In a distributed system of N sites an efficient solution to the critical section problem is proposed to allow multiple simultaneous entries to the Critical Section. The proposed solution is token-based, deadlock-free and free from starvation. In all cases except during the book keeping cycle of...
The synchronization mechanism ensures that only one thread can be in the critical section at any given time, eliminating the possibility of data corruption or concurrent modifications. Deadlocks and Starvation While using locks to protect the critical section solves the problem of concurrent access, it...
