The utility function for the game module considers both the receiving SINR threshold and transmitted power and tries to reduce interference as much as possible on the basis of guaranteeing the QoS demands for various services. The available channels can be evaluated through primary users occupying channel time and channel idle/occupied switching times. CR-BS (Cognitive Radio Base Station) calculates queue priority in a scheduling cycle based on users’ difierent services and dynamically adjusts service opportunities for realtime services and non-realtime services, which can provide difierential services and guarantee the equality for difierent services. The simulation shows that the proposed algorithm converges fast, can still ensures each user’s SINR value higher than its QoS demand threshold in low SNR environment, reduce the interference to primary users, and enhance network performance.","PeriodicalId":213716,"journal":{"name":"The Journal of Information and Computational Science","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130673583","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}

Firstly, we proposed a Scalable Uniform Localization Performance evaluated model (SULP evaluated model). There are two parts of this model, modules and data structures, both of them can be customized and extended by users as they need. By using this model researchers can save more time because they pay more attention to the algorithm itself but not to the evaluate environment and parameters. Secondly, we investigated the impacts of communications radius and anchor node ratio on localization algorithms. Four classical algorithms have been evaluated under the scalable model. Experimental results show that the performance including localization error rate, localization cover rate and energy consumption have difierent trends when communication radius and anchor node ratio changing in a reasonable range. Finally we concluded the regulars of the trends to provide instructions to industrial applications and other researchers.","PeriodicalId":213716,"journal":{"name":"The Journal of Information and Computational Science","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130258431","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 this case the main interference is the narrowband interference which comes from the GMR system. The paper researched the method of the narrowband interference suppression in the WCDMA satellite system. Furthermore, because the WCDMA system also contains a multi-access interference, the paper proposed a code-aided interference suppression technology, which can suppress both the MAI (Multiple Address Interference) and NBI (Narrow Band Interference), into the WCDMA satellite system to eliminate the GMR interference. Theoretic analysis and system simulation show that, the GMR signal interference can effectively be inhibited with a more mature and better MMSE (Minimum Mean Square Error) and ZF (Zero-force) code-aided technology, the co-channel transmission performance of the WCDMA systems can be protected well.","PeriodicalId":213716,"journal":{"name":"The Journal of Information and Computational Science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127819213","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}

Most existing motion segmentation algorithms based on subspace clustering operate in a batch fashion. The main di‐culty of applying these algorithms to real-world applications is that their e‐ciencies can hardly meet the speed requirement when dealing with video streams. In this paper, we propose an online motion segmentation method based on Sparse Subspace Clustering (SSC). Two strategies are adopted in our approach, namely the incremental Principal Component Analysis (PCA) and a warm start from previously obtained Sparse Representation (SR), to accelerate the dimension reduction and SSC in each trail. Through extensive experiments on both synthetic and real-world data sets, we conclude that our algorithm can achieve a signiflcant acceleration under a comparable misclassiflcation rate with respect to other state-of-the-art algorithms.","PeriodicalId":213716,"journal":{"name":"The Journal of Information and Computational Science","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129034377","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, fake reviews would mislead users. Therefore, detecting such reviews is an important task for safeguarding the interests of users. But the review sequence has been neglected by the former work. In this paper, we explore the issue on fake review detection in review sequence, which is crucial for implementing online anti-opinion spam. We first analyze the characteristics of fake reviews. Based on review contents and reviewer behaviors, six time sensitive features are proposed to find the fake reviews. And then, we devise two type of detection methods, the supervised and the threshold-based, for spotting the fake reviews as early as possible. Finally, we carry out intensive experiments on a real-world review set to verify the effectiveness of our methods. The experimental results show that our methods can identify the fake reviews orderly with high precision and recall.","PeriodicalId":213716,"journal":{"name":"The Journal of Information and Computational Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122027560","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}
