However, VANET is prone to different attacks resulting in the dissemination of compromised/false information among network nodes. One way to manage a secure and trusted network is to introduce trust among the vehicular nodes. To this end, various Trust Models (TMs) are developed for VANET and can be broadly categorized into three classes, Entity-oriented Trust Models (ETM), Data oriented Trust Models (DTM) and Hybrid Trust Models (HTM). These TMs evaluate trust based on the received information (data), the vehicle (entity) or both through different mechanisms. In this paper, we present a comparative study of the three TMs. Furthermore, we evaluate these TMs against the different trust, security and quality-of-service related benchmarks. Simulation results revealed that all these TMs have deficiencies in terms of end-to-end delays, event detection probabilities and false positive rates. This study can be used as a guideline for researchers to design new efficient and effective TMs for VANET.","PeriodicalId":432101,"journal":{"name":"2019 Wireless Days (WD)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125486822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim is to find the optimal system-wide schedule of a multi-cell system to understand how much a fully coordinated scheduling could improve performance. It is a highly non-convex integer problem. We propose a method to upper bound this problem by a signo-mial programming problem that can be solved. The solution to the signomial problem can be used to derive a feasible solution to the original global scheduling problem. We show numerically that the gap between the upper bound and that feasible solution is very small. We then provide results both for homogeneous and heterogeneous networks. In the homogeneous case, we show that the coordinated scheduling significantly outperforms a simple benchmark that uses a local scheduling based on equal power. However, the centralized scheduler is very complex and it requires all the channel state information in the system. Therefore, we use the feasible solutions to the system-wide problem to derive a practical scheme based on a well-parameterized soft frequency reuse and a simple local scheduler. We show that the coordinated scheduling performs only 20% better than this practical scheme. The method we study can also be applied to obtain an upper bound for the case of heterogeneous networks. We compare the solution obtained by fully coordinating the scheduling of all the base stations with practical schemes inspired by the one obtained for the homogeneous case and show that the difference between the upper bound and the performance of the best of these schemes is 21%, which again questions the need for coordination.","PeriodicalId":432101,"journal":{"name":"2019 Wireless Days (WD)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131711718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
