基于链接的无线传感器网络簇中可信模型

通过引入社会网络中链接的概念,提出1种无线传感器网络簇中可信模型,以更有效地检测非正常节点。模型把对节点的信任分成持久信任和即时信任,在即时信任和持久信任的基础上计算每个节点的信誉,利用信誉检测非正常节点。通过实验分析了阀值的取值并将本研究模型与其他模型进行比较。实验结果表明,在检测非正常节点方面,基于链接的簇中可信模型比GTMS(group-based trust management scheme)和RFSN(reputation-based framework for sensor network)更为优秀。

Link-based trusted cluster model for wireless sensor network

The trusted cluster model for wireless sensor network was proposed to detect the abnormal nodes effectively by using link of social network. Trust was divided into permanent trust and temporary trust. Each nodes reputation was calculated to detect the abnormal nodes combining permanent trust with temporary trust. In the experiments, the threshold value was discussed and the proposed model was compared with other models. The results showed the link-based trusted cluster model for wireless sensor network was better than GTMS(group-based trust management scheme)and RFSN(reputation-based framework for sensor network)in detecting the abnormal nodes.
