The secondary users operating on the same band used by primary user, so the QoS of primary user should be guaranteed. Eavesdropper can intercept the information transmission from the secondary transmitter or relay to the corresponding receiver, which is considered to threaten the security of cognitive radio networks. Finite buffer size is assumed to be available at the relay, so that the relay can store packets. We propose a max-ratio link selection scheme which can optimize the secrecy transmission performance by considering all possible source-to relay and relay to destination links and selecting the relay having the link which maximizes the signal to eavesdropper channel gain ratio. It incorporates the instantaneous strength of the wireless links as well as the status of the finite relay buffers and adapts the relay selection decision on the strongest available link by dynamically switching between relay reception and transmission, so it can take full advantage of the additional flexibility offered by relays with buffers. A closed-form expression for the secrecy outage probability is obtained, both simulation and theoretical results are shown based on the Markov chain to validate the proposed schemes and demonstrate that the proposed schemes can significantly enhance the secure performance compared to the conventional Max-min relay selection schemes.","PeriodicalId":124485,"journal":{"name":"2015 IEEE International Conference on Computer and Communications (ICCC)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122302241","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}

There are three evaluation metrics: Peak Signal to Noise Ratio (PSNR), structural similarity (SSIM), and encoding time, which were introduced to compare the three video encoders comprehensively. Each video sequence has 250 frames, and their resolution is 1920×1080, differing in spatial and temporal complexity. An extensive range of video content complexity were selected in the video sequences. Objective quality evaluation based on the calculation of spatio-temporal activities is tested to validate its suitability as video content complexity indicator in quality assessment. According to the analysis of experiment results, all the encoded modes present an obvious same trend. On a fixed video resolution and bit rate, with the video complexity increasing, the objective quality is decreasing and the encoding times is increasing. It was also concluded that the objective quality of X265-slow is far better than other encoder modes of X264 and VP9. In terms of encoding time, the encoding time of H264 was shown to be less than both HEVC and VP9.","PeriodicalId":124485,"journal":{"name":"2015 IEEE International Conference on Computer and Communications (ICCC)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128619853","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}
