Abstract

In this paper, we present a mechanism to fly a swarm of UAVs with the aim of establishing a wireless backbone over a pre-specified area. The backbone is aimed at connecting intermittent wireless-signal-emitting mobile ground stations (GSs), comprising rescue teams and survivors. To this end, we present a decentralized behavior-based cooperative control architecture to search for unknown GSs and relay packets from one GS to another. A delay tolerant network protocol implementation is assumed on the agents but maintained transparent to the GSs. The conditions for agent state transition are adapted to maximize a measured performance score. A novel belief exchange mechanism for cooperation is designed to utilize low bandwidth through state estimation by a Dynamic Cell Structure. Extensive simulations are performed to prove the effectiveness of the proposed solution via measured performance metrics like average latency and visit frequency.
