Distributed clock synchronization algorithms: A survey

Distributed System is an agglomeration of sovereign computers which are linked together by a network and communicate with each other by message passing. Communication between processes in a distributed system can have unpredictable delays, processes can fail, and messages may be lost. Synchronization in distributed systems is harder than in centralized systems because the need for distributed algorithms. In this paper we see few of the algorithms which achieve clock synchronization in distributed systems.
