The assigned frequency spectrum to the wireless mobile systems has become a scarce resource as the number of mobile users has increased tremendously. So there is a need of using the allotted bandwidth efficiently. Distributed RME assigns channels to various cells and increases bandwidth utilization and at the same time reduces co-channel interference. Various algorithms exist which help in attaining mutual exclusion.
