Based on obtained characteristics, we design a new block I/O scheduler. Different from mechanical hard disk device (HDD), SSDs have many widely cognitive features, such as none-mechanical, inherent parallelism, high read and write speeds and so on. Considering the current system schedulers are optimized for HDD, we suppose these schedulers may be not optimal for SSD. We manage to modify the essential parts of system schedulers and test them under different workloads, then summarize the characteristics for improving performance like sorting order of requests, read-write interference and parallelism. We implement a new scheduler called Layer_Read which has the different organizations according to the access pattern on a Linux 2.6.34 kernel. The scheduler divides read requests into different sub-layers in accordance with their starting sector numbers, and dispatches requests in a round-robin way among the sub-layers in order to utilize inherent parallelism. Besides that, the scheduler continuously dispatches multiple read or write requests which can reduce the read-write interference. Through the experiment validated, the scheduler has some performance improvement when compared with other system schedulers.","PeriodicalId":422906,"journal":{"name":"2014 IEEE Computers, Communications and IT Applications Conference","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129482367","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}

Due to increasing use of commercial/open source technology and communication protocols, there are growing concerns about the associated security threats. SCADA networks are usually employed in critical infrastructure, therefore, not much technical data of the actual systems is accessible to the research community. Most of the researchers simulate the SCADA functioning through development of testbed. Such projects are usually expensive and requiring financial sponsorship. In this paper we present a simple, inexpensive and flexible approach to develop a SCADA testbed utilizing TrueTime, a MATLAB/ Simulink based tool. The paper describes TrueTime simulation blocks, our control system, simulation of Denial of Service (DoS) attack and its effects. The main aim was to assess the effectiveness and suitability of TrueTime for the intended use in the development of a larger scale SCADA testbed. The results shown reflect that TrueTime can be effectively used for the purpose of SCADA network simulations and collection of necessary data for security analysis.","PeriodicalId":422906,"journal":{"name":"2014 IEEE Computers, Communications and IT Applications Conference","volume":"352 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134553852","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, they are deficient in two folds: firstly, packet loss is not considered in the truncated rate-distortion model; secondly the reference of original video sequence is unavoidable. To overcome the above shortcomings, this paper firstly introduces a low complexity error propagation distortion model, in which error drift distortion due to rate truncation and packet loss can both be analyzed in the absence of the original sequence. Based on this model, an optimized bit extraction algorithm is proposed for the transmission of H.264/SVC MGS stream over bandwidth limited error-prone channels. Extensive simulation results show that, the error drift distortion of both base layer and enhancement layer can be accurately predicted based on the introduced error propagation distortion model. In addition, compared with the benchmark bit extraction algorithms provided by JSVM, our proposed algorithm can not only provide a higher reconstructed quality of truncated MGS video stream under various rate constraints and channel conditions, but as well achieve the promising performance with a much lower time complexity.","PeriodicalId":422906,"journal":{"name":"2014 IEEE Computers, Communications and IT Applications Conference","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123136950","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}
