Bounding recovery time in rollback-recovery protocol for mobile systems preserving session guarantees

Abstract

This paper addresses a problem of integrating the consistency management of session guarantees with recovery mechanisms in distributed mobile systems. To solve such a problem, rollback-recovery protocol rVsSG, preserving session guarantees is proposed. The protocol employs known rollback-recovery techniques, however, while applying them, the semantics of session guarantees is taken into account. Consequently, rVsSG protocol is optimized with respect to session guarantees requirements. The paper includes the proof of safety property of the presented protocol. © IFIP International Federation for Information Processing 2006.
