    JADE OsMoSes

    OSGi based Mobility Services for the JADE mobile agent framework

    JADE OSGi (based) MObility SErviceS (OsMoSes) is an OSGi based set of services that offers an alternative to the "built-in" mobility service of JADE. This project aims to bring to the JADE framework all the benefits of the OSGi technology, allowing to modularize the "agents" into "bundles" and migrate them in a transparent way. Currently this project is in a "proof of concept" stage and is looking for the community's interest to keep evolving into a full fledged product. Please refer to the wiki (http://sourceforge.net/p/jade-osmoses/wiki/Home/) for more information about the project.
