DTTC: Delay-Tolerant Trajectory Compression for Object Tracking Sensor Networks
Taking advantage of the delay tolerance for objects tracking sensor networks, we propose delay-tolerant trajectory compression (DTTC) technique, an ef´Čücient and accurate algorit...

Compressing Spatio-temporal Trajectories
Trajectory data is becoming increasingly available and the size of the trajectories is getting larger. In this paper we study the problem of compressing spatio-temporal trajectorie...
