An association of private and public companies or two more organizations have collaborated for greater
 common achievement or to enable sharing resource pools due to the economic aspect. However, the most common
 traditional access control mechanism based on a centralized system is suffering from data bulkage and solitary-point
 failure. Recently, many researchers are investigating the prospects of tackling the issue of conventional access control
 with the help of modern technology like Blockchain. But such solution overlooks the scalability challenges and
 considers the importance of flexibility/dynamic mechanism. To fill these gaps, we design a decentralized reputation
 and trust-based access control technique. We name our proposed system as IoT Consortium reputation and trust-based
 Access Control Model (IoT-RTS). Not only blockchain- is used in our proposed solution to improve performance but
 also both conventional and blockchain database exhibits advances features. We design a voice authentication system to
 improve the scores of reputations and trust in the Internet of Thing (IoT) network. Our proposed model achieves
 secured, dynamic and smart access control. The secure, smart IoT-RTS meets the effective solution for business and
 enterprise purposes and is applicable for many applications leveraging IoT.
