Research for Reputation Models in VANET
As a typical open distributed system,the Vehicular Ad hoc NETworks(VANET) are composed ephemerally due to their high mobility.Vehicle nodes in the VANET are facing with various malicious nodes and hard to choose trustworthy collaborative nodes in applications.To solve these problems,we design VANET application specified reputation models(VASRep) to qualifiedly evaluate the reputation of the nodes.Through merging various types of information sources in VANET,VASRep can express the node′s trustworthiness more accurately.According to the authority units′ recommendation,VASRep is more suitable to VANET environments.Finally,the analysis and evaluation show that our model outperforms the existing solutions in terms of performance and resisting the attack of malicious nodes.
