SECURE AND ENERGY-EFFICIENT COMMUNICATION FRAMEWORK FOR IOT NETWORKS

Abstract

The rapid expansion of Internet of Things (IoT) networks has enabled a wide range of applications, including smart cities, healthcare monitoring, industrial automation, and intelligent transportation systems. However, IoT devices are typically resource-constrained in terms of power, computation, and memory, making them vulnerable to security threats while operating under strict energy limitations. Conventional security mechanisms often introduce significant communication and computational overhead, leading to increased energy consumption and reduced network lifetime. This paper presents a secure and energy-efficient communication framework for IoT networks that integrates lightweight cryptographic techniques with energy-aware communication strategies. The proposed framework aims to ensure data confidentiality, integrity, and authentication while minimizing energy expenditure. Analytical evaluation and simulation results demonstrate that the proposed approach enhances security and prolongs network lifetime compared to conventional IoT communication schemes
