IoT boosts industry productivity and efficiency by judiciously combining sensors and actuators with computing platforms via different means of communications technologies to get data gathering and analytics. IoT system design essentially requires considering data transmission reliability. This paper presents a review of the commonly used communication means in current and future Internet of Things (IoT) applications. The Paper will also cover technologies, data and communication protocols and their common application domains. Wireless technologies are growing in a way to provide wide efficient challenging IoT-based applications. actively all around the world. 5G and 6G wireless technologies with satellite integration wireless open a new era of IoT. A brief overview of reliability metrics; resource allocation and latency management which are crucial for maintaining a reliable IoT application, is also given. The main required procedure required for designing an IoT system is provided. This paper paves the way for establishing a standard way to design an efficient IoT system for a certain application. All these issues will provide light on a few crucial open research issues for a reliable IoT that requires additional research, including those relating to machine learning methods, 6G communications, blockchain-based security, SDN and Computing and quantum communication technologies.
