Security Challenges and Solutions in IoT-Based Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) based on the Internet of Things (IoT) have transformed various industries by enabling extensive data collection and informed decision-making. However, their widespread adoption also brings significant security challenges due to their unique characteristics and limited resources. This article examines the specific security threats and vulnerabilities that affect IoT-based WSNs, focusing on attacks that compromise data confidentiality, integrity, and availability. It reviews existing security measures and their shortcomings in addressing these issues. Furthermore, the article explores advanced security solutions such as encryption methods, secure communication protocols, anomaly detection systems, and intrusion prevention mechanisms tailored specifically for IoT-based WSNs. Case studies are presented to illustrate the practical challenges and effectiveness of these security solutions in real-world applications. Finally, the article concludes by outlining future research directions and emphasizing the importance of developing robust security strategies to protect IoT-based WSNs from evolving cyber threats.
