A Secure Scheme for Heterogeneous Sensor Networks
Sujun Li, Weiping Wang, Zhou Boqing, Jianxin Wang, Yun Cheng, Jie Wu · IEEE Wireless Communications Letters · 2017
Heterogeneous sensor networks (HSNs) consist of a small number of powerful high-end sensors (H-sensors) and a large number of low-end sensors (L-sensors). HSNs are vulnerable to H-sensors replication attack. In this letter, a scheme against the attack is proposed. The analysis and simulation results indicate that the scheme can improve networks' resilience against H-sensors replication attack as compared with existing related schemes.
