Collective decision making using natural self-organization in distributed systems

Distributed systems without centralized elements need a distributed mechanism that allows accomplishing the control and synchronization tasks. This problem is especially relevant in nanoand biosystems that do not possess complex computational devices. However the collective coordination and decision making may be performed using the available in these systems natural dynamical processes based on chemical, optical, electromagnetic or quantum effects. Utilizing these dynamical processes, the transfered information within distributed system is firstly efficiently coded, secondly, does not contain the global information about the whole system. This guarantees security and privacy being also very important in other fields, e.g. in e-commerce.
