And there are also other existing mobile communications available for automotive. But in WAVE (DSRSC) activities in world wide i.e. C2C-CC (Car to Car Communication Consortium) ITS Japan, IntelliDrive1), there is no discussion for high speed access which communicates with Internet world yet. This paper provides practical wireless communication system guide line especially for automotive network applications among potential wireless communication systems including existing network technology such as 3G or UMTS (Universal Mobile Telecommunications System) including next broadband access WiMAX. Authors provide more practical method for wireless communication architecture design. In previous paper2) for 5.9GHz DSRC cell design for next DSRC, it was introduced cell design concept using mobile communication cell design method into vehicle wireless communication design and provides new DSRC architecture design but only 5.9GHz frequency band. In this paper, authors expand potential wireless communication technologies from DRSC to 3G and WiMAX. And authors provide practical vehicle wireless communication systems for next new DSRC applications.","PeriodicalId":117027,"journal":{"name":"2010 Wireless Telecommunications Symposium (WTS)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131250978","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}

We investigate networks where all nodes have a single-radio antenna, the MAC layer protocol is synchronized OFDM, and each channel uses TDMA. In such networks, data collisions can be avoided by reserving data time-slots. Data loss can also occur when a receiving node changes its assigned channel, hence it does not completely receive the data which is on the link. We call this type of loss data corruption. Our simulations show that if there are several available time slots to reserve, a proper channel and time-slot selection algorithm is required to prevent data corruption. Consequently, it is better that a node changes channels as infrequently as possible and any necessary change should take place at an appropriate time. The same is true about switching between receiving and sending modes, i.e. switching modes also leads to data loss, so it should be avoided whenever possible. In this study we propose a new algorithm to allocate channels and time-slots so as to decrease data loss.","PeriodicalId":117027,"journal":{"name":"2010 Wireless Telecommunications Symposium (WTS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116851386","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}

This preemption capability is one of the most required features for the operation of tactical networks. And, it can be achieved by sacrificing QoSs for traditional class-based non mission-critical flows along the path for the delivery of those mission-critical data. Multilevel precedence and preemption (MLPP) has been developed for circuit-switched military networks. Since the paths to deliver data in circuit-switched networks are explicitly established, the implementation of MLPP is very simple,. However, since paths to deliver data are implicit and varying according to the changes of topologies in packet-switched and mobile ad-hoc networks, it is very difficult to implement the precedence capability. In this paper, we propose a preemptive control method to guarantee the delivery of mission-critical data in wireless mesh network (WMN)-based mobile tactical networks. To provide the preemption capability, we also propose a method to establish an explicit path in WMN environment. With the explicitly established path, cross layer-based queue management scheme at each node along the path is also proposed. The performances of the proposed method are evaluated through simulations, and the results show that the proposed method is very suitable to support preemptive mission-critical data delivery.","PeriodicalId":117027,"journal":{"name":"2010 Wireless Telecommunications Symposium (WTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128210508","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}
