Security issues, challenges and solutions for Wireless Sensor Networks (WSN): A review

Wireless sensor networks have influenced our daily life in recent years by providing different services such as remote environmental monitoring, infrastructure health monitoring, tracking the target, home and office automation and safety, public security, event-detection, identification of event boundaries, medicine, transport, etc. Since sensor nodes are generally used in hostile and unattended conditions, they are more likely to undergo various types of attacks. The issue of WSN security attacks is not only because they have small, powerful hardware platforms that integrate data sensing & processing along with wireless connections but also because of their vast areas of applications. In this document, we tried to examine all the known security issues and challenges in wireless sensor networks and provided the defense and counteraction research solution to the security-threatening attacks.
