1. A method of estimating a density of mobile nodes of an ad hoc network in which the mobile nodes move along roads of a particular geographical network, at least some mobile nodes being configured to locate themselves in the geographical network and configured to maintain an up-to-date neighbor table including information relating to positions of their neighboring mobile nodes, wherein a density of the mobile nodes on a road is determined by the steps of:

  • subdividing said road into coverage cells;

    executing an intracellular count at one of said coverage cells during which a mobile node located in a predetermined central area of a coverage cell comprising a principal node determines from its neighbor table local traffic density data; and

    performing an aggregation, during which said principal node inserts the determined local traffic density data into a cell density packet.
