This is done through a cooperative algorithm that allows individual nodes to measure the trust of the TOR nodes they communicate with. The paper measures the performance of this algorithm and shows that the algorithm can accurately identify several kinds of malicious nodes in the TOR network. This paper will focus on the following security issues: the problem of self reported bandwidth and uptime that can lead to low resource attack, geographical location and Denial of service (DoS) attack and how to aggregate all these criteria in one value that indicate whether or not the onion router is malicious. The aggregation is performed using two different techniques, each of which uses the exact same aggregation methods except for geographical location. The first method, which excludes entire geographical locations, produced slightly worse results than the second method, which assigned a scale between 0 and 0.99 for each geographical location to signify its trust","PeriodicalId":162170,"journal":{"name":"2014 24th International Conference on Computer Theory and Applications (ICCTA)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127688913","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}

Work hours, number of day and night shifts that should be worked by each nurse, the number of consecutive day and night shifts assigned, vacation periods and weekend off requests are important factor during building the scheduling. This paper proposes a Quality Based Nurse Scheduling model (QBNS). It’s a new perspective to solve the nurse scheduling problem for nurse’s duty roster which is one of the most important components in healthcare who provides services to the community round the clock. Nurse scheduling is an orchestrating dynamic process which needs coordination and interaction besides the scheduling shifting methodologies and algorithms. This scheduling has many features. It improves the quality of nurses output and working as teamwork. It also proposes scheduling based on the daily outcome for every nurse through a reliable evaluation technique which automatically distributed the nurses to the shifts in pairs. In addition to previous features it maximizes nurses preferences, minimizes unfairness assignments and finding a balanced/fair schedule.","PeriodicalId":162170,"journal":{"name":"2014 24th International Conference on Computer Theory and Applications (ICCTA)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134451139","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 we propose and develop a multi- agent-based university advising system for advising undergraduate students instead of the traditional advising method through departments’ advisors. This system aims at assisting undergraduate students of the Information System (IS) major at the Arab Academy for Science, Technology and Maritime Transport (AAST) to select the suitable courses during their undergraduate program. The proposed system enables students to select suitable courses for each semester without the need to consult advisors. Moreover, it takes into account course prerequisites and priorities. Java language, JADE platform and oracle 11g database are used to implement the system. As anticipated, the findings revealed that most of the undergraduate students who tested the system were very satisfied, as the results issued by the proposed system were found to be compatible to a large extent with the views of academic advisors.","PeriodicalId":162170,"journal":{"name":"2014 24th International Conference on Computer Theory and Applications (ICCTA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116241287","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}

Such distributed systems rely on data fragmentation and distributed storage of data over multiple peers. Files are usually partitioned into fixed-size blocks that are themselves partitioned into fragments. In such systems, some peers (clients) exploit the power of parallelism to download blocks/fragments of data stored in a distributed way over some other peers (servers). This idea is deployed even over a network of servers (mirrors and cache) to reduce download time. Determining response times in parallel downloading with capacity constraints on both the client downloads and server uploads is then an important measure of the quality of the service given by these systems. This download time depends on the throughput of the different connections created to obtain the fragments of the given file. This paper enriches the literature with a simple stochastic model of the download process in such large and complex systems. In particular, it characterizes the response time performance metric and assesses its expectation through Markovian model and validates the study through the packet level Network Simulator NS-2. The relative error between the numerical results of the proposed model and the result of the simulation is reported. The comparison shows that the Model characterizes with high accuracy the response time under realistic assumptions.","PeriodicalId":162170,"journal":{"name":"2014 24th International Conference on Computer Theory and Applications (ICCTA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117005459","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}
