Wireless Sensor Network and Its Security Threats – A Study
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 12
Abstract
A data network is a digital telecommunications network that allows nodes to share resources. Two types of networks are available, wired and wireless networks. Wireless networks become popular because of its wireless setup and its abundant applications in home, business and telecommunications networking. With the invent of sensor which react and notice some type of input from the physical or environmental conditions, such as pressure, temperature, beam, Wireless sensor network developed. The WSN are stretchy, simple to employ and straight forward. They are growing because of low cost and efficient. Wireless Sensor Networks consist of many sensor nodes that are distributed in a field and have physical capabilities to measure or sense things in the real world, do some computations, communicate with each other and deliver result to base station. With the rising expertise, the things on security are also advancing day by day. Though the network completely secured during the time of designing, intruders and attackers always find their way to get inside it and accomplish attacks. This paper presents a noteworthy analysis on the security threats of wireless sensor network. Threats are of two types active and passive attacks. Passive attacks are just listening the communication lines, whereas active attacks are modifying the data in communication lines. Different threats belonging to active and passive threats are studied in detail.
