After analyzing the fundamental disadvantages of grid computing, we propose the concept of spatial cloud computing, which consists of domain spatial data set, spatial cloud service, and spatial cloud. The dynamic structure of spatial cloud computing uses the lifecycle of spatial cloud lifecycle as a clue. We then discuss solutions for global virtualization,(More)
CAN is a famous structured peer-to-peer network based on ddimensional torus topology with constant degree and logarithmical diameter, but suffers from poor scalability when N>>2, N is the number of peers. To address this issue, we proposes a novel scalable structured peer-to-peer overlay network, CDACAN that embeds the one-dimensional discrete distance(More)
Based on quotient space granular analysis, geohazards prognosis problem is defined as a triple, thereby prognosis identity description is accomplished. Quotient space granulation theory provides many methods which can realize from "Abstract Prognosis" to " Careful Prognosis", such as universe division, rough set quantization(More)
