Abstract
Drones are broadening their scope into various applications such as agriculture, package delivery, broadcast, leisure, and rescue, among others. However, drones must overcome some technical issues to become widely usable. One such issue is resilience in communication. Current drones are normally remote-controlled. This makes it hard to successfully complete missions without continuous communication. When drones experience communication failure due to interference, non-line-of-sight, or jamming, one possible solution is spatial retreat to evacuate them from the communication failure area. Previous spatial retreat schemes only move the drones in random directions. In doing so, the accuracy and efficiency of the moving distance is not adequate. In this paper, we propose a novel retreat technique that can enable resilient networking. Our approach is called cooperative spatial retreat (CSR). We have found it to significantly outperform existing schemes by exploiting telemetry communication modules. ⓒ 2017 DGIST
