The experiment of ``Super Hi-Vision definition TV\" has been studied over WINDS. Thus, it is expected that the use of such multimedia application over the satellite Internet will become larger. It is necessary for such applications to guarantee the throughput. QoS-TCP has been proposed to guarantee throughput by using a transmission control protocol. The traditional QoS-TCPs can obtain the required throughput by adjusting sending rate in response to the demand of application. However, the retransmission control of traditional QoS-TCPs is same as a normal TCP. If these methods are used over the satellite links which have large-bandwidth, long delay and packet losses, it is possible that these methods can not obtain the required throughput when packet losses occur. In this paper, we propose a control method for QoS-TCP, which moderates degradation of congestion window and accelerates the data transmission speed when packet losses occur. As a result, it is expected that the proposal can improve the QoS-TCP performance for guaranteeing the throughput. Simulation results show the proposal can obtain better throughput than the existing method over the typical satellite link which has bit error and coexists the background flows.","PeriodicalId":391671,"journal":{"name":"2011 International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116663904","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}

Recorded as 9.0 on the Richter scale, it was the most powerful quake ever to hit the country and caused severe damages over northern parts of Japan. This paper is discussed about the quick reports of communication traffic analysis and connectivity in the disaster area where electrity and network connection was survived. Then, our proposed Never Die Network in Disaster Information System is discussed with considering user policy from the reports. Just After the earthquake, network conditions were not enough to held multimedia communication because many network machines were damaged. However, it was very important to keep even minimal network connection to use Disaster Information System such as live, shelters, life line, and so on can be used. Our proposed Disaster Information System needs such a robust Never Die Network which will be provided the least transmission service even after severe disaster. Thus, we introduce Satellite System for optimal transmission control method in Cognitive Wireless Network in order to consider with severe disaster. First, as our previous study considering user policy, proper wireless link and route selection is held by Extend AHP and Extend AODV with Min-Max AHP value methods for optimal transmission control in Cognitive Wireless Network. Then, it is discussed about additional functions using satellite system in NDN. In the simulation, ns2 are used for the computational results to the effectiveness of the suggested transmission methods.","PeriodicalId":391671,"journal":{"name":"2011 International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121723563","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}

Thanks to the ubiquity of mobile computing devices and emerging cloud-based services, the users permanently stay connected to their data. This introduces a slew of new security challenges, including the problem of multi-device key management and single-sign-on architectures. One solution to this problem is the utilization of secure side-channels for authentication, including the visual channel as vicinity proof. However, existing approaches often assume confidentiality of the visual channel, or provide only insufficient means of mitigating a man-in-the-middle attack. In this work, we introduce emph{QR-Auth}, a two-step, 2D barcode based authentication scheme for mobile devices which aims specifically at key management and key sharing across devices in a pervasive environment. It requires minimal user interaction and therefore provides better usability than most existing schemes, without compromising its security. We show how our approach fits in existing authorization delegation and one-time-password generation schemes, and that it is resilient to man-in-the-middle attacks.","PeriodicalId":391671,"journal":{"name":"2011 International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128424797","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}
