XLSEC - A Distributed Cross-Layer Framework for Security in Wireless Sensor Networks

In this work, we addressed the need for cross-layer optimizations in wireless security. We proposed a cross-layer security framework with interactions across layer boundaries (vertical optimization) as well as node boundaries (horizontal optimization). We modeled different attacks at the network layer and application layer to illustrate the detection performance of the XLSEC framework. Preliminary simulation results indicate high detection gains using such cross-layer adaptations.
