Security and Privacy in WSN

The network of sensors that covers a region and provides information about it is a Wireless Sensor Network in its simplest form. It uses wireless links to communicate the data gathered from monitored field and environment [1]. Network of devices that can communicate gathered information from monitoring field through wireless links and process it is known as Wireless Sensor Network. Communication through wireless medium is booming in today's era. As wireless networks are very useful in remote places, it also has some serious security issues that can be harmful for entire network system. Hence security of wireless networks and so the information that it relays attracts more attention in deploying the complete infrastructure. Some of the security protocols defined for security purpose have most importance in designing security model for sensor networks.
