A MUTUALLY EXCLUSIVE APPROACH FOR MANAGING MOVABLE DATA OBJECTS

Abstract

An operating system is a program that manages the resources of a computer system and provides users with a friendly interface to the system. A distributed system extends the concepts of the resource management and user friendly interface for shared memory computers a step further, encompassing a distributed computing systems consisting of several autonomous computers connected by a communication network. The problem of mutual exclusion frequently arises in distributed systems, whenever concurrent access to shared resources by several nodes is involved. In the mutual exclusion problem, concurrent access to a shared resource by several uncoordinated user-requests is serialized to secure the integrity of the shared resources. In an environment where movable data objects are required, it is necessary to develop a method to manage the location of these objects. Here an algorithm is proposed that manages the location of multiple movable resources in distributed system whose sites commu...
