoT-enabled devices in the home, such as lights, car parking, temperature sensors, AC, and so on. Another important component of SB is that can provide real-time information. On the other hand, Software Defined Networking (SDN) is a networking technology that can easily transfer and modify information from the data layer to the control layer through the SDN protocol. Currently, intelligent cities, offices, and large organizations are being developed based on SDN and IoT. Among them, many researchers have completed their work on this technology and they have faced various problems. Based on the above discussion, we propose an SB secure architecture model where multiple controllers are used to protecting the building from problems like a single point of failure. Moreover, the southbound protocol is used between the data layer and the controller layer to protect the security and privacy of the building, and through the northbound protocol, customer data is stored in cloud storage. Finally, the author evaluates the performance of the proposed model with various network metrics (Throughput, Round Trip Time) and CPU, Memory and Bandwidth Utilization rate.
