Protocols Security for Wireless Sensor Networks

As wireless sensor networks are growing fast so they need for effective security mechanisms as well. Sensor networks interact with sensitive data and operate in a hostile unattended environment, hence security concerns be addressed from the beginning of the network design. Due to resource and computing constraints, the biggest challenge in sensor network is to provide security in routing protocols. Many sensor network routing protocol have been proposed, but a very few have been designed with security as a goal. Asymmetric cryptographic algorithms are not suitable for sensor network providing security, as sensor nodes has limited computation, power and storage resources. On the other hand, it is not feasible to replace the batteries of thousands of sensor nodes, hence sensing, computing and communication protocols must be made as energy efficient as possible. There is currently enormous research potential in the field of wireless sensor network security. Thus, we need to be familiar with the current research in this field.
