The enormous growth in the number of documents circulated over the Web increases the need for improved Web data management systems. Web data accessing and Web searching are the main processes in Web data management systems. In order to evaluate the performance of such systems, various simulation approaches must be used. In this paper, we survey the most(More)
Content delivery networks (CDNs) provide an efficient support for serving "resource-hungry" applications while minimizing the network impact of content delivery as well as shifting the traffic away from overloaded origin servers. However, their performance gain is limited since the storage space in CDN's servers is not used optimally. In order to manage(More)
Resource provisioning and resource optimization are the key issues in cloud computing. To balance the load in across virtual machine load balancing algorithms are classified into two categories i.e. static, dynamic. For homogeneous and stable environment we prefer static load balancing algorithms. For heterogeneous, dynamic environment we prefer dynamic(More)
— The exponential growth in the availability of biomedical information has posed the need to solve retrieval issues raised in huge sequence/biomedical article repositories. Biomedical article databases, like PubMed, are huge repositories of useful biological information given in natural language form and thus not easily processed by computers. Medical(More)
The enormous growth in the number of documents circulated over the Web increases the need for improved Web data management systems. In order to evaluate the performance of these systems, various simulation approaches must be used. In this paper, we study the main simulation models that have been deployed for Web data management. More specifically, we survey(More)
