Abstract: The rapid growth of the Internet of Things, combined with advancements in cloud computing and next-generation wireless technologies, has created unprecedented opportunities for intelligent, interconnected systems. These systems, often referred to as wireless cloud-IoT platforms, rely on seamless connectivity to enable real-time data exchange, remote management, and advanced analytics. However, the increasing number of connected devices, diversity of communication protocols, and dynamic network conditions pose significant challenges to maintaining reliable and resilient connectivity. Resilient connectivity in this context refers to the ability of the network to maintain service continuity, recover from failures, and adapt to changing environmental and operational conditions without significant degradation in performance. This review examines the state-of-the-art approaches for achieving resilient connectivity in next-generation wireless cloud-IoT platforms, highlighting the key technological enablers such as 5G and 6G networks, low-power wide-area networks, edge and fog computing, and software-defined networking. It also provides a detailed discussion of fault-tolerant designs, adaptive and resource-aware connectivity models, and security-driven approaches that ensure continuity and reliability in heterogeneous IoT environments. By comparing existing methods and analyzing their performance metrics, this review identifies gaps in current research and outlines open challenges, including scalability, energy efficiency, and security. Furthermore, the review explores emerging directions such as artificial intelligence-driven network adaptation, digital twin integration, and autonomous connectivity management. The insights provided in this work are intended to guide researchers, engineers, and practitioners in designing next-generation wireless cloud-IoT platforms that are robust, flexible, and capable of supporting the increasing demands of smart applications. Overall, this article emphasizes the importance of resilient connectivity as a foundational requirement for the successful deployment and operation of future IoT ecosystems, offering a comprehensive overview of current solutions and potential pathways for further innovation.
