Conventional channel estimation methods require that a pair of stations tune to the same channel, and then estimate the channel gain by transmitting some pilot signals. These methods are thus time-consuming and inefficient in multi-user cognitive radio networks. Moreover, wireless channels are affected by the small-scale fading. A one-time sample of a channel gain is thus noisy, and the small-scale fading would lead to estimation errors. In this paper we propose a kernel-based channel gain estimation method. We adopt the support vector regression to build the knowledge between the location information of each station pair and the corresponding channel gain. Such a kernel-based method is noise-resistant and time-saving. We perform a real-world experiment to measure GSM signals, and use the measurement to evaluate the performance of the proposed channel gain estimation method. Experiment results show that the proposed method with sufficient training data could achieve the root mean square error of channel gain estimation as low as 2 dB.","PeriodicalId":391671,"journal":{"name":"2011 International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125526406","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 major difference between VSN and ordinary sensor network is the large amount of data. In VSN, a large number of camera nodes form a distributed system which can be deployed in many potential applications. In this paper we present a model of the physical parameters of a visual sensor network to track large birds, such as Golden Eagle, in the sky. The developed model is used to optimize the placement of the camera nodes in the VSN. A camera node is modeled as a function of its field of view, which is derived by the combination of the lens focal length and camera sensor. From the field of view and resolution of the sensor, a model for full coverage between two altitude limits has been developed. We show that the model can be used to minimize the number of sensor nodes for any given camera sensor, by exploring the focal lengths that both give full coverage and meet the minimum object size requirement. For the case of large bird surveillance we achieve 100% coverage for relevant altitudes using 20 camera nodes per km2 for the investigated camera sensors.","PeriodicalId":391671,"journal":{"name":"2011 International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132758918","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 fact, although complex computational tasks still require server side resources, combination of rich content delivering devices, such as smart phones, together with wearable I/O devices and wireless broadband networking, can be used to seamlessly weave a mesh of client side and server side services. In this paper we describe how we leveraged such a set up to design and build a system capable of mitigating the negative effects of stress on the memorization capability of humans. Our system is able to capture user needs and to-dos, to infer where those needs and tasks can be efficiently fulfilled/performed and to provide timely and localized hints about the identified sweet-spots. Furthermore we evaluated innovative ways to drive the user to the most convenient site. We describe our system and a modular design both on the client and on the server sides, illustrating preliminary experiments performed both in laboratory and with real users, and we analyze the results.","PeriodicalId":391671,"journal":{"name":"2011 International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126592916","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}
