Recent Trends for Security Applications in Wireless Sensor Networks – A Technical Review

Abundant advancement in wireless sensor networks technology (WSNs) makes it possible to be used widely in monitoring the different events taking place in our daily life. All the collected data from different areas requires high attentions for the security. There are different issues and challenges in the WSN such as the energy efficiency, placement of sensor node, storage capacity and operational complexity and so on. To strengthen the security issues there are certain schemes which allow the secured communication at each step. In this paper, certain security issues and challenges are discussed for the WSN communication. In the last, different security and privacy mechanisms are discussed which used in healthcare data management.
