Scatternets expand its use to larger networks. If communication patterns are known before scatternet formation, frequently communicating pairs could be connected directly or with fewer hops to enhance performance. Communication patterns are obtainable by observing traffic, but this approach is ineffective in a pervasive computing environment where interactions are mostly spontaneous. We propose to use social group membership as an estimate of communication patterns. The proposed scatternet formation scheme forms a scatternet per a social group and then connects scatternets through tunnels. In order to ensure that each communicating pair has a reasonable share of bandwidth, the proposed scheme considers the number of hops and branches and traffic distribution when interconnecting scatternets. Simulation results show that the proposed scheme not only enhances the total throughput of scatternets but also shares network capacity more fairly among communicating pairs","PeriodicalId":352348,"journal":{"name":"Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131795826","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}

While the WWW offers a multitude of Web services there is a lack of search engines which support the users in finding adequate services out of the bulk of available Web services. Within this paper, we will introduce a context-sensitive approach for effective Web service discovery. As a huge amount of context information could be gathered by the use of mobile devices, this approach is especially directed towards users of these mobile devices. Examples for context information are the actual visited place, the actual temperature, the recent illumination, etc. Also communities of users who share common contexts, interests and service needs arise. While existing systems for Web service discovery generally do not consider context and community information of their users, we will focus on these topics, taking advantage of an novel adaption of information retrieval techniques","PeriodicalId":352348,"journal":{"name":"Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07)","volume":"47 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134329251","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 introduces a novel concept for data access management, called dual ownership. The model grants access control to parties that can prove the physical possession of an item. RFID technology hereby tracks the transitions of physical possession to translate them to data access permissions.

By enabling additional collaboration from stations that otherwise will not directly participate in the transmission, cooperative communications ushers in a new design paradigm for wireless communications. In this paper, we extend a cooperative MAC protocol called CoopMAC into the ad hoc network environment. The new protocol is based on the idea of involving in an ongoing communication an intermediate station that is located between the transmitter and the receiver. The intermediate station acts as a helper and forwards to the destination the traffic it receives from the source. Thus, a slow one-hop transmission is transformed into a faster two-hop transmission, thereby decreasing the transmission time for the traffic being handled. Extensive simulations in a large scale wireless ad-hoc network (150 stations) show that CoopMAC significantly improves the ad hoc network performance in terms of throughput and delay, and indicate how such cooperative schemes can boost the performance of traditional solutions (e.g., IEEE 802.11)","PeriodicalId":352348,"journal":{"name":"Fifth Annual IEEE International Conference on Pervasive Computing and Communications Workshops (PerComW'07)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124775277","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}

It provides a document-oriented applications model that eliminates the requirement for application providers to provide custom clients for their applications. Application providers compose interactive user interfaces through compound documents that specify content for a set of viewers, each oriented to a particular content medium. A viewer's content may define actions on other viewers. This approach offers the additional benefit of offering a higher-level model to application developers, hence reducing application development costs. Our current set of viewers is oriented toward the domain of telematics applications, and includes viewers for map features, HTML-based messages, sound clips, and ticker messages.
