Wireless Sensor Networks: Security, Threats, and Solutions

Abstract

Wireless sensor network (WSNs) is a rapidly growing technology that could be utilized in almost all applications like in healthcare environment, smart homes, smart building, analysis of habitat, global application, and so on. However, the development and huge deployment of WSN in different applications also raises the concerns of worst security threats, which make WSNs vulnerable to many security attacks and system failures. Usually, sensor nodes arrangement cause problems like arrangement in the deserted environment cause the WSNs to become weaker against the complicated threats or destruction, sensor nodes internal storage limitations also cause the classical arrangement of the system useless. Therefore, this papers discusses the major security goals, vulnerabilities, and threats that are associated with the layers of WSNs along with their countermeasures.
