A review on existing security frameworks with efficient energy preservation techniques in Wireless Sensor Networks

Wireless Sensor Network (WSN) is an emerging technology that shows great promise for various futuristic applications like military, nuclear power plant, health care etc., where security is a critical issue. However WSN possess various constraints like low computation capability, limited memory, reduced battery life, lack of infrastructure which imposes security as an additional challenging task. In this paper a detailed investigation on the security related issues and challenges in WSN are made. Also an overview on various security frameworks with efficient energy preservation techniques is given.
