This paper presents a novel approach to the problem of discovering and ranking the characteristics of the data sources and query processing sites in a distributed database system. We model the network as a graph with nodes representing data sources and query processing sites, some of which might be replicated.We introduce a heuristic technique inspired in Ant Colony Theory to dynamically discover,assess...
The emergence of location-aware services calls for new efficient real-time queries processing algorithms. In this paper, we focus specifically on real-time processing of range-monitoring queries. Ying Cai et al. introduced a technique called monitoring query management (MQM) for efficient real-time processing of range-monitoring queries in heterogeneous mobile databases. The technique involves allowing...
