Although resource allocations on the Control Channel (CCH) reserved for safety-related applications have been well investigated, efficient usage of the other Service Channels (SCH) has attracted less attention. In this paper, we propose the design of an asynchronous multichannel mechanism for service management at 5.9GHz. Whereas the service phase defined in the IEEE WAVE standard requires vehicles to remain tuned on a given service channel, the proposed mechanism relies on cognitive principles to let service providers and users dynamically switch between channels and converge to a rendezvous channel where they can negotiate service support and conditions. The mechanism has been implemented on the ETSI compliant ITS simulation platform iTETRIS. We investigate the delay required to converge to such rendezvous channel and illustrate that an optimal cognitive parameter set manages to keep it within an acceptable range, and yet provides more flexibility to the channel usage.","PeriodicalId":437528,"journal":{"name":"IEEE Vehicular Networking Conference","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115331174","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}

One of the recent developments in this respect is the implementation of co-operative traffic management systems, based on the establishment of a bidirectional wireless I2V communication link for transmission of ‘legally binding’ messages into the vehicle (e.g. speed limit, incident warning, weather warning). By ensuring high accuracy, robustness, and reliability in terms of location, content and time the information transmitted via this I2V communication link has the potential to get legal character and can serve as source for Intelligent Speed Adaptation (ISA) systems.","PeriodicalId":437528,"journal":{"name":"IEEE Vehicular Networking Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133274947","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}
