This test can be considered as a result of a new approach to solving the Behrens-Fisher problem when covariance matrices of multivariate normal populations (compared with respect to their means) are different and unknown. The test makes use of an invariant statistic whose distribution, under the null hypothesis, does not depend on the unknown (nuisance) parameters. The sample size and threshold of the UMPI test are determined from minimization of the weighted sum of the model builder's risk and the model user's risk. The rules are proposed to identify an observable process with one of several rival models, suitable for modeling, which accurately represents the process, especially when decisions involving expensive resources are made on the basis of the results of the model. Application examples are given.","PeriodicalId":428618,"journal":{"name":"2011 Baltic Congress on Future Internet and Communications","volume":"242 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121248508","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}

Current service environments within the Internet are missing important capabilities like performance elasticity, scalability, reliability or seamless interoperability between service providers. The Internet has to become a more secure space enabling new approaches for Quality of Service and the service mobility to enhance the overall user experience. This paper is proposing a novel architecture to create network aware services. It refers to the existing standards of the next generation network technologies and specifies service environments. The elaborated architecture enables the mediation between network and service layer in order to maximize the capabilities of the connection. This cross layer approach combines the advantages of both layers like orchestration, discovery, context-aware routing or pure Quality of Service. The components of the architecture are presented in detail where a special focus lies on the Service Broker, which is key mediating component in this architecture. The paper concludes with an evaluation of a proof of concept prototypically implementation that illustrates the enhancement of the user experience by the idea of being “Always Best Connected”.","PeriodicalId":428618,"journal":{"name":"2011 Baltic Congress on Future Internet and Communications","volume":"37 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126673055","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}

With billions of sensors, there is an opportunity for new behavior from applications in mobile devices based on sensor input. But such applications require a mechanism to provide a manageable subset of sensors, relevant to the user's current situation; since no single device is capable of maintaining a list of billion sensors. By using a context enabled distributed storage of sensors; we can provide communication with a finite set of nodes that are deemed relevant to the user's current context. We introduce the notion of a sensor socket, that share API similarities to a TCP/IP socket, which provides communication with remote devices. We identify requirements on the grouping mechanism concerning connectivity to ensure reliable communication decoupled from location. We then provide a scenario for how sensor sockets could enable device connectivity. Finally, we demonstrate a subset of the scenario, with a proof of concept, by presenting ad-hoc association of a printing resource with a mobile device connected to the Internet via mobile broadband.","PeriodicalId":428618,"journal":{"name":"2011 Baltic Congress on Future Internet and Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129822011","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}

Currently there is no standardized reference model which can be used to compare and evaluate existing or design future Intrusion Handling Systems for Wireless Local Area Networks. Hence this paper describes and discusses the construction of Inter IHS Communication Subsystem Ontology of Intrusion Handling System's reference model. The proposed ontology is based on the concepts of various ontology modelling and simulation tools. Careful attention is given to support two important functions: manage the dependencies between ontologies and at the same time to keep and restore their consistencies if they change in order to accommodate new information, or to adjust the representation of the domain as the world changes.","PeriodicalId":428618,"journal":{"name":"2011 Baltic Congress on Future Internet and Communications","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121533463","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}
