In recent times the role of information technology in the business enterprises has emerged with new levels of services, storage requirements, resource management and availability. As the amount of data that is available now a days is too huge for a single organization to control and manage so here putting the data on cloud can act as a savior. In this paper the advantages, various service and deployment...
With the explosive growth of cloud-based services, large-scale data centers are widely built for housing critical computing resources to gain significant economic benefits. In data centers, the cloud services are generally accomplished by multicast-based group communications. Recently, many well-known industries, such as Microsoft, Google, and IBM, adopt high-speed wireless technologies to augment...
Gaussian pyramid framework (GPF) and Laplacian pyramid framework (LPF) are the two main frameworks used for transmission and structure of spatial image and geometric data. LPF is the main approach for progressive transmission of spatial image data. This paper discusses the issues in structure, transmission and storage efficiency of spatial data in the current spatially distributed visualization system...
In view of inevitable redundancies in local data sources in heterogeneous information integration systems, a multi-copy join optimization method (MuCoJo for short) based on a genetic algorithm is proposed. MuCoJo can choose appropriate redundant copies of the tables to participate a joint query and optimizes the join order of it. By using the redundant copies, MuCoJo enlarges the search space so that...
