Frequency-hopping based Secure Schemes in Sensornets

Frequency-hopping is a kind of secure solution in wireless communication field. We propose two novel mechanisms based on differential frequency-hopping to prevent those attacks like jamming, eavesdropping, tampering, etc. in wireless sensor networks (WSN). We also present the deployment scheme of our secure solutions. The analysis in this paper indicates that these two solutions have a number of good properties like energy efficiency, asynchrony, robustness and effectiveness to prevent the majority attacks in WSN
