A possible approach to protect cloud systems from natural disasters corresponds to the utilization of redundant data centers located far enough apart. The time to migrate a virtual machine (VM) from a data center to another increases due to distance. As this time impacts the overall system behavior, performability evaluation considering VM migration time and different load balances is of utmost importance when considering the analysis of distributed cloud systems. This work presents performability models for evaluating distributed cloud computing systems deployed into multiple data centers considering disaster occurrence. Additionally, we present a case study which evaluates a set of scenarios with different client loads and distances between data centers.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133551012","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}

Services hosted on mobile devices consume valuable device resources such as battery power, network connectivity, and Global Positioning Systems (GPS) availability. For this research, clients consume web accessible services, provisioned from mobile devices acting as service providers. A challenge for constrained mobile devices is how the efficiency and discovery of web accessible services on mobile devices can be improved. To address this, a framework is presented that considers context information focusing on lightweight services and their discovery.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"282 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114175777","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 proposed approach can automatically manage intermediate datasets of data intensive applications, predict the cost of the applications based on the previous runs, and intelligently decide whether the intermediate results should be stored or deleted for the subsequent runs, and dynamically optimise the cost of data intensive applications in the Cloud. The experimental evaluation demonstrates the proposed data reuse mechanism can significantly reduce the overall cost and enhance the performance of data intensive applications.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115772798","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 the literature, a number of NFC M-coupon protocols were proposed in order to meet particular security requirements. However, formal security analysis is required to check the security of these protocols and whether they address their requirements. This paper mainly focuses on the formal definition of the NFC M-coupon requirements, which is the first, and most important, part of the formal analysis. The formal definitions can apply to a variety of protocols. Then, we illustrate the concept on a case study.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131686017","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 quantitative and qualitative analysis of the answers shows the necessity to revise the nature of knowledge so the classroom activities and interactive online applications enable the development of team-building skills required by employers. Also other factors such as intelligent multimedia, internet technologies, knowledge management; have a significant influence on creating innovative and inspiring collaborative learning environments where lecturers are expert designers of intellectual experiences for students who become active participants to the learning processes.","PeriodicalId":246884,"journal":{"name":"8th International Conference for Internet Technology and Secured Transactions (ICITST-2013)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121614677","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 the model, resources are organized in a virtual container and delivered to users in a holistic manner. Our work presents a business model in which additional value is created from the interaction and transactions of various virtual service actors.
