uP: A Lightweight Protocol for Services in Smart Spaces

The use of mobile devices in a cooperative way is a growing trend, especially in ubiquitous environments. It has created a challenge in terms of how best to connect these devices with greater efficiency. The use of distributed service-oriented architectures (like DSOA - Device Service Oriented Architecture), which takes into account mobile devices restrictions, is shown as a natural candidate solution. In this article, we present the uP, a lightweight set of protocols designed to efficiently facilitate communication in a DSOA configuration. Empirical experiments indicate that this approach provides good results, allowing low consumption of energy in mobile devices within a DSOA environment.
