ESTA

Designed an Efficient Spatial-Temporal Range Aggregation Query Processing (ESTA) Algorithm for UAV networks. Leveraging a constructed Topology Change Graph (TCG), the algorithm employs an efficient shortest path method to determine user query delay. ESTA then transforms the aggregation of query results into a recursive set cover problem, constructing a Spatial-Temporal Aggregation Tree (STAT) to identify an optimal in-network aggregation routing path for query results while maintaining user query delay requirements.
