Geo-registers : an abstraction for spatial-based distributed computing
Résumé
In this work we present a novel abstraction that allows a set of distributed processes, aware of their respective positions in space, to collectively maintain information associated to an area in the physical world. This abstraction is a logical object shared between participating processes and provides two operations, namely read and write, as for traditional registers. This paper provides a specification and implementation of such a shared object for non concurrent writes and multiple readers, then describes a possible extension to concurrent writes. We also provide insights on how this kind of objects could be useful to program location-aware applications .
