MIRTES: MIddleware for real-time transactions in embedded systems

In this paper we present MIRTES, a project for a data, event, and code-centric middleware with realtime characteristics targeted to wireless sensor networks. The MIRTES architecture and implementation focusing on data-centric services is here proposed together with its experimental validation. At the state of the art for data-centric middleware, packages succeed in providing a database like abstraction of the network supporting SQL-like queries spawned at Service Access Points hosted in high-end devices like PCs. Anyhow none of these packages tackles with the timeliness issue, being developed on top of non real-time technologies for operating systems and network protocols.
