Trajectory Design for Effective and Secure Communication in UAV-WSN Systems

Nowadays, unmanned aerial vehicles (UAVs) and wireless sensor networks (WSNs) are often integrated in collaborative systems for data collection. In this paper, a specific UAV trajectory design for effective and secure data collection from ground sensors is presented. Depending of the amount of data and radio communication characteristics, two types of trajectory are designed: segment tracking and loitering in a circle around the WSN cluster head.
