Evaluation of an algorithm in terms of processing speed (run time) and space (data structures) is therefore a critical step in ascertaining suitability of an algorithm for a particular application. Major limitation in physical processing speed is principally associated with the complex computations required to provide solutions to large size problems (Jaja, 1992). With an increase in massive parallelism of processors, the overall processor operational speed has drastically improved especially in image processing. The best choice of an algorithm on a particular processor and for a particular task is based on the understanding of the performance of the algorithm and hardware at hand. In this paper, we address this problem by providing a means to know the characteristics of a given algorithm by evaluating its performance. Two segmentation based SSAR algorithms, namely the 1-D and 2-D data segmentation are evaluated and algorithm performance indexes drawn. In both cases, image data was split into segments and parallel processed by individual asynchronous processors. Based on the relationship between the non-overlapping data segment size and execution time, the performance index of an algorithm was determined.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130783963","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}

The technology is far better than its other contending systems such as Barcodes and magnetic tapes as it provides optimal communication link with non line of sight capability. Several researchers have proposed various ultralightweight RFID authentication protocols to provide cost effective security solutions. However, the proper hardware implementation of these ultralightweight authentication protocols has been neglected long which develops a chaos of their practical feasibility. In this paper, we have addressed this problem and proposed generic hardware architecture for EPC-C1G2 tags. We have also simulated four ultralightweight authentication protocols (SASI, LMAP, David-Prasad and RAPP) using ModelSim PE and synthesized using Xilinx Design Suite 14.5. Algorithm has been successfully implemented in hardware using Spartan 6 (Low Power) and Vertex 7 Field Programmable Gate Array (FPGA). We believe that the proposed architecture and simulated results will act as the stepping stone for the future implementation of these low cost RFID tags for ASIC.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132088788","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}

Channel switching is inherently necessary to make unlicensed and licensed users to appropriate propagation in the channel. All through the progression, communication characteristics such as bottleneck bandwidth and Round-trip time (RTT) have to be modified. However this change has to adaptively update by TCP in its congestion window (CWND) to make an efficient use of the available resources. TCP CRAHN is well-known mechanism which generates spectrum alertness by retrieving explicit feedback from relay and destination nodes. In this paper we proposed TCP CR-MANET and it is evaluated with respect to bottleneck bandwidth and RTT varying characteristics. This protocol updates its CWND based upon the available buffer space of the relay node. TCP CRMANET system is implemented in NS2 simulator and analyzed with various characteristics of the network. Experimentally, it has been proved that our proposed TCP CR-MANET provides better throughput with respect to TCP CRAHN.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121139924","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}

End-to-end connectivity is established by tunneling. OpenVPN and OpenSSH are cross-platform, secure, highly configurable VPN solutions. The performance comparison however between OpenVPN and OpenSSH VPN has not yet been undertaken. This paper focuses on such comparison and evaluates the efficiency of these VPNs over Wide Area Network (WAN) connections. The same conditions are maintained for a fair comparison. To the best knowledge of the authors, this is the first reported test results of these two commonly used VPN technologies. Three parameters, namely speed, latency and jitter are evaluated. Using a real life scenario with deployment over the Linux Operating System, a comprehensive in-depth comparative analysis of the VPN mechanisms is provided. Results of the analysis between OpenSSH and OpenVPN show that OpenSSH utilizes better the link and significantly improves transfer times.","PeriodicalId":300052,"journal":{"name":"2015 International Conference on Computing, Communication and Security (ICCCS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127712479","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}
