The distance of a tag from the reader remains unknown. However, more precise location information of objects provided at low cost is critical to create smart spaces. In this paper, we present a distance-sensitive RFID system that accurately resolves a tag's distance from the reader. In contrast to other distance sensing systems that operate on the emission of electromagnetic waves, high frequency RFID systems make use of magnetic coupling for data transmission. The paper details the system design and implementation with discrete components, presents the distance measurement procedure, and evaluates the accuracy of the measurements.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128746194","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 iceberg cubing problem is to compute the multidimensional group-by partitions that satisfy given aggregation constraints. As we know, there has been no algorithm that computes iceberg quotient cube for nonantimonotone aggregate functions. In this paper, we propose a new structure hyper-star-tree and an efficient algorithm, called IQ-Cubing, for iceberg quotient cubing with nonantimonotone aggregation constraints. We also employ the closedness measure to do pruning efficiently and utilize the closed mask to help the formation of equivalence classes. We conduct an investigation into the performance of our ideas and techniques.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125831429","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}

These systems allow for automatic and distributed monitoring of patients, but many of them are time consuming with regards to installation and maintenance configuration of the sensor network and communication platform. To avoid burdening caretaking staff and relatives with installing and configuring system software and hardware, a research project at the Engineering College of Aarhus, pervasive healthcare lab, has been trying to achieve a zero-configuration solution, removing most handling while at the users home. Achieving a true zero-configuration strategy has proven hard to implement especially with regards to the coupling of the individual wireless sensors to a specific patient. This paper discusses the experiences gained so far with developing a prototype solution, including how zero-configuration was originally conceived, which problems were identified, and which solutions are being tested.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125956457","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}

An innovated business application integration pattern for collaborated enterprises with the traits of the variability and equality was presented, in which the key challenge is that there is not the need of a headquarters to govern the whole business across the enterprises with the common business processes. According to the requirements derived from this innovated pattern, a service-oriented business rule-based application platform in pervasive computing environments was proposed and some key challenging issues were researched in this paper. The architecture design of the application platform exploits service-oriented architecture and business rules-based approach to enhance the flexibility, scalability and dynamic adaptability of the business application. Business rule-based approach enables the application agilely adapt to the changeable market in both the level of service and service collaboration with the separated deployable rules. The implementation experience of a prototype has verified the feasibility of the proposed architecture in the pervasive computing environments.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126159181","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 paper presents a framework to facilitate dynamic service composition, selection and adaptation of QoS-aware Web services towards pervasive computing. Considering both functional and QoS characteristics of Web services, this framework intends to generate the optimal travel process solutions for tourists in spite of their locations. For many Web services providing a similar functionality, our study primarily focus on the issue about services selection with multi-constraints. In this paper, we propose a heuristic algorithm on the multi-choice, multi-dimension 0-1 knapsack problem (MMKP) using the rule-library. Finally we test the efficiency of the algorithm and the results prove it is predominant compared with other algorithms.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124193153","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 context, various QoS descriptive frameworks and Web services technologies (such as WSDL and BPEL) are being considered as the most affordable solutions to promote the performance of decentralized e-services, through applying strategies like QoS ontologies and related optimization algorithms globally or locally. Nonetheless, most P2P-based service selection and composition approaches applied nowadays lack dynamism and autonomy. In this paper, we first propose an extension of non-functional properties in WSMO, so that to globally facilitate dynamism and autonomous coordination in service compositions. Furthermore, taking into account a model driven approach, we design a planning algorithm to intelligently assign composition tasks to the most appropriate peers for different steps in a whole process.
