The distributed coordination of a group of mobile robots became a widely studied area in the last decades however the communication aided solutions became also popular research. In this paper we present the concept of cognitive swarm which enables to design faster and reliable cooperative groups by the use of cognitive infocommunication. We demonstrate the benefits of our new concept by a scenario in which a swarm of mobile robots had to guard a given area by intercepting eventual intruders. Therefore we introduce the area surveillance problem and we give both a baseline and a cognitive infocommuncation aided solution for that by the use of the basic behaviour set as fundamental. We show through simulation results that the proposed cognitive scheme can reduce the surrounding time by the factor of two leading to faster interception.
