Towards Survivable Sensor Networks Using Self-Regenerative Rejuvenation and Reconfiguration

The previous works in sensor networks security have focused on the aspect of confidentiality, authentication and integrity based on cryptographic primitives. There has been no prior work to assess the survivability in systematic way. In this paper, we propose a framework for enhancing the survivability of sensor networks using self-regenerative software rejuvenation and reconfiguration. We utilize self- regenerative capabilities for detecting misbehaving in node level and apply software rejuvenation and reconfiguration methodology or both in order to extend the availability of sensor networks. The security analysis shows the feasibility of our approach.
