【摘要】

Many animal groups organize into flocking formations where individuals obtain a high degree of velocity alignment with each other. Such collective states are mobile and cohesive, providing collective benefits from energy saving to predation avoidance. The self-organization of group members into a flock requires information, regarding directions of individual velocities, sharing across the whole group.
In collective social groups, interactions between individuals can achieve information sharing by forming swarm signaling networks (SSNs) where the connections are determined by the perceptual constraints and attention capacities. When modeling individual behaviors, perception is the input which contains information about the surroundings. The perception has its sensory basis which constrains the available sources and type of information. Meanwhile, whether perceivable information is responded to form real connections in SSNs depends on the attention, which also obtains limited capacities.
In our work, we show how flocking behavioral rules obtain different group stability regarding individual capacity of attention under realistic perception. The results not only indicate a minimal attention capacity for stable flocking formation, but also provide evidence connecting perception models to geometrical models.
