Secure Multiple Deployment in Wireless Sensor Networks

As a fundamental requirement for providing security functionality in sensor networks, key management plays a central role in authentication and encryption. In this paper, we propose the adaptive key selection (AKS) scheme and the adaptive key selection algorithm for secure multiple deployment in sensor networks that target at providing high connectivity between different deployment sets of sensor nodes. Our simulation shows that the AKS scheme can greatly improve the connectivity of sensor nodes while maintaining the security of an existing multiple deployment scheme at the same time.
