An Evaluation Framework of Replication Protocols in Mobile Environment

Conventional data sharing systems are based on presumption that connections are reliable, and a faultyoperation will be considered in case of losing a connection. Flashing connections are characteristic ofmobile devices, which leads to the conclusion that networks are not reliable, and the conventionalapproach might not be the best solution. A possibility to access information in a disconnected situationwould certainly improve availability. This paper presents a framework for comparing the quality ofimportant features from a mobile perspective. The availability, reliability and adaptability have been thethree main criteria which have been considered for evaluation. The objective is to provide decentavailability while sustaining the semantics of information; reliability is thereby important. For dynamicallyevolving environments to provide connectivity and reasonable use of shared resources adaptability is vital.
