Abstract

Monitoring dense areas, where the density of moving ob- jects is higher than the given threshold, has many applica- tions like traffic control, bandwidth management, and col- lision probability evaluation. Although many studies have been done on density queries for moving objects in highly dynamic scenarios, they all focused on how to answer snap- shot density queries. In this paper, we focus on continuously monitoring dense regions for moving objects. Based on the notion of safe interval, we propose effective algorithms to evaluate and keep track of dense regions. Experimental re- sults show that our method can achieve high efficiency when monitoring dense regions for moving objects.
