Theoretical model (mostly) worked out

Tool support pending

Class projects (1)Class projects (1)DRADEL

Extend it to support peer interactionsExtending the spec with dependency tag associated with each provided service of a componentExtending the spec with degraded mode tag associated with each provided service of a component

Utilize this information at the level of implementation

µDRADELHow much can be deployed on devices?Under what circumstances?

Border connectorsExtending them to monitor message frequencies and report the frequencies on demand

Must be highly efficientMeasure the penalty

Supporting reconnection

Class projects (2)Class projects (2)

PrismExtend it with automated discovery of network nodes and software components on those nodesAdd peer supportAdding source parameter to the component descriptionPing attached devices and visually depict disconnection

Disconnected operationSuggest ways to construct a dependency graph of components so that benefit can be calculated preciselyDetect the disconnectionCalculate the probability of sudden disconnection
