Smart buildings comprise a key part of smart spaces, where the provided services, such as climate and lighting control or security, can be offered intelligently if one considers the static and dynamical status of the building and the location of residents. This work is focused on providing an autonomous system capable of collecting a wide range of monitoring information to ensure a comfortable atmosphere in a building and assist residents with smart automation. Location plays an important role in many context-aware applications and it is used in this work in the form of an adaptive localization mechanism based on RFID (Radio-Frequency Identification) and IR (Infra-Red) to implement a tracking system based on a Radial Basis Function Network and a Particle Filter, which is capable of providing location user with a low error. A theoretical study about models of transmission power losses in indoor environments has also been tackled, hence the number and position of sensors and the accuracy of measurements are optimized. A real scenario that exploits the capabilities of the system is described and used to gather results that demonstrate how this localization mechanism enhances the experience of users in smart buildings through a set of services.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"412 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123254023","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}

Unfortunately, it usually defines the data shared by these devices in a syntactic level, showing a lack of expressiveness. During the last decade, the Semantic Web (SW) has aimed to solve these problems by adding logic to the Web to make it machine-understandable and by therefore enhancing the interoperability of the applications using it. The SW is used in the Triple Space Computing paradigm, which proposes a blackboard model where semantically described knowledge is shared between different devices in a completely Restful, and consequently WoT compliant, manner. This paradigm's shared blackboard can be implemented using many strategies, from centralized to completely distributed. In this work, we compare and analyze the behaviors of these two extreme cases in several simulations which try to represent common IoT scenarios. Finally, we propose an improvement of the completely distributed strategy by enabling the gossiping between devices.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122553486","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}

Recently, with the dissemination of mobile devices to Internet connectivity, users can interact with sensor networks and collect environmental data, anytime, anywhere using user-friendly mobile applications. Following the Internet of Things vision, the integration of all sorts of Internet-based devices is considered a big challenge. New infrastructures are required in order to interconnect these devices independently of the used technologies. This paper proposes a model for WSNs monitoring based on a REST Web service and XML messages to provide a mobile ubiquitous approach for WSN monitoring. Data collected from a WSN is stored in a database. Then, mobile clients send XML based messages to a HTTP server through a well-defined REST interface, requesting WSN collected data. A WSN laboratory test bed was used to perform the evaluation, demonstration, and validation of the proposed model. Results show that proposed solution is able to collect and present data in a mobile environment, and it is ready for use.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128770090","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 examines how start-up enterprises achieve their operational success. Literature review and the case study method were applied to support the factors of sixteen enterprises within the Hsin-Chu Science Park. This research explore their entrepreneurial motives and opportunities, and factors on how to achieve entrepreneurial success in high-tech start-ups. The results showed the successful business model for start-up enterprises lies in scale economy, cost controlling, and after-sale service. The most concerned risks are in whether the customer relationship is steady and its avoidance of bad debts, while having enterprises also found more success when led by market opportunities rather than by new technologies. It is often agreed that innovation is the key for an enhanced economic performance. Thus, this paper aims at finding strategies entrepreneurial motives and opportunities, and factors on how to achieve entrepreneurial success for high-tech start-ups.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127928911","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}
