the software technology on the development of intelligent health solutions and their associated medical systems. By making a biased survey centered in the work of some researchers, the paper exposes selected contributions of a limited part of the research community that target at developing distribution software; this is an exercise to analyze these specific contributions that feed the author’s background and will take them as basis for producing a new enhanced solution tailored to the needs of medical device interoperability.

Paper structure {#sec:structure}
---------------

The paper is structured as follows. Section \[sec:rolemw\] describes the role of the distribution software for developing distributed medical applications, emphasizing the web technology that facilitates interoperability via standard protocols. Section \[sec:group\] describes state of the art on middleware design and distribution, focusing on the work of the author’s group that serves as his reference for improving middleware design for medical systems; also, other technologies are listed that are relevant for his current work. Section \[sec:standards\] describes illustrates some examples of frameworks for medical devices coordination and interoperability projects. Section \[sec:conclusion\] presents the conclusions and the future work that will be part of the author’s thesis.
