Abstract:
1. A method of routing one or more data packets between a source node and a target node in an ad hoc network comprising a plurality of mobile nodes moving on traffic routes of a particular geographical network forming between them a plurality of intersections, wherein the method comprises: a step of a carrier node of a data packet to be routed to the target node selecting a destination intersection from candidate neighbor intersections as a function of traffic conditions; a step of seeking one or more neighbor mobile nodes of the carrier node of the data packet nearer the selected destination intersection than the carrier node; and if one or more neighbor mobile nodes is found, a step of transferring the data packet from the carrier node of the data packet to said neighbor node that has been found so as to route said data packet toward the selected destination intersection, wherein a step of selecting a new destination intersection is executed if the carrier node of the data packet is located at the selected destination intersection, referred to as a current intersection, and wherein during the selection step the carrier node of the data packet selects a destination intersection from the candidate neighbor intersections as a function of one or more real time traffic conditions on a traffic route connecting the respective candidate intersection to the current intersection.
