PERFORMANCE ANALYSIS OF QUORUM BASED ALGORITHMS IN CELLULAR NETWORKS

Abstract

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 Mutual Exclusion assigns channels to various cells and increases bandwidth utilization. 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. Performance analysis of quorum based algorithms is done using message complexity, synchronization delay, response time system throughput as the metrics.
