Although AI has shown promise in enhancing security measures, its application in real-time IoT environments remains limited, with a lack of robust frameworks that effectively integrate AI-driven security solutions into IoT systems.
IoT devices operate with limited computational resources, posing a challenge for implementing advanced AI algorithms, and current research does not adequately address the balance between the computational demands of AI algorithms and the resource constraints of IoT devices. There is a need for optimized AI models specifically tailored for enhancing IoT security. Existing research often overlooks the need for AI models that are both effective and efficient, given the constrained environments in which IoT devices operate. The formulation of cost functions that accurately reflect the trade-offs between IoT vulnerability profiles and AI capabilities is underdeveloped, with current models failing to provide sufficient granularity in representing the relative importance of various factors, leading to suboptimal resource allocation and security outcomes.
There is limited research on the application of AI for predictive maintenance and decision-making in IoT systems, with most existing studies focusing on individual aspects rather than an integrated approach that combines AI-driven security enhancements with predictive maintenance strategies.
To address these gaps, this research aims to develop comprehensive security mechanisms that consider the unique vulnerabilities and constraints of IoT devices, create robust frameworks for the real-time integration of AI-driven security solutions in IoT systems, design and implement AI models optimized for the resource constraints of IoT devices, ensuring both efficiency and effectiveness, formulate detailed cost functions that accurately capture the trade-offs between vulnerability profiles and AI capabilities, explore the use of AI for predictive maintenance and decision-making within IoT systems, providing an integrated approach to security and performance optimization, and conduct context-specific research to tailor solutions for various IoT environments, enhancing the practical applicability of the findings.
