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. For a device that is arranged to propagate a received message multiple times, these measures include increasing (75) the interval between retransmissions in dependence on how many times the same message has been received by the device either in total or during a recent period.
