U.S. - Greece Cooperative Research: Dynamic Data Allocation in Distributed Systems

9812325沃尔夫森这个为期三年的奖项提供了与Michalis Vazirgiannis在希腊雅典经济和商业大学的分布式系统中的动态数据分配的合作研究。 该研究的三个目标是建立分布式系统中的自适应复制的原则;开发，实现和分析对象的自适应复制系统;并建立一个模拟试验床，在该试验床中，用户定义网络，并选择复制算法，成本模型和访问模式。 该系统将使各种自适应和静态算法之间的比较。 该项目将Wolfson在自适应复制方面的经验与Vazirgiannis在时空数据库方面的专业知识相结合，这对模拟测试平台的开发至关重要。 预计该项目将有助于利用互联网和万维网发展分布式、完全互联的信息环境。

9812325WolfsonThis three-year award provides for collaborative research with Michalis Vazirgiannis at the Athens University of Economics and Business in Greece on dynamic data allocation in distributed systems. The three objectives of the research are to establish principles of adaptive replication in distributed systems; to develop, implement and analyze a system for adaptive replication of objects; and to build a simulation testbed in which the user defines the network and selects a replication algorithm, a cost model, and an access pattern. The system will enable comparison among various adaptive and static algorithms. The project combines Wolfson's experience in adaptive replication with Vazirgiannis' expertise in spatio-temporal databases, which is critical for the development of the simulation testbed. The project is expected to contribute to the development of the distributed, wholly interconnected information environment using the Internet and the World Wide Web.
