Um modelo de replicação com garantia de consistência em ambientes P2P com mobilidade

Abstract

In unstructured distributed P2P systems there is no logical structure to control the peers coming and leaving the network, which can occur anytime due to mobility. Thus, data exchange with consistence, and data availability are very important. To favor high data availability and to acquire performance gains in dynamic behavior environments, P2P systems use data replication. However, current replication data models have a single failure point, or require complex conciliation algorithms to acquire consistency. This work introduces a replication data model that simplifies the consistency mechanism.
