In traditional systems of this domain, only the location information of a user on \"one\" side of the watching site or the watched site is considered. In this work, we cope not only with the user's location but also all the detailed situations (contexts) of associated entities such as devices, software, networks, and users, in \"both\" sides. To do this, we propose a ubiquitous watching over system \"uEyes\". In uEyes, autonomous decision making ability and cooperative behavior are introduced to each entity. Based on the advanced feature of the entities, live video streaming system is dynamically constructed according to the contexts of the entities, on both sides in runtime. As a result, watching over service that fulfills detailed users' requirements can be effectively provided. We implemented a prototype of uEyes for watching over elderly people, and performed some experiments based on several scenarios. For instance, we assumed a scenario that a son, who is taking care of his ailing father, wanted to see his facial color and expression in high quality video. We confirmed that the live video streaming system involving high resolution camera and display devices is dynamically configured in run-time","PeriodicalId":440345,"journal":{"name":"2007 International Symposium on Applications and the Internet","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124861258","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 bandwidths of several wireless networks are asymmetric and restricted. For example, for the asymmetric link, 1x EV-DO specifies the peak rates for downlink and uplink as 2.4 Mbit/s and 153 Kbit/s. A header compression scheme for the transmitted packets of conversational multimedia signals is an effective solution for these scarce links, especially in the IPv6 environment. However, ways to improve the performance of the header compression scheme have not been thoroughly evaluated quantitatively considering the quality of conversational multimedia services over the asymmetric wireless links where the transmission characteristics of the up and down links are quite different. This paper presents the results of a study that examined ways to improve the performance of the header compression scheme based on control of the header compression parameters considering speech quality over the asymmetric wireless link. The paper also presents experimental verifications of the efficiency of our proposal using a practical implementation","PeriodicalId":440345,"journal":{"name":"2007 International Symposium on Applications and the Internet","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129302645","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}

In developing such a system, it is necessary to estimate the influence and the movement of its users and to get feedback. However, it is difficult to perform tests on such a system given the large number of human subjects involved and its scale, which matches that of a major city. One possible solution is proposed herein, the augmented experiment; it combines a multiagent simulation with a small-scale experiment performed with human subjects. In the experiment, the movements of agents that simulate users are shown to human subjects in order to give them the impression that the environment is populated with a large number of users. In this research, we build an evacuation guide system based on GPS-capable cellular phones and perform an augmented experiment wherein human subjects and evacuee agents are directed while the status of the simulation is passed to the human subjects. Interviews of the human subjects confirmed that the augmented experiment successfully gave the impression that a large number of users were present","PeriodicalId":440345,"journal":{"name":"2007 International Symposium on Applications and the Internet","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115154701","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}

Viruses should be considered a society-level security risk. However, the mainstream approach to addressing a virus is basically to implement countermeasures for the virus after the damage has occurred. Some of these countermeasures are unable to keep up with the current pace at which viruses are occurring. To address this problem, in this research, we developed a system to generate unknown virus extermination software automatically, without any manual operations. The developed system is designed to automatically generate software that detects and exterminates an unknown virus, by using both a dynamic heuristic that uses a virtual PC and a technique to automatically generate a signature from header data in the virus executable. We were able to verify the effectiveness of this system when we conducted experiments to check whether or not an actual virus could be exterminated by a vaccine that was automatically created for the virus with the developed system","PeriodicalId":440345,"journal":{"name":"2007 International Symposium on Applications and the Internet","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125000525","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}
