Self-organization has become an intensely researched area, being considered the new control system science. Different self-organizing algorithms (bio and non-bio inspired) have been developed by scientist worldwide with general applicability in autonomous systems, multi-robot systems, autonomic networking, sensor and actor networks and mobile ad hoc networks. This paper presents a comparative analysis of basic architectures for multi-robot systems from the point of view of self-organization capabilities. We identify requirements for implementing efficiently self-organization mechanisms with high applicability in multi-robot systems.
