Overview of Security Mechanisms and Attacks in Wireless Sensor Networks

WSN technology is expanding day by day. The WSN technologies which are related to network protocol have been structured for the efficiency of energy. This paper is used for examining security mechanisms which are designed for application and network layers. Wireless Sensor Networks (WSNs) are recruited in several regions in a variety of claims named as fitness, ecology, and service, for example, to rule the chief data such as the location of staff in a building for this type of example WSNs security is required. WSN which are cluster-based gives finer hold up, functionality, benefits, and output in plenty of applications, by which numerous routing protocols which are cluster based have been evolved in WSN.
