The middleware infrastructure to support applications is becoming critically important to the new horizons of mobile and pervasive computing. In this context, the goal of our work is to propose architecture and a prototype of a middleware which is adapted to the usage and the requirements of the future mobile systems. While message oriented middleware (MOM) is an established concept for a long time on the fixed environments, we work to put forward the idea that it proposes an effective solution of many issues in the mobile environments. Our contribution is to bring current MOMs closer to the specifities of these environments, through providing more adaptability and context-awareness, and also through supporting more specific problems like intermittent connection and multi-network access.
