Major objective of this lecture is to explain Security in Wireless Sensor Networks. Security is critical for such networks deployed in hostile environments. Most sensor networks actively monitor their surroundings, and it is often easy to deduce information other than the data monitored. Here briefly describe why Security Complicated in WSN, Guiding Principles for Securing WSN, Evaluation Metrics to Security Scheme and Issues with High-Level Security Mechanisms.
