It has also gained a lot of importance in the academic community and industry. This is particularly due to the high level of security that it offers with relatively small size of the keys, in addition to its ability to the construction of original protocols which are characterized by high efficiency. Moreover, it is a technique of great interest for hardware and software implementation. Pairing-friendly curves are important for speeding up the arithmetic calculation of pairing on elliptic curves such as the Barreto-Naehrig (BN) curves that arguably constitute one of the most versatile families. In this paper, the proposed architecture is designed for field programmable gate array (FPGA) platforms. We present implementation results of the Miller's algorithm of the optimal ate pairing targeting the 128-bit security level using such a curve BN defined over a 256-bit prime field. And we present also a fast formulas for BN elliptic-curve addition and doubling. Our architecture is able to compute the Miller's algorithm in just 638337 of clock cycles.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125050723","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}

We take images from two cameras and match points to determine disparity, and therefore depth. The optical flow method is used to estimate motion field in a video scene.

SCTP is an innovative transport layer protocol, which is reliable and provides services such as multihoming and multistreaming. CMT extension allows simultaneous utilization of multipaths for reaching the higher data transmission rate between two hosts, which is beneficial for the emerging multi-interface devices. The literature on CMT-SCTP optimization shows that, there are several simulation tools used by the researchers for performance evaluation, to validate propositions and to experiment the further extensions of SCTP/CMT-SCTP. Indeed, such tools are convenient and can quickly verify the proposal results. We establish a real lab Internet setup first and then design a number of test scenarios for CMT-SCTP. To verify our implementation the simulations needs to be performed on the test scenarios to set a reference output prior to the lab setup experiments. The experiment results from the successful implementation of CMT-SCTP on the real lab setup agrees to the reference output reasonably.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116271718","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 paper, therefore, we propose a new methodology to dynamically extract real-time data from various internal and external data sources passively, i.e. after receiving the decision making query. We propose a methodology to store and exchange intensional data (in AXML format) to activate and automate the integration of real-time data and updates. AXML database will be proposed as a structural metadata to integrate data from external data sources and manipulate external models for accurate decision making. Our approach should be seen as a complementary, not a replacement, for the data warehousing approach.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127490669","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}

Generally, WSN suffer from finite energy resources (limited lifetime), and limited network coverage (due to transmission range). The most consistent works on energy consumption and radio transmission modeling for WSN, are not taking into account realistic constraints. However, radio propagation is affected by a lot of kinds of obstacles (walls, windows, doors...) with different effects on the radio propagations. For this, a proper and more realistic radio propagation model is essential to optimize energy consumption and ensure network reliability (best network coverage). In this paper, we investigate the impact of the radio propagation modeling on the network energy consumption with and without obstacles (walls) consideration. This work leads to evaluate a proper radio behavior model with the objective to use it in an optimization process.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134599642","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}

It allows users to interact with computers. Such computers can exist in different forms such as laptops, tablets, a pair of glasses (wearable computers) and clothes or wearable fabrics that are sensor-embedded. It is essential to explore the different applications of pervasive computing to learning in classroom environments, in order to foster learning and promote well-being among students. One of the problems currently confronting some developing countries is a lack of adequate facilities to support proper learning in classroom environments. This has had a negative impact on the performance of students at various levels of educational learning. In this paper, a review of current trends, future trends and applications of pervasive computing was explored, particularly with respect to classroom learning environments, and a generic model of pervasive computing technology was proposed for adoption in classroom learning environments of developing countries, particularly the Nigerian tertiary institution's classroom learning environment.","PeriodicalId":270622,"journal":{"name":"2014 Global Summit on Computer & Information Technology (GSCIT)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125198425","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}
