Energy Efficient Link Layer Security Protocol in WSN

Abstract

An ad-hoc mobile Wireless Sensor Network is a collection of mobile sensor nodes that are dynamically and randomly located in such a manner that the interconnections between nodes are capable of changing on a continual basis. Although the primary goal of such an ad-hoc network is correct and efficient route establishment between source and destination so that messages may be delivered in a timely manner but military tactical and other security-sensitive operations are still the main applications of ad hoc networks. One main challenge in design of these networks is their vulnerability to security attacks. In this project, threats an ad hoc network faces and the security goals to be achieved have been reviewed. In particular, it takes advantage of multiple routes between nodes — to defend routing against denial of service attacks and cryptographic schemes to prevent from malicious attacks by intruders and to build a highly secure and highly available key management service, which forms the core of our security framework.
