Wireless Sensor Networks (WSNs) play a pivotal role in critical applications, ranging from industrial control systems to healthcare monitoring. As these networks become increasingly integrated into our daily lives, understanding their energy consumption behavior is paramount for achieving sustainability and resilience. This paper delves into the intricate relationship between energy consumption patterns in WSNs and their security implications within critical contexts. We commence by conducting a comprehensive analysis of energy consumption behavior in WSNs, considering factors such as data transmission, node mobility, and sensing activities. Through empirical studies and simulations, we identify key parameters influencing energy utilization and establish a foundation for further investigation. Building upon this understanding, we explore the security impacts associated with the energy profile of WSNs operating in critical environments. We address potential vulnerabilities arising from compromised nodes due to energy depletion, communication constraints, and malicious attacks. By examining these security challenges, we highlight the urgency of developing robust solutions to ensure the reliability and integrity of WSNs in critical applications. In response to these challenges, we propose mitigation strategies that synergistically address both energy consumption and security concerns. Our approach based on security information and event management with deep learning security use case algorithms for impact mitigation. These strategies aim to enhance the overall sustainability and security of WSNs, ensuring their continued functionality in demanding and sensitive environments. In conclusion, this paper provides a comprehensive overview of the intricate interplay between energy consumption behavior and security impacts in WSNs within critical contexts. Our findings underscore the need for holistic approaches that integrate energy-awareness and security measures to fortify the resilience of WSNs, fostering their sustainable deployment in critical applications.
