Realization of this kind of communications is important to deploy IPv6. However, many almost of commercial video conference systems do not work in IPv6 networks. We developed an application gateway called as \"PTGATE\" to extend available scenes of video conferences. PTGATE has three functions: IPv4 over IPv6 tunneling to use video conference systems for IPv4, multicast tunneling over unicast networks, and error recovery using FEC. By using PTGATE, the current resources of video conferences correspond to various network environments. In this paper, we describe the overview of PTGATE and its evaluation. Also, we show practical experiments of PTGATE using actual networks","PeriodicalId":297153,"journal":{"name":"International Symposium on Applications and the Internet Workshops (SAINTW'06)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131997235","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}

To handle the large number of information and queries communication devices issue, some scalable mechanism must be required. In this paper, we propose a peer-to-peer network system called \"Mill\" which can efficiently handle information related to the geographical location. To simplify the management of the location related information, we convert two dimensional coordinates into one dimensional circumference. Using this technique, Mill can search information by O(log N). Some DHT networks achieve the same performance. However, DHTs support only exact match lookups. The exact match is not suitable for searching information of a particular region. Mill provides an effective region search, by which users can search flexibly location-related information from small regions to large regions","PeriodicalId":297153,"journal":{"name":"International Symposium on Applications and the Internet Workshops (SAINTW'06)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133057786","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 discovery and delivery of the most relevant and suitable services in a spontaneous network is a problem of paramount importance.

At the heart of the architecture is the muJini proxy which mediates the discovery and delivery processes. Its delivery subsystem provides thin-client based adaptation for fat service delivery that does not fit into thin client devices.

The compressed HDTV system provides high quality audio and video with relatively small bandwidth comparing with uncompressed HDTV system, but it suffers about 1 second delay for MPEG2 encoding and decoding. Its high quality video and audio enables applications such as remote lecture/seminar with limited interaction. Using compressed HDTV system, we had two-way experiment which requires 40-50Mbps bandwidth in Gigabit IPv6 network in dual stack mode.

Strict RFID regulations and standards have been imposed, trying to address the problem of reader collision and also the problem of RFID devices interfering with other devices operating in nearby frequency bands. However, these guidelines and regulations are not entirely friendly for dense RFID reader deployment, in some cases it is not possible to have a feasible RFID system while adhering to these regulations. Hence, this paper proposes the synchronization of RFID readers, to enable successful dense RFID reader deployment. A case study targeted at European operations is presented in this paper to visualise the actual synchronization of RFID readers in real life applications.

When the transmissions from one reader interfere with the operation of another reader, a reader collision occurs. The objective of the reader collision problem is to minimize the reader collisions experienced by RFID readers while using the minimum number of frequencies and using the minimum total time for all readers to communicate successfully. HiQ attempts to minimize reader collisions by learning the collision patterns of the readers and by effectively assigning frequencies over time to ensure neighboring readers do not experience collisions from one another. HiQ is arranged hierarchically with distributed, local control. The algorithm is based on a type of reinforcement learning called Q-learning, which is used to determine frequency and time assignments. Through repeated interaction with the system, Q-learning attempts to discover an optimum frequency assignment over time. We show that HiQ finds optimal or near optimal solutions to the reader collision problem.","PeriodicalId":297153,"journal":{"name":"International Symposium on Applications and the Internet Workshops (SAINTW'06)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130444134","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}
