A Variable-Length Quorum Generation Algorithm for Distributed Mutual Exclusion

Based on the advantages and disadvantages of LUK's and LI's algorithms, a symmetric distributed mutual exclusion quorum generation algorithm with variable-length has been presented. Through introducing the concepts of laxity and average permission repeat times, the time complexity of this quorum generation algorithm became to O(N/2) and the quorum length became N
^1/2
+laxity.
