In this paper, we design the architecture of disk-based data structures for spatial network databases (SNDB). Based on this architecture, we propose new query processing algorithms for range search and k nearest neighbors (k-NN) search, depending on the density of point of interests (POIs) ...
Multiple k Nearest Neighbor Query Processing in Spatial Network Databases This paper concerns the efficient processing of multiple k nearest neighbor queries in a road-network setting. The assumed setting covers a range of scenarios such as the one where a large population of mobile service users th...

As the Internet of Things (IoT) advances, the relevance of modeling and analyzing IoT data has expanded significantly. Because of the huge number of smart objects and the large scale of the network, classic query processing approaches aren’t always applicable, as processing large amounts of dat...
spatial databasesdistributed systemsmobile computingMoving queries over mobile objects are an important type of query in moving object database systems. In recent years, there have been quite a few works in this area. Due to the high frequency in location updates and the expensive cost of ...
