The essence of IoTs is to connect all the things including the devices embedded RFID, sensors, etc. together, to help people utilizing the information from the things to improve their life. The things are always located at different places at different times, and the information of the thing may have different access right at different location during different time. Therefore, the access control mechanism in IoTs should consider location and temporary constraints in order to enhance the security of an application. In this paper, we propose a model that combines location and time with security level to control access to the information within the sensing layer of the IoTs. This model is called Location-Temporal Access Control Model(LTAC). The main principle of LTAC is its use of a lattice approach to decrease the size of policy bases. We show that how the different components in the model are related with location and how this location information can be used to determine whether a subject has access to a given object.</p></div>","PeriodicalId":100008,"journal":{"name":"AASRI Procedia","volume":"5 ","pages":"Pages 15-20"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aasri.2013.10.053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89009668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We can observe that often a huge amount of data is exchanged by medium/low bandwidth networks or yet, they need to be stored on devices with limited space of memory. In this context, the present paper shows the use of the Fractal method for image compression. It is a lossy method known by providing higher indexes of file reduction through a highly time consuming phase. In this way, we developed a model of parallel application for exploiting the power of multiprocessor architectures in order to get the Fractal method advantages in a feasible time. The evaluation was done with different-sized images as well as by using two types of machines, one with two and another with four cores. The results demonstrated that both the speedup and efficiency are highly dependent of the number of cores. They emphasized that a large number of threads does not always represent a better performance.</p></div>","PeriodicalId":100008,"journal":{"name":"AASRI Procedia","volume":"5 ","pages":"Pages 140-146"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aasri.2013.10.070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73156484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These information resources with a variety of different languages are distributed in Web pages and the databases. The scheduling of multilingual information resources becomes complex, as multilingual information resources are heterogeneous and uneven in cloud computing. The need arises in scheduling of multilingual information resources in cloud computing for new mechanisms. This paper presents a four-tier architecture for multilingual information resources scheduling in cloud computing. It includes user accessing tier, technology supporting tier, resource scheduling tier and resources tier. We propose a three- layer scheduling model for multilingual information resources in cloud computing. The model includes some home managers, some local scheduling agents and a global scheduling agent. The model not only shows the autonomy of private cloud resources and is convenient for user to submit and supervise tasks, but also lightens the pressure of the global scheduling agent. The example shows that the proposed scheduling model could improve the performance of the scheduling of multilingual information resources in cloud computing.</p></div>","PeriodicalId":100008,"journal":{"name":"AASRI Procedia","volume":"5 ","pages":"Pages 268-273"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aasri.2013.10.088","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78415329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
