Abstract
Information with local relevance is diffused locally using mobile devices equipped with non-wired short-range communication means, the information being propagated from an originating point in messages passed from device to device in an unstructured way. The devices implement measures for limiting message propagation including controlling propagation of a message from a particular originating point (OP1) in dependence on the prominence of the occurrence of that originating point in a set of most recently received messages.
