A Federation of Personal Networks (Fednet) is a peer-to-peer cooperation of PNs of different users to share personal resources and services. Until now little research has been conducted on the service provisioning in Fednets. Based on the current status of the research on Fednets, the service provisioning can be done directly at the personal device (network overlay approach), or at a specific entry point of a PN, called a service proxy (service proxy approach). While the network overlay approach provides quick service access and provisioning, the service proxy approach provides a more elegant solution for service provisioning by preventing direct access of other PNs to the PN’s services and by enabling the control over the access to personal services at a single point of a PN. In this paper, to leverage the advantages of both approaches, we propose a hybrid approach to service provisioning in Fednets, which combines both approaches to provide an optimal and flexible solution for service provisioning in Fednets.","PeriodicalId":150024,"journal":{"name":"2009 Third International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115180850","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}

Home automation and wireless sensor networks, as ubiquitous integrations of technology and services at home, are enhancing the quality of life by improved security, information and comfort. We have defined a centric UbiHOMESERVER with three main roles: use of existing interfaces on proprietary systems for remote monitoring and control, serving the surrounding system as a data gateway and providing content-adaptive user interfaces optimised by properties of end-user client devices. Throughout the entire environment, the goal of user interface design is to keep the interaction experience of an end-user as simple and intuitive as possible. In this paper, we present the design of a medicine dose controller, which is our on-going research and development prototype aiming to accomplish this goal. As a ubiquitous device, UbiPILL is targeted to people having problems in remembering to take their medicine on time. Having elderly people in mind, a seamless interoperation between UbiPILL and UbiHOMESERVER has been designed to reliably monitor the medicine box activities by a web browser of any client device.","PeriodicalId":150024,"journal":{"name":"2009 Third International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124746384","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}

We evaluate the performance of three prediction algorithms, namely, ARIMA, Linear regression and NFI, based on the data sets collected from diverse real-life network environments. Later, we apply the network prediction algorithms to adaptive file download, and compare their effectiveness in terms of energy savings. The results show that the adaptations using prediction could save up to 14.7% more energy when compared to prediction-less adaptation.","PeriodicalId":150024,"journal":{"name":"2009 Third International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies","volume":"504 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113999505","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}

Pervasive computing is aimed to eliminate time and place barriers by making services available to users anytime and anywhere. Due to the numerous numbers of services which are available in pervasive environments, the presence of service discovery is a necessity to help users to discover and utilize their desired services. However, tackling security issues such as preserving transferred information reliable and private, in service discovery process in pervasive environments is a demanding task. In this paper, we propose a secure framework to support service discovery in pervasive computing environments.

This paper proposes a multipath routing protocol LBR (Link lifetime based Backup Routing) to improve routing stability. LBR is based on link lifetime, while obtaining the shortest path between source and destination through flooding, and setting up a local backup path for each link in the primary path concerning link lifetime. This scheme effectively avoids backup paths being out-of-date and increases the availability of backup paths. Both theoretical analyses and simulation results show that LBR has an improvement in route lifetime, packet delivery ratio, end-to-end delay, and so on, compared with single-path routing protocols.","PeriodicalId":150024,"journal":{"name":"2009 Third International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129744449","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 the trial the pupils marked their arrival at and departure from the school by touching a reader device or NFC-enabled mobile phone with a smart contactless card. The system simplified attendance monitoring by replacing manual roll calls leaving thus more time for teaching. Parents were able to receive real-time information on children’s attendance, which reduced their concerns about whether their child had arrived at school safely. Information about user experience was obtained by using a variety of data collection methods. Children, as well as their teachers, became fast familiar with the touch-based interaction, and the attendance supervision was soon integrated into their everyday school routines. Our analysis shows that a technology-supported attendance supervision system can bring value for all end-user groups but it seems that the system will serve primarily the teachers and the parents.","PeriodicalId":150024,"journal":{"name":"2009 Third International Conference on Mobile Ubiquitous Computing, Systems, Services and Technologies","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132767936","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}
