In this paper, we propose the distributed bees algorithm (DBA) for task allocation in a swarm of robots. proposed scenario, consists assigning robots to found targets 2-D arena. The expected distribution is obtained from targets' qualities that are represented as scalar values. Decision-making mechanism and autonomously choose their assignments taking into account distances. We tested scalability DBA terms number targets. For that, experiments were performed simulator various sets...
