Aggregate Nearest Neighbor Queries In Road Networks

Aggregate nearest neighbor queries return the object that minimizes an aggregate distance function with respect to a set of query points. Consider, for example, several users at specific locations (query points) that want to find the restaurant (data point), which leads to the minimum sum of distances that they have to travel in order to meet.

Jul 06, 2005 Abstract. Many applications using sensing data require the fast retrieval of aggregated information in sensor networks. In this paper, distributed spatial index structure in sensor networks for time-efficient aggregation query processing is proposed.

Improving Search In Peertopeer Networks

network, nodes spend processing resources (i.e., cycles) to forward the query, process it, etc, and bandwidth to send and receive messages. The main cost of queries are there-fore bandwidth and processing. Since the cost of a query is not incurred at any single node in the network, it makes sense to discuss costs in aggregate (i.e., overall the ...

Evaluation Of Topk Olap Queries Using Aggregate Rtrees

In this paper, we study the integration of the top- operator with the aggregate query processing module. For this, we make use of spatial indexes, augmented with aggregate information, like the aggregate R-tree. We device a branch-and-bound algorithm that accesses a minimal number of tree nodes in order to compute the top- groups.
