This kind of communication uses the IEEE 802.11 standard for physical and MAC layer. In order to solve the hidden problem, the IEEE 802.11 uses the RTS/CTS mechanism. Because of the highest mobility in VANET, the RTS/CTS may introduce performance degradation. In this paper, we clarify these effects by studying the influence of this mechanism on the global performance (delay, loss packet...) in terms of bandwidth, packet size...

The performance of the bandpass filter structure has been analyzed using a method of moments (MoM) based software package, Microwave Office 2009, from Advanced Wave Research Inc.

The complex shaped-slot was generated randomly by applying the cellular automata technique. Analysis of simulated results dealing with the impedance matching, surface currents, gain and radiation patterns, shows three different behaviors: improvement of the impedance matching, rejection of one band, and rejection of two bands, depending on the shape and position of the slot. It is found that both the impedance matching and the gain of the UWB antenna can be enhanced for some particular shaped slots.","PeriodicalId":361750,"journal":{"name":"2013 13th Mediterranean Microwave Symposium (MMS)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115539838","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}
