From previous research findings, we see that centralized solutions, VANETs, and broadcasting based approaches each show benefits and drawbacks depending on traffic density, penetration, network utilization, and other parameters; intelligent transportation systems are therefore tuned for specific settings. In order to overcome this limitation, we developed a broadcast-based solution that has been designed to carefully use only the remaining capacity of the wireless channel. Thus, it will not influence other applications using the same radio network. ATB is adaptive in two dimensions: First, the beacon interval is adapted dynamically according to the channel quality and the importance of messages in the local knowledge base, and, secondly, the protocol can dynamically make use of available infrastructure elements. Simulation experiments demonstrate that ATB performs well in a broad range of settings. It maintains a non-congested wireless channel to prevent collisions during the data exchange.","PeriodicalId":257339,"journal":{"name":"2010 IEEE Vehicular Networking Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123515044","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}

SCMs have been widely used in the area of radar target modeling, particularly for object characterization and classification. Recently, the SCM approach has been adapted to model the electromagnetic properties of vehicles embedded in a comprehensive environment for the simulation of automotive radar channels. In this paper the application of SCMs for deterministic simulations of communication channels in automotive environments is presented. The main advantage of this concept is a drastic reduction of complexity for the ray tracing simulations. Instead of using a full geometrical description of the scene, the most complex objects are replaced by an equivalent SCM and a strongly simplified surface model. The SCM of an object is determined in advance, independent from the surrounding environment. In order to achieve a precise parameterization of individual Scattering Centers (SC), the Physical Optics (PO) approximation can be applied. Unfortunately, in contrast to a parameterization based on the Geometrical Optics (GO) contribution only, this approach requires field computations for a large number of observation directions. To handle this computational challenge, a parallelization concept is presented, which is based on multi-core architectures and on the utilization of Graphics Processing Units.","PeriodicalId":257339,"journal":{"name":"2010 IEEE Vehicular Networking Conference","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128778561","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}
