The deployment technologies are expected to spread more widely to support the long-term evolution of advanced (LTE-A) small-cells. Small-cell users indoors can take advantage of robust connections. This study focuses on maintaining the performance control systems to enable effective monitoring and administration of intelligent building operations since security services and access control have grown in importance in systems for smart buildings. It used a cooperative Radio Resource allocation approach for LTE-A systems. Within smart buildings, the goal is to improve Quality of Service (QoS) and reduce interference from users and small cells. This paper proposed an approach to effectively accommodating active mobile users within small cells. This study used an innovative approach for selecting and allocating physical resource blocks to enhance resource use. The efficacy of this technique was substantiated by research findings, which were based on simulation results. These results highlight the achievement of optimal system throughput while maintaining the QoS for users.
