Collision-Free Multi-Agent Coverage Control for Non-Cooperating Swarms: Preliminary Results

The main contribution of this paper is a methodology for multiple non-cooperating swarms of unmanned aerial vehicles to independently cover a common area. In contrast to previous research on coverage control involving more than one swarm, this paper does not assume cooperation between distinct swarms but considers them as independent units following their own objectives. Using Voronoi tessellation, collision-free motion of agents within the same swarm has been proven before. However, as is shown in Example 1 of this paper, in the case of multiple swarms with inter-swarm but without intra-swarm collaboration, these guarantees do not hold. We address this issue by proposing an algorithm to achieve maximum coverage with multiple swarms while avoiding collisions between agents. More specifically, the Optimal Reciprocal Collision Avoidance method used for safe navigation in multi-agent scenarios is adapted to suit the needs of Voronoi-based coverage control with more than one swarm. The functionality of the proposed technique is validated through Monte Carlo simulations.
