Evaluation of Token Based Mutual Exclusion Algorithms In Distributed Systems

This paper presents a framework for token based mutual exclusion algorithms in distributed systems.Their exists some traditional token based mutual exclusion algorithm.Some new algorithms are proposed in order to increase fault tolerance, minimize message complexity and decrease synchronization delay.In this paper, some new approaches are used, like Token ring algorithm with centralized approach, which is a betterment of the already existing token ring algorithm and overcome all the problems in the existing algorithm.A new token passing approach , which incurs 3 messages at high load, irrespective of no of node N and N message at low loads.Fairness algorithm for priority process, which has low message complexity and fairness in token algorithm.Several Token approach which allow simultaneous existence of several tokens.Hope the proposed framework provides a suitable context for technical and clear evaluation of existing and future methods.
