The addition of reinforcement learning (RL) based network management agents can improve Quality of Service (QoS) by reconfiguring the network layer protocol parameters in response to observed network performance conditions. This paper presents a closed-loop approach to tuning the parameters of the protocol of network layer based on current and previous network state observation for user and channel interference, specifically by modifying some parameters of Ad-Hoc On-Demand Distance Vector (AODV) routing protocol for Cognitive Radio Ad-Hoc Network (CRAHN) environment. In this work, we provide a self-contained learning method based on machine-learning techniques that have been or can be used for developing cognitive routing protocols. Generally, the developed mathematical model based on the one RL technique to handle the route decision in channel switching and user mobility situation so that the overall end-to-end delay can be minimized and the overall throughput of the network can be maximized according to the application requirement in CRAHN environment. Here is the proposed self-configuration method based on RL technique can improve the performance of the original AODV protocol, reducing protocol overhead and end-to-end delay for CRAHN while increasing the packet delivery ratio depending upon the traffic model. Simulation results are shown using NS-2 which shows the proposed model performance is much better than the previous AODV protocol.","PeriodicalId":407600,"journal":{"name":"2015 International Symposium on Mathematical Sciences and Computing Research (iSMSC)","volume":"33 7-8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116471261","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 problem involves ten data sets with different number of customers to be served and different number of disposal facilities available. A heuristic algorithm, namely Different Initial Customer from a previous study is used to solve the problem by constructing vehicles routes for the drivers with two main objectives; to minimize the total distance travelled and to minimize the total number of vehicles needed to collect the waste. The results compared well with other solutions in the literature. However, the solutions did not consider the balance of the vehicle routes constructed. Thus in this paper, we evaluate the quality of the solutions in terms of the total distance travelled assigned to each driver. First, we identify the distance travelled of each driver using Different Initial Customer procedure for the data sets. Then, we calculate standard deviation (SD) of each solution in order to analyze the drivers' workload. Low SD value indicates small workload difference between drivers. Finally, the SD value is compared and the analysis shows that the solution with the minimum SD may increase the total distance travelled as well as the number of drivers needed to complete the collection.","PeriodicalId":407600,"journal":{"name":"2015 International Symposium on Mathematical Sciences and Computing Research (iSMSC)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114693099","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}

Besides the overall rankings, the universities are also ranked by subjects serving as comprehensive guide to discover the specialist strengths of universities worldwide by highlighting top 200 universities for a range of 30 individual popular subjects. Data for this ranking purpose consist four variables namely the academic reputation, employer reputation, citation per paper and H-index citations. In this ranking, universities are ranked according to their overall score calculated from linear combination of the aforementioned variables and their respective weightings. As the existing ranking technique based on overall score appears to be simple and since the rankings data are of multivariate nature, therefore it is possible to use multivariate statistical technique like cluster analysis. Agglomerative hierarchical cluster analysis of top 200 QS ranked universities by Mathematics subject area 2014 has been performed to obtain natural clustering of the universities in an objective manner. The agreement between cluster analysis and existing QS rankings is verified and it is suggested that the distance between universities can be used as an alternative measure to rank universities. Cluster analysis applied on the same variables would serve as an alternative way to rank universities and to look at the rankings in a different perspective.","PeriodicalId":407600,"journal":{"name":"2015 International Symposium on Mathematical Sciences and Computing Research (iSMSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129882668","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 literatures show lack of study on e-SQ in Malaysian universities. This gap should be considered because universities suffer from a continuous rivalry to attract students not only to achieve high income, but also to improve the universities ranking. This research aims to fill this gap by defining the significant dimensions for measuring e-service quality in higher education in Malaysia to help universities to enhance their e-services to exceed their competitors and achieve high tuition-based returns. Nine dimensions are proposed for evaluating e-services in Malaysian universities. These dimensions are selected from the common scales of e-service quality as they can affect the students' perceives and expectations towards the services. Moreover, the selected dimensions are covered all the aspects of e-service quality in higher education in terms of their variation and their contents. A pilot study based on structured questionnaire is conducted with the students of five universities to collect the data necessary for the research. EFA analysis is conducted by using SPSS software package to analyze the data and come out with the new e-SQ dimensions. The results revealed that six dimensions are of great importance in evaluating the e-services provided by the Malaysian universities.","PeriodicalId":407600,"journal":{"name":"2015 International Symposium on Mathematical Sciences and Computing Research (iSMSC)","volume":"315 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133785080","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}
