However, an unacceptably high transmit power is required. Multi-hop technique can solve this problem. To reduce the transmit power, while increasing the transmission data rate, we have proposed a wireless multi-hop virtual cellular network (VCN). In this paper, we introduce the multi-hop VCN for high speed wireless network and discuss the channel capacity performance of the multi-hop VCN.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115166083","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}

There are two types of pseudolite system. The one is synchronous system and the other is asynchronous system. For the asynchronous system, user requires RF link to be provided augmentation data for timing and reference station for monitoring timing offsets of pseudolites. For the synchronous system, User does not require RF link for augmentation data but it still need reference station for monitoring timing offsets of pseudolites and the reference station need RF link with pseudolites for providing timing offset information for synchronizing slave pseudolites with master pseudolite. A synchronous pseudolite system with single clock which can cut down cost for the pseudolite system is presented in this paper. Also we will present configuration, operation concept, and preliminary simulation result for it.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127197392","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}

As the architecture of the sensor networks becomes to rely on the applications more heavily, we believe that it is considerably important to come up with USN middleware which provides functions common to different types of USN applications and services. In this paper, we analyze the USN middleware architecture and three USN service use cases described in the ITU-T F.744 recommendation, and suggest the fundamental functions and interfaces for the ITU-T USN middleware components.1","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129743181","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}

IPTV in the home is starting to dominate the market and is set to replace the way we watch our media content from watching it when broadcast to watching it on demand. Existing home gateway solutions or access points can allocate bandwidth to users depending on traffic priority or on a first come first served basis. This however might not be an optimal choice of allocation since it does not take into account user privileges and user perceived quality. This paper proposes a Cognitive Resource Manager, which takes into account these factors for managing the resources in the home. The paper suggests methods for learning user preferences by employing simple machine learning techniques and defines a user satisfaction utility, then optimizes it, choosing the optimal configuration for resource allocation. The paper also proposes a more lightweight heuristic approach which approximates the optimal configuration for resource allocation at a lower computational cost. This method of resource allocation compares favorably to a number of alternative strategies with respect to fairness.","PeriodicalId":149198,"journal":{"name":"2010 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131259378","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}
