A location determination method uses location data items that originate at known locations and are passed to, and diffused between, entities by short-range communication. Each location data item received by an entity includes a displacement value indicative of the displacement of the item since leaving a specified known location. This displacement value of a location data item has been updated to reflect movement of entities temporarily hosting the item and/or the range of the transmission hops made by the item. An entity derives its location from received location data items by effecting a weighted combination of the known locations specified in the received location data items, the weighting of the known location specified in each received location data item being dependent on the associated displacement value.
