%T A Fault Tolerant Token-based Algorithm for Group Mutual Exclusion in Distributed Systems
%V 14
%X The group mutual exclusion (GME) problem is a
variant of the mutual exclusion problem. In the present paper a
token-based group mutual exclusion algorithm, capable of handling
transient faults, is proposed. The algorithm uses the concept of
dynamic request sets. A time out mechanism is used to detect the
token loss; also, a distributed scheme is used to regenerate the token.
The worst case message complexity of the algorithm is n+1. The
maximum concurrency and forum switch complexity of the
algorithm are n and min (n, m) respectively, where n is the number of
processes and m is the number of groups. The algorithm also satisfies
another desirable property called smooth admission. The scheme can
also be adapted to handle the extended group mutual exclusion
