Researches on service provisions for users over the ubiquitous computing environment have been started. The implementation method of an actual service, based on our proposed service-provision framework, is described in this paper. The service is a context-aware content-provision service. Through the implementation experience of the service, three issues are reported in this paper that are generally important for services in a ubiquitous computing environment. The first issue is that there is a difficulty in handling information in the community in ubiquitous computing environments unlike traditional Internet-based communities. The second issue is that the context-handling mechanism is important in ubiquitous computing environments. The third issue is that the system designer must consider the dynamic device-allocation facilities in the system.","PeriodicalId":220913,"journal":{"name":"2005 Symposium on Applications and the Internet Workshops (SAINT 2005 Workshops)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115539029","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 basic auction format can be augmented by various price features: the First Bidder Discount is one example. In a First Bidder Discount auction the bidder receives a discount on the price to pay if the bidder was the first to place a bid. The objective of this paper is to analyse this mechanism and to present a theoretical model describing the rules of a discount auction. Furthermore, an analysis of bidder behaviour and the timing of bids in internet auctions that include an added discount is investigated.","PeriodicalId":220913,"journal":{"name":"2005 Symposium on Applications and the Internet Workshops (SAINT 2005 Workshops)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128532643","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 this paper, we propose a distributed system based on authentication and access control agents characterized by autonomic policy decision, network federation and dynamic access control for context-aware services. We will describe the travel navigation service system implementation as one of the context-aware services and also report unresolved issues, which include network mobility support, trust relationship among agents and device interconnection.","PeriodicalId":220913,"journal":{"name":"2005 Symposium on Applications and the Internet Workshops (SAINT 2005 Workshops)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133122100","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}

Consequently, new devices are appearing requiring more and more IP addresses. This is the situation present around the home/industrial automation and in general remote monitoring. Nowadays more homes and buildings are entering into the future thanks to the appearance of control technologies that allow that a group of devices could work all together to provide the automation of the place. But each of these devices needs an IP address to communicate with the others and to be able to be contactedfrom outside. The actual version of the Internet Protocol (IPv4) has an important limitation in terms of the number of IP addresses for these new uses of the Network. IPv6 offers the solution of this situation, because it increases them exponentially, and facilitates a lot of new very interesting features for these scenarios. In this environment come out the 6-Plug system that allows a secure IPv6 access to your home and industrial automation devices. It is based on the UPnP (Universal Plug & Play) technology to discover and control the devices distributed across the local network.","PeriodicalId":220913,"journal":{"name":"2005 Symposium on Applications and the Internet Workshops (SAINT 2005 Workshops)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125856909","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}
