The problem of Distributed Mutual Exclusion (DME) has been studied significantly over the years. The proposed protocols, in the existing literature, consider the various parameters, viz., liveness, fairness, message complexity and safety for optimization. The problem of DME can be handled using two approaches, namely, token-based and permission-based. In the paper, the authors propose an optimized Permission-based algorithm in which the total number of messages has been considerably reduced with the help of a new message "Hold". In parallel, they have also reduced the number of sites to which a node has to send "Hold" message by applying timestamp priority.
