O esquema de consistência otimista foi estabelecido com relação à consistência e disponibilidade de dados em sistemas distribuídos. O modelo nômade de consistência de dados que usa vetores de versão para suportar o versionamento de dados para sincronização de dados e detecção de conflitos simultâneos é adequado para um sistema de replicação otimista que suporta redes sem fio de grande escala. Este artigo descreve a arquitetura e seu modelo de consistência de dados utilizando versionamento de dados e seu controle de domínio de acesso voltado para sistemas nômades de compartilhamento de dados, como trabalhos colaborativos utilizando banco de dados e mensagens, e as otimizações de transferência de dados do modelo. Avaliamos nosso esquema de versionamento de dados comparando com um versionamento de dados tradicional e a otimização da transferência de dados por estimativa e medição assumindo o trabalho de um trabalhador móvel. Geramos fórmulas aritméticas para estimativa de transferência de dados usando técnicas de otimização e as aplicamos a configurações de compartilhamento de dados em grande escala nas quais grupos de colaboração são formados dinamicamente e dados são trocados em cada grupo. O versionamento de dados com domínio de acesso aumenta a flexibilidade em configurações de compartilhamento de dados, como sistemas de colaboração móvel e sistemas móveis do tipo cliente/servidor. Confirmamos que a combinação das otimizações gerais e das configurações de domínio de acesso baseadas em nosso modelo de consistência de dados é aplicável para sistemas de compartilhamento de dados móveis em larga escala.

Abstract: The optimistic consistency scheme has been established with respect to data consistency and availability in distributed systems. The nomadic data consistency model using version vectors to support data versioning for data synchronization and concurrent conflict detection is suitable for an optimistic replication system that supports large-scale wireless networks. This paper describes the architecture and its data consistency model using data versioning and its access domain control targeted for nomadic data sharing systems, such as collaborative works using database and messaging, and the data transfer optimizations of the model. We evaluate our data versioning scheme comparing with a traditional data versioning and the data transfer optimization by estimation and measurement assuming a mobile worker's job. We generate arithmetic formulas for data transfer estimation using the optimizing techniques and apply them to large-scale data sharing configurations in which collaboration groups are dynamically formed and data is exchanged in each group. The data versioning with an access domain increases flexibility in data sharing configurations, such as mobile collaboration systems and client/server type mobile systems. We confirmed that the combination of the general optimizations and the access domain configurations based on our data consistency model is applicable for large-scale mobile data sharing systems.
