Quorum Based Distributed Mutual Exclusion Algorithms in Mobile Networks
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. Quorum based algorithms is one such class of algorithms where the requesting site asks permission from a set of smaller number of participating sites called a quorum. Quorums help reduce the message complexity in mobile systems.
