Abstract

In the modern world Pervasive computing plays a vital role. Distributed computing finds its way in nearly every day to day operations of an individual. We have tried to produce a pervasive computing environment that provides accurate and continual service with the use of a distributed dependency graph generator. In order to provide an accurate service the faulty nodes are segregated from the main stream. In order to provide continual service the distributed dependency graph finds various surrogate nodes that are capable of performing the same functions. This is achieved by making the failed node to move to a safe state and perform sensing but not participate in the Decision Dependency Graph .Once the failed node has recovered; it is permitted to participate in the Decision Dependency Graph.
