Mutual exclusion (Mutex) is a major coordination problem in distributed systems. To handle Mutex, the corresponding solutions are mainly classified into permission-based, token-based and quorum-based protocols. Mobile Ad-hoc Networks referred as MANETs introduce new obstacles for designing algorithms that help in solving distributed mutual exclusion problem. To our knowledge, few algorithms have been...
The group mutual exclusion problem is a simplification of mutual exclusion problem such that a set of processes in the similar group can enter a critical section all together. To handle group mutual exclusion, the interrelated solutions are chiefly classified into quorum-based, token-based as well as permission-based protocols. The proposed algorithm is based on tokens; a process that grasps a token...
