A Secure Scheme Based on Layer Model in Multi-Phase Sensor Networks

In some sensor networks, the pre-distribution schemes are based on deployment knowledge. As a result, the performance of such a sensor network could remarkably decline when the deployment error of nodes is large. In this letter, a secure scheme based on layer model (SS-LM) is proposed. When the deployment error is large, analysis and simulation show that the SS-LM can provide higher local connectivity and global connectivity as compared with existing schemes using deployment knowledge.
