The key building block of a VoIP gateway is a telephony card that interfaces with the PSTN and converts signals from the PSTN to bits that can be manipulated by a computer and vice versa. Because commercially available telephony cards only work with wired PSTN lines, almost all existing VoIP gateways are tethered and therefore do not support the kind of mobility enabled by modern wireless communications technology. This paper describes the implementation and evaluation of a mobile VoIP gateway called WGate that is designed specifically to bridge wireless VoIP clients and cellular phones, and can thus be easily deployed on demand in particular geographical locations. The key innovation of WGate is the ability to use a Bluetooth link as a wireless backplane by exploiting the Hands-Free profile of the Bluetooth protocol stack and eventually turning a set of commodity bluetooth-capable cell phones into a multi-port telephony card. Empirical measurements on a working prototype show that this approach can scale a VoIP gateway up to 8 cell phones because state-of-the-art Bluetooth adapters can only support up to 8 simultaneous Synchronous Connection-Oriented (SCO) connections when they operate in physically close proximity.","PeriodicalId":163002,"journal":{"name":"2009 6th Annual International Mobile and Ubiquitous Systems: Networking & Services, MobiQuitous","volume":"94 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124397279","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}

However, general device-control point approaches are not suitable for wireless sensor networks due to severe resource constraints and gateway architecture. To alleviate the problems we change discovery processes: 1) sensor node announces uniquely assigned identifiers; 2) base station retrieves additional descriptions for sensor nodes using lookup facilities; and 3) control points communicate with the base station to browse a list of descriptions and to send control commands to sensor nodes via standard UPnP protocols. In this paper we introduce our description lookup-based UPnP extension system for wireless sensor networkds.","PeriodicalId":163002,"journal":{"name":"2009 6th Annual International Mobile and Ubiquitous Systems: Networking & Services, MobiQuitous","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117146892","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}

Falling accidents could cause major injuries, such as having bruise, breaking bone, and in the worst case, losing life. Therefore, preventing elders from falling accidents is important in order to ensure the quality of life. In this paper, we propose Fatigue Alerting SHoes (FASH), a pair of shoes which detects the fatigue of walking people. There are three effects of fatigue on gait, and FASH system acquires all of them to improve the accuracy of fatigue detection. FASH system uses pressure sensors embedded in a pair of shoes to detect the tiredness, and notifies the user of “Tiredness Scale,” a scale we defined in order to show the degree of tiredness. Through the evaluation, we affirmed the availability of using pressure sensor to detect accumulation of tiredness. We also confirmed the difference between the physical tiredness and the subjective feeling toward tiredness, which signifies the importance of acknowledging the user of his/her fatigue.","PeriodicalId":163002,"journal":{"name":"2009 6th Annual International Mobile and Ubiquitous Systems: Networking & Services, MobiQuitous","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126144501","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 importance of ‘devices around’ as a context has been highlighted many times, to the best of our knowledge, there is no systematic mechanism reported to identify and capture this context. In this paper we report our mechanism for extracting patterns that we call co-locators from the surrounding Bluetooth devices. The co-locator context can then be used as an indication about the user's surroundings. The context can be directly associated with user behavior in the surroundings, which in turn can be used for recommendation purposes. The context can also be used as a supplemental location indicator in the absence of other location mechanisms such as GPS. We then show that our experimental results support the value of using extracted co-locator patterns as good supplemental location indicators for several applications.","PeriodicalId":163002,"journal":{"name":"2009 6th Annual International Mobile and Ubiquitous Systems: Networking & Services, MobiQuitous","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126809681","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 can result in several problems, especially for home monitoring and hospital scenarios, where easy, fast, and accurate association of pre-determined devices is needed. Due to the rapidly changing environments in these scenarios, however, association schemes are required that allow ad-hoc associations of pre-determined devices in this context. In this paper, we describe the problems for this particular scenario with respect to the current standard methods of association and present multiple solutions to alleviate the problems encountered.

Although, monitoring was the initial application of wireless sensor networks, in-network data processing and (near) real-time actuation capability have made wireless sensor networks suitable candidate for event detection and alarming applications as well. Unreliability and dynamic (e.g. in terms of deployment area, network resources, and topology) are normal practices in the field of WSN. Therefore, effective and trustworthy event detection techniques for the WSN require robust and intelligent methods of mining hidden patterns in the sensor data, while supporting various kinds of dynamicity. Due to the fact that events are often functions of more than one attribute, data fusion and use of more features can help increasing event detection rate and reducing false alarm rate. In addition, sensor fusion can lead to more accurate and robust event detection by eliminating outliers and erroneous readings of individual sensor nodes and combining individual event detection decisions. In this paper, we propose a two-level sensor fusion-based event detection technique for the WSN. The first level of event detection in our proposed approach is conducted locally inside the sensor nodes, while the second level is carried out in a level higher (e.g., in a cluster head or gateway) and incorporates a fusion algorithm to reach a consensus among individual detection decisions made by sensor nodes. By considering fire as an event, we evaluate our approach through several experiments and illustrate impact of sensor fusion on achieving better results.","PeriodicalId":163002,"journal":{"name":"2009 6th Annual International Mobile and Ubiquitous Systems: Networking & Services, MobiQuitous","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122293270","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}
