异构无线网络中基于QoS业务感知的信任管理模型

针对异构无线网络中的信任评估问题,提出了一种基于用户QoS感知的信任管理模型。该模型基于异构网络中业务交互及由此产生的用户QoS感知,刻画节点间的信任关系与信任度;并针对QoS感知的主观性和网络欺骗行为,给出了相应的信任策略。理论分析和仿真结果表明:该模型不仅能够有效地完成异构网络环境下的节点信任评估,并能抵御虚假欺骗、振荡服务等恶意行为。

A Trust Management Model Based on QoS Service Experience for Heterogeneous Wireless Network

For the trust evaluation problem in heterogeneous wireless network,a trust management model based on user experience of QoS is proposed.The model uses the heterogeneous network service interaction and the resulting user experience of QoS to describe trust relationship among nodes.For the problems about subjectivity in QoS experience and network cheating,the corresponding trust strategy is given.Theoretical analysis and simulation results show that the model can effectively achieve the node trust evaluation in the heterogeneous wireless networks,and can resist the network cheating,on-off service and other malicious behaviors.
