Optimizing Aggregate Query Processing in Cloud Data Warehousesof relational data in a star-schema. Existing aggregate query processing algorithms focus on optimizing various query operations but give less importance to communication cost overhead (Two-phase algorithm). However, in cloud architectures, the communication cost overhead is an important factor in q

A General Nash Equilibrium Semantic Cache Algorithm in a Sensor Grid Databaseplication development. We propose an adaptation of a well-known cache-based optimization and cache replacement policy to this context. Since the data are distributed and the sensor nodes are mobile, the cost model is more complicated than in traditional query optimization, because it should account

Towards Privacy for MapReduce on Hybrid Clouds Using Information Dispersal Algorithmrastructures, such as public clouds and desktop grid, while using a trusted infrastructure, such as private cloud, to ensure that no outsider could get the ’entire’ information. Our idea is to break data into meaningless chunks and spread them on a combination of public and private clouds so that th
