The multiplayer game is based on game theory and cryptographic puzzles. We divide requests from nodes into separate groups which decreases the ability of malicious nodes to cooperate with one another in order to effectively make a DDoS attack. Finally, through our experiments we have shown that the total overhead of the multiplayer game as well as the the total time that each node needs to be served is affordable for devices that have limited resources and for environments like ad hoc networks where nodes must exchange information really fast.","PeriodicalId":68078,"journal":{"name":"无线互联科技","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73191351","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, it is not easy to make a compact MIMO antenna for portable terminals, keeping high performance. One of the problems is mutual coupling among the antennas. This reduces the efficiency of the antenna. In this paper, a 3 dB hybrid is used to cancel the mutual coupling. This idea can be applied to 2N (N is integer) number of MIMO antennas. In addition, by using tunable impedance matching circuits, wide operational bandwidth is available.

On this purpose a Wireless Sensor Network (WSN) ZigBee based has been deployed in a specific indoor context. Three different RSSI measurement campaigns have been carried out to characterize the main propagation features. On the basis of the experimental results it has been possible to analyze the different factors that affect the measurements, such as external factors (e.g. multipath, fading) or internal ones (e.g. hardware device, integrated antennas). The first campaign, made nearby the transmitter, was performed to study the internal and external factor effects, the second one to extend the range of the first experiment, and the latter to investigate the propagation trying to isolate the external phenomena. Furthermore to deeply analyze the ZigBee behavior we have compared the measurements with a suitable propagation model.

Prolonged episodes of hyperglycemia elevate the risk of the patient developing diabetic complications, which makes infections such as common cold, influenza and influenza like illness more harmful for T1DM patients than the normal population. TTL, NST and AAU are researching a method of predicting illness in T1DM patients, using patient observable parameters. Daily BG measurements are identified as a relevant patient observable parameter, due to early rise when infected and elevated HbA1C during illness. A Smartphone based system is developed that allows patients to monitor BG concentrations and report symptoms of illness and illness. Data gathered by patients through use of this device, will be used to test the hypothesis that changes in daily BG measurements can be used to predict illness in T1DM patients, before symptoms onset. A successful prediction model will enable patients to get early indication of upcoming illness, before they are bedridden. Patients can thus actively take precautions to avoid or shorten illness episodes or make these less severe and/or have healthy BG concentrations during illness. This project is breaking new grounds by detecting illness before the onset of symptoms and illness, and an illness prediction model using patient observable parameters will be an important advance in the field of disease surveillance and prediction.","PeriodicalId":68078,"journal":{"name":"无线互联科技","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86912599","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 is expected that the opening of those frequency bands to the consumer market will lead to a dramatic increase of spectrum exploitation efficiency in highly appealing frequency bands: In Europe, the frequency bands between 470 MHz and 790 MHz are considered and the inherent signal propagation properties are largely superior to those in standard cellular bands, for example, in 900 MHz and 2 GHz. This paper will present related use cases for the exploitation of TV White Space as they are currently discussed in the ETSI Reconfigurable Radio Systems Technical Committee. Then, the availability of TV White Spaces in Europe is investigated, followed by an overview of recent regulatory activities on the European Commission level. In particular, expectations related to a new revision of the European R&TTE Directive are presented which represents the basic regulatory framework in Europe.","PeriodicalId":68078,"journal":{"name":"无线互联科技","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79096489","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}
