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.

Method of broadcasting data packets in a network of mobile nodes and associated terminal

A method of broadcasting a data packet (D) in an ad hoc network comprising a plurality of groups of mobile nodes traveling along traffic lanes in a road network. The data packet (D) is broadcast within a group (G) during an intragroup broadcasting phase during which the data packet (D) propagates simultaneously in two opposing directions of movement (A, A), such that the packet (D) is received by peripheral nodes (B, B) of the group (G). During an intergroup broadcasting phase, a peripheral node (B) transmits the data packet (D) to another group.
