Independent Dependency Tracking in a Mobile Adhoc Computing Environment

Applications requiring long duration mobile computing activity depend on consistent global state. Existing procedures for estimation of consistent global states (within distributed systems) add message overheads and delays. We propose independent dependency tracking by tracking total cumulative dependence. It is able to prevent cascading of rollback of dependent states. It also facilitates independent calculation of consistent global snapshot by a mobile process. A most recent global snapshot can be independently generated for host recovery. In case of recovery (after a failure), only one message needs to be sent, to inform about the occurrence of a failure, to each connected station
