Abstract

Effectively managing network resources in the complex and ever-evolving domain of Internet of Things (IoT) ecosystems presents a formidable challenge. Conventional resource allocation methods often engaged with adapting to the dynamic nature of IoT environments, resulting in suboptimal performance and delayed responsiveness. The advent of state-of-the-art network technologies, notably intelligent reflecting surfaces (IRSs), further amplifies complexity, particularly in optimizing IRS configurations within dynamic networks. To address these complexities, this article introduces DTRiD, a fusion framework uniting digital twins (DTs), IRSs, and deep deterministic policy gradient (DDPG) to tackle these challenges. DTRiD offers a distinctive integration of DTs, IRS functionalities, and DDPGs, all aimed at augmenting communication and resource allocation within the IoT. By utilizing real-world data from wireless networks, DTRiD compiles a diverse data set capturing various network conditions. Extensive simulations demonstrate the framework's superiority over conventional methodologies across key metrics, including accuracy, convergence, delay reduction, and energy efficiency in multiple dimensions. These results show the potential of DTRiD in restructuring the landscape of IoT communication by optimizing resource allocation dynamically, enabling it to handle complex scenarios and adapt to diverse environmental changes.
