Based on the mobility prediction, bandwidth is reserved for the paths with the maximum support or the best confidence rule, so that the handoff calls' service can be guaranteed. This new approach belongs to the direct group mobility (DGM) prediction scheme and is based on the tree path construction algorithm (TPCON) for each base station (BS). The nodes with DGM support provide the BSs with the important aggregate bandwidth information so that they can avoid the congestion for the handoff users' sake. For finding the most popular group path, based on TPCON, clusters are constructed according to the various flows of the group mobility over an area of mobile stations. We focus on the center oriented clusters that are very crucial for bandwidth prediction purposes. An adaptive clustering algorithm creates the chain of activated cells at each time. A call admission control (CAC) algorithm is developed for each BS for minimizing the call dropping probability. This study deals with the system behavior only at exceptional congestion time periods (periodical events).

In this paper we analyze the major sources of complexity in the framework of network organizations, pointing out the necessity to give support to the user in many different ways and at very different levels of granularity, from the use of a single tool, to the management of whole, distributed, KDD projects. Unfortunately, currently available systems lack to support the users in at least some of these features. We then propose a solution based on the service oriented computing paradigm, arguing that the advantages of this paradigm, namely openness, modularity, reusability and transparency, as well as ubiquity, can help in the design of an effective support system for knowledge discovery in databases in network environments","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126150139","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}

They seek to leverage technology to enable teams to work together more effectively. But as issues faced by distributed teams today become more information sensitive and change more rapidly, they also bring to life a new set of requirements for collaboration technology. These requirements cannot be addressed by traditional application development efforts, as their costs and long development cycles make them prohibitive. Nor can they be addressed adequately by general collaborative tools such as email and groupware. This paper introduces a new paradigm in developing and deploying collaboration applications for the more lightweight, task-oriented requirements that sometimes comprise the majority of a team's activities. It conjectures that in these situations, it is feasible, and in fact, necessary for end users, even without software training, to directly create and implement such applications themselves. This paper further outlines a new development framework to put this paradigm in action. And finally, this paper briefly discusses an ongoing project to enhance the Air Force's KnowledgeKineticstrade (K2 ) portal with a set of portlet design tools based on this framework","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131040365","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}

User participation in collaborative activities requires mechanisms to support dynamic group membership and maintenance of perpetually changing delivery topologies. In the past, multicast support has been studied within testbeds such as the MBone, and across overlay architectures. In this paper we tackle the problem of how network-native multicast can help to orchestrate the formation of virtual teams in group collaboration. We argue that user interaction can be understood as a series of constraint-driven information exchanges, for example by sharing objects based on access rights. A novel multicast protocol, limited core fix (LCF), is introduced to efficiently maintain multicast delivery trees among distributed work teams. LCF is a receiver-centric mechanism to support qualification-based multicast routing and performs more efficiently than comparable existing protocols","PeriodicalId":283620,"journal":{"name":"Proceedings of the 2005 International Symposium on Collaborative Technologies and Systems, 2005.","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116810278","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 solutions to these challenges are forcing the warfighter to assimilate and process vast amounts of information from a broad spectrum of domains. The global information grid (GIG) provides the global connectivity for the information to get to where it's needed, however the information need to be processed and converted to knowledge to empower the warfighter to succeed. Bringing this information together in a comprehensible fashion has driven the military to a new approach to warfare, a network-centric warfare (NCW) approach - also called network-centric operations & warfare (NCOW) by the air force community.
