The basic idea of ESTA

Designed an efficient spatial-temporal range aggregation query processing (ESTA) algorithm for UAV networks. Based on the constructed topology change graph (TCG), an efficient shortest path algorithm is proposed to obtain the user query delay. Then ESTA transforms the aggregation processing of query results into recursively solving the set cover problem, thus constructing a spatial-temporal aggregation tree (STAT) to find an efficient in-network aggregation routing path for query results without sacrificing the user query delay.
