A comprehensive survey on security attacks in wireless sensor network

In Wireless Sensor Network (WSN), the sensors offer fascinating real-time data about the physical environment. WSN is rapidly expanding its application areas such as environmental monitoring, industrial security, battlefield awareness, context-aware computing, and so on. One of the most difficult tasks is safeguarding real-time data due to sensor node resource limitations. This article covers a comprehensive survey of WSN security, which includes characteristics, applications, architecture, vulnerabilities, security needs, different forms of attacks on sensors, and security techniques that researchers have examined in recent years on WSN. This might provide guidance for future WSN security research.
