一种普适环境下面向服务的事务处理模型

A SERVICE-ORIENTED TRANSACTION PROCESSING MODEL IN PERVASIVE COMPUTING

普适环境具有高移动、极端异构、高自治和开放性的特点,普适环境下的服务组合因其突出的动态性问题,为保证对整个服务运行结果的可靠性和一致性,引入事务处理的机制来进行管理。提出一种在普适环境下面向服务的事务处理模型,在服务的发现、组合及运行中引入事务机制来协调管理,保证了服务组合的可靠一致性,并讨论了模型的系统架构和各模块组成,及应用场景。

Pervasive computing is characterized by high mobility,extreme heterogeneity and high openness.Because of its highly dynamic property,services composition in pervasive computing can be introduced with transactional process mechanism to insure reliability and consistency of the service operation effect.In this paper,we propose a services-oriented transaction processing model in pervasive computing,the transaction mechanism is introduced to services discovery,composition and operation so that reliable consistency of the services composition is guaranteed.Its system architecture and constitution of each modules as well as application scenario are discussed in the paper as well.
