May 13, 2023 · Low Message Complexity: Maekawa’s algorithm requires only O(sqrt(N)) messages per critical section invocation, where N is the total number of processes in the system. This makes it more efficient than many other distributed mutual exclusion algorithms.

Maekawa's algorithm is an algorithm for mutual exclusion on a distributed system. The basis of this algorithm is a quorum-like approach where any one site needs only to seek permissions from a subset of other sites.

May 4, 2023 · A distributed mutual exclusion technique, such as Maekawa's algorithm, ensures mutual exclusion between running processes in a distributed system. Only one process at a time can access a shared resource thanks to the algorithm, which is based on a voting system.

Distributed mutual exclusion algorithms must deal with unpredictable message delays and incomplete knowledge of the system state. A unique token is shared among the sites. A site is allowed to enter its CS if it possesses the token. Mutual exclusion is …

Apr 15, 2024 · Below are the three approaches based on message passing to implement mutual exclusion in distributed systems: 1. Token Based Algorithm: A unique token is shared among all the sites. This approach uses sequence number to order requests for the critical section. Each requests for critical section contains a sequence number.

146 l Mamoru Maekawa number of permission messages required to obtain mutual exclusion is reduced to a half, N/2. It is also a distributed algorithm in the above sense. The approach was extended by Gifford [5] and Skeen [lo] to allow nodes to cast more than one vote.

Process: Distributed process which contains all local variables and assigned actions defined by the target algorithm. Network: Comprises the collection of processes and defines any initial relationships between them, such as neighbors in a graph or quorum members.

Maekawa’s Algorithm is quorum based approach to ensure mutual exclusion in distributed systems. As we know, In permission based algorithms like Lamport’s Algorithm, Ricart-Agrawala Algorithm etc. a site request permission from every other site but in quorum based approach, A site does not request permission from every other site but from a ...

In this paper, we present a quorum-based distributed mutual exclusion algorithm, free deadlock. Every group is organized as a logical ring of processes. A requesting process sends its request to its successor on the logical ring. When a process receives its own request after one round, it enters in the critical section. The algorithm requires.

Feb 4, 2012 · The proposed algorithm is a modification of Maekawa’s distributed mutual exclusion algorithm and signification reduction in the number of messages is being achieved by restricting the communication of any node of the quorums.
