Issues and Challenges in Wireless Sensor Network Security: A Survey

Wireless sensor networks (WSN), a dominant technology which rouses and changed the world upside down for the past decade. The growth of wireless sensor network (WSN) is great that it is used in almost all the fields like in telecommunication, health care, education, military and much more. The main application of these WSN is for security purpose like sensing and monitoring both domestic and foreign agents in military and identifying by sensing the earth plates movements, predicting and evicting natural disasters like earthquake, Tsunami, etc., Inclusion of the wireless sensing poses many security threats in the network. The security of the network is the main concern that is being affected or attacked more than any other layer in wireless sensor network. This paper will provide an overview of the security issues and challenges faced in the wireless network and countermeasures of those attacks. The main aim of the paper is to help readers to gain knowledge about the daily issues in the network that they face unknowingly.
