Data Transfer Evaluation of Optimistic Data Consistency Model

概要

論文の詳細を見る
There are two basic consistency schemes, pessimistic consistency and optimistic consistency, with respect to data consistency and data availability. The optimistic consistency model is suitable for high latency wireless networks. This paper describes data versioning and its access control scheme to reduce data transfer for data synchronization, discuss how to reduce the data transfer size for synchronization. We evaluate the data size reduction by generating arithmetic formulas in each optimizing technique and confirm that the formulas are tolerable in determining the data size of large scale mobile data sharing system. Lastly, we recognize that two parameters to define access domain showed the flexibility of system configuration and effectiveness in data synchronization.
