No common or global memory is shared by the nodes for internode communication; instead this is done by exchanging messages. The algorithm requires at most 3√n messages per mutual exclusion invocation. Under heavy demand the message requirement reduces to √n....
In this article, we propose a coterie-based mutual exclusion algorithm for distributed systems allowing process failures at arbitrary time. The proposed algorithm is an extension of Maekawa's algorithm, which is a representative conventional method for distributed mutual exclusion based on coterie. The...
Dijkstra's mutual exclusion algorithm. 互斥锁(mutual exclusion)是一个很经典的并行计算问题. 我们今天来看一下知名计算机科学家dijkstra在1965年提出的一个算法 https://dl.acm.org/doi/pdf/10.1145/365559.365617 以及对其进行一系列证明. 通过对这个算法进行学习我们也将对怎么定义分布式系统有一个大方向上的想法....
Distributed mutual exclusion is a fundamental problem in distributed systems since resources are shared and exclusive access to these resources are needed as in a single-node computer system. Algorithms for this purpose may be broadly classified as permission-based or token-based algorithms. A process...
Proposed Distributed Mutual Exclusion Algorithms A fair decentralized mutual exclusion algorithm for distributed systems is proposed in which processes communicate by asynchronous message passing. The algorithm requires between (N-1) and 2(N-1) messages per critical section access, where N is the number...

, Fribourg, and Picaronny generalized the algorithm to the fully asynchronous setting [22], but at the cost of a bound that depends on the number of processors. More recent work has also looked at randomized mutual exclusion for a single lock and without helping [18,19]. This work has ...
Mutual Exclusion Algorithm Single resource that can be held by at most one process at a time. Each site issues a request to acquire permission to access the resource. Use Lamport’s clock to define the order in which the resource will be accessed. ...
The concept of k-coterie is introduced and a distributed k-mutual exclusion algorithm is proposed using it. A k-coterie is a natural extension of a coterie. The message complexity of the algorithm is O(c) when conflicts with other processes in capturing a quorum do not occur, where c is...
Distributed AlgorithmMutual exclusionThe serial model for self-stabilizing distributed algorithms assumes that the reading of the states of the neighbors and the updating of its own state are grouped together into one atomic operation (indivisible execution step) the model also assumes that each node ...
