Many Aspects of Reliabilities in a Distributed Mobile Messaging Middleware over JMS

Pronto[19] is a middleware system for mobile applications with JMS messaging as a basis in both centralized and decentralized forms. Asynchronous messaging is essential to support reliable communication with mobile devices. An intelligent gateway and smart caching in Pronto support the construction of distributed messaging systems over JMS servers. The main aim of Pronto is to support a reliable and efficient message flow from data source to consumers by applying and comparing different techniques. Pronto provides a solution for mobile application specific problems such as resource constraints, network characteristics, and data optimization, which achieves high reliability in end-to-end communication.
