In recent times, spectrum sensing has been intensively studied as a key technology in realising the cognitive radio. In this paper, we consider an amplify-and-forward relay-based cooperative spectrum sensing using a double threshold energy detector. Each secondary cognitive user takes a local decision on spectrum occupancy based on two energy detection thresholds. If it detects the value out of both thresholds, it makes a decision first, amplifies and forwards the local result to the fusion center. If the detected value falls between the both thresholds, it amplifies and forwards this detected value to the fusion center. Finally, energy fusion and decision fusion are conducted at the fusion center to determine the primary user status. Cooperative probability of detection, probability of missed detection and probability of false alarm are derived theoretically with and without direct communication between the primary user and fusion centre. Simulation results show that the proposed method achieves an improvement in probability of detection.","PeriodicalId":193597,"journal":{"name":"2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA)","volume":"166 15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121026457","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}

With Tor, the users are able to compromise the non-repudiation principle of computer security. Also, the potentially hackers may launch attacks such as DDoS or identity theft behind Tor. For this reason, there are needed new systems and models to detect or identify the bad behavior users in Tor networks. In this paper, we present the application of Neural Networks (NNs) and Friedman test for user identification in Tor networks. We used the Back-propagation NN and constructed a Tor server, a Deep Web browser (Tor client) and a Surface Web browser. Then, the client sends the data browsing to the Tor server using the Tor network. We used Wireshark Network Analyzer to get the data and then used the Back-propagation NN to make the approximation. We present many simulation results for different number of hidden units considering Tor client and Surface Web client. The simulation results show that our simulation system has a good approximation and can be used for user identification in Tor networks.","PeriodicalId":193597,"journal":{"name":"2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA)","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114258984","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}

But this algorithm generates a lot of redundant packets, thus wasting unnecessary network resources and packet delivery energy. Researchers have then presented two solutions, Redundant Link Minimization (RLM for short) and Redundant Link Minimization-Triangle (RLM-T for short), to mitigate the mentioned phenomena. But both algorithms still have their own problems, e.g., many redundant packets still exist, meaning that the established routing-path can be further optimized. Therefore, in this paper, we propose an improved version, called the Cluster-based Redundant Link Minimization scheme (C-RLM for short), with which an event-driven wireless sensor network (EDWSN for short) can build its routing paths with less control packets and lower energy consumption than those of the two. Experimental results show that this method can effectively improve an EDWSN's throughputs and mitigate its packet delivery energy consumption.","PeriodicalId":193597,"journal":{"name":"2015 10th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129040376","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}
