An Energy-Efficient Cross-Layer Framework for Security in Wireless Sensor Networks

Wireless Sensor Networks represent a promising technological solution while the resources constrained and exposure to external attacks could limit their employment. The design and the implementation of an energy-efficient and effective security framework is the scope of this paper. The security framework use the information of inter-layers cross-layer optimization and inter-nodes optimization. At the same time, we present a key establishment scheme to enhance the communication security. Through analysis, our framework can resist the attacks of WSNs, and it doesn´t cost much overhead.
