Disclosed is a periodic broadcasting of data packets in an ad hoc network formed by a plurality of mobile nodes that can move along traffic lanes forming junctions and can be located. A data packet is broadcast by a broadcaster node elected from a set of candidate nodes at each junction. The broadcaster node is elected in a decentralized manner at each candidate node by comparing the estimated travel time to reach the center of the junction with a particular reference time period between two successive broadcasts.
The method according to claim 1, wherein, during said election step, said candidate node calculates a waiting time, the value of the calculated waiting time decreasing as the estimated travel time of said candidate node to the center of said cell approaches a predetermined reference time period, and wherein at the end of said waiting time said candidate node broadcasts a notification message reporting that it has been elected broadcaster node if it has not received any such notification message from another node.
The method according to claim 1, wherein the geographical space is a traffic network comprising a plurality of traffic lanes forming between them a plurality of junctions and wherein said cell is associated with a junction.
A mobile node of a network comprising a plurality of communicating mobile nodes, said mobile node including:
A computer program including instructions for executing the steps of the broadcasting method according to claim 1 when said program is executed by a computer.
The computer-readable storage medium storing a computer program including instructions for executing the steps of the broadcasting method according to claim 1.
