A Truant Failure Detection Algorithm for Mult i-Policy Distributed Systems

In recent autonomous decentralized systems, every node might not execute the same algorithm because it might have i ts own local policy and follow that pol-icy rather than the common principle. In this paper, we model these systems as a multi-policy distributed system. W e introduce a new type of failure, a truant failure, on multi-policy distributed systems, which i s considered to be the simplest local policy. A truant failure node does nothing fo r the other nodes ’ requests selected by i ts local policy. This paper shows a condi-tion to be able to detect a truant failure and presents a distributed truant failure detection algorithm f o r that case.
