Abstract: The rapid proliferation of Internet of Things (IoT) devices has significantly transformed the digital landscape, generating massive volumes of heterogeneous data and demanding robust computational and networking infrastructures. Cloud computing has emerged as a cornerstone technology for managing this data, offering scalable storage, computation, and advanced analytics. Simultaneously, wireless networks provide the essential connectivity that enables IoT devices to communicate efficiently, both locally and across geographically distributed infrastructures. The convergence of IoT, cloud computing, and wireless networks represents a multi-layer system, where each layer from perception and sensing to network communication and cloud-based processing plays a critical role in ensuring system efficiency, reliability, and scalability. This review comprehensively examines the current state of multi-layer system architectures, focusing on how IoT devices, wireless communication technologies, and cloud services integrate to form cohesive, high-performance ecosystems. Key performance metrics, including throughput, latency, energy efficiency, and quality of service (QoS), are analyzed to assess the effectiveness of different convergence strategies. Furthermore, the review addresses end-to-end security and privacy considerations, highlighting layer-specific challenges such as device authentication, secure data transmission, cloud data integrity, and privacy-preserving mechanisms. Case studies of implemented converged systems are discussed to illustrate practical applications and identify best practices. Emerging trends in edge and fog computing, artificial intelligence (AI) for resource optimization, next-generation wireless networks (5G and 6G), and digital twin integration are examined to highlight future directions for multi-layer IoT-cloud convergence. The review identifies existing research gaps and presents recommendations for overcoming challenges in interoperability, standardization, energy efficiency, and intelligent orchestration. By providing a comprehensive, multi-layer perspective, this work serves as a valuable reference for system architects, researchers, and engineers aiming to design scalable, secure, and efficient IoT-cloud ecosystems.
