However, the performance of such type of systems can be degraded, due to the factor of non-accurate sensing of the spectrum. The growing concern regarding environmental issues and emerging green communication paradigm prospective, the cognitive radio network (CRN) can also be considered from the energy perspective. The quest for efficient system's is primarily because of cost effectiveness, longer battery time and the most important environmental issues. This paper considers the relation between the control channel power and the data channel power of the cognitive user. Energy should be consumed effectively for cost-effective systems. In this paper, we have proposed distance equation with reference to a CRN constituting of a cognitive base station (CBS), primary transceiver pair and a cognitive user (CU) under the collision probability constraint. We analyzed these distances with respect to control and data channel powers. Computer simulation are presented to evaluate the plausible region for transmission of a cognitive user for a targeted data rate using Lame Curve.","PeriodicalId":299228,"journal":{"name":"2014 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125838992","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}

The protocol can be considered for proximate space links for the space internet mission which expects to be included in Korean lunar project. However, considering the scenario of the space internet mission and the requirement of its communication payload, the proximity-1 protocol needs to be updated under the scenario of the space internet mission with high data rate and simplified under the requirement of its communication payload in terms of size, weight and power. In this paper, we will address design concept of the transmission layer of the proximate space links for Korean lunar project.

To be operated, an SAR platform usually loaded on moving platform such as aerial vehicle or satellite then transmits and receives microwave signal for its own illumination sources. Space-borne SAR that is operated on space orbit uses ionosphere and air as a propagation medium. When linearly polarized microwave which conventional SAR system uses traverses thorough ionosphere, the reference plane of polarization rotates eventually causes polarization mismatch. To reduce the polarization mismatch, this paper proposes circular polarization on SAR sensor.","PeriodicalId":299228,"journal":{"name":"2014 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121991368","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}

It is interesting, however, 3-D sound cannot be scientifically well defined. The sensation of 3-D sound can vary with listeners and reproduction environments. To tackle this problem, an interface that can implement the desired 3-D sound in space and time by the listener is proposed. The interface, called “Spatial Equalizer”, controls the sound field using a point or multiple points related with the location of the virtual sound source. The user controls the points and listens to the sound until it is satisfactory.","PeriodicalId":299228,"journal":{"name":"2014 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"365 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125061356","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}

An ISP CDN provides the possibility of optimizing the content traffic in an ISP network, leaving opportunities for further optimization of content traffic among ISPs. CDN interconnection (CDNI) is being introduced at IETF as one of the most feasible solutions to reduce Internet exchange (IX) traffic by federation of multiple CDNs. It defines CDNI to be capable of interconnecting heterogeneous CDNs. We implement an IETF standard-capable CDNI gateway and conduct a CDNI field trial with two major ISPs of South Korea. In this paper, we show how the CDNI gateway interconnects between ISP networks and analyze the traffic reduction rate of CDNI systems on the IX traffic. According to our analysis on the result, CDNI can reduce more than 40% of content traffic on the IX point compared to legacy CDN systems.","PeriodicalId":299228,"journal":{"name":"2014 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"247 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123108923","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}
