11. CONCLUSION The main idea behind two process is decentralization . The communication delay is reduced at the cost of increased intelligence at the local level. If collaborative intelligence exceeds combinatorial complexity then there is no need of communication between controller and requirements of central process. Thus the performance matches to that of the centralized MIMO system.
