This paper proposes the design and implementation of a 5G IoT based Smart Residential Building using the most recent version of CISCO Packet Tracer (a simulation software). Different smart IoE devices were used for automation which allow distant monitoring and controlling. Since these buildings are vulnerable to cyber-attacks and security threats, this paper also analyzes the proposed security framework and how such an implementation on using various sensors and actuators enables us to enhance the security and safety. In addition to this, we also outline the measures to be taken by the government and building owners to strengthen the security. The simulation results show that integrating 5G and IoT is a promising and cost-effective if it gets implemented practically in the real world. Keywords: Smart Residential Buildings, 5G, IoT, Cisco Packet Tracer Simulator I. INTRODUCTION Internet of Things (IoT) and 5G are like “two halves of a whole”. The main goal of integrating 5G and IoT lies behind its ability to drive advancements and achieve a sustainable future. The powerful integration of IoT and 5G has spurred a more practical implementation of technologies such as that of Smart Residential Buildings. The motivation of this paper is to integrate the IoT and 5G in home automation using a simulator Cisco Packet Tracer version 8.1 and to incorporate several security and safety features into our implementation which in turn makes it a “Smart Residential Building”. While rest of the paper is organized as follows: Section II presents the review of the related study, followed by Section III methodology while Section IV the implementation. Further, Section V is the analysis of security and safety features. Finally, the conclusion
