Process for Routing Data Packets in a Mobile Node Network and Associated Terminal
First Claim
1. A method of routing one or more data packets (P) between a source node (S) and a target node (C) in an ad hoc network comprising a plurality of mobile nodes (1-14;
- R0-R5) moving on traffic routes (L1, L2, L3, C1, C2, C3) of a particular geographical network (10) forming between them a plurality of intersections (I1-I6;
Ii, I10, I20, I30;
In, In+1), wherein the method includes;
a step (E3) of a carrier node (1;
S) of a data packet (P) to be routed to the target node (C) selecting a destination intersection (I2;
I20) from candidate neighbor intersections as a function of traffic conditions;
a step (E7;
E9) of seeking one or more neighbor mobile nodes (2, 3) of the carrier node (1) of the data packet (P) nearer the selected destination intersection (I2) than the carrier node; and
if one or more neighbor mobile nodes (2) is found, a step (E13) of transferring the data packet (P) from the carrier node (1) of the data packet to said neighbor node (2) that has been found so as to route said data packet toward the selected destination intersection (I2).

Abstract
A method of routing data packets (P) between a source node (S) and a target node (C) in an ad hoc network comprising mobile nodes (1-14) that can be located and moving on traffic routes (L1, L2, L3, C1, C2, C3) of a particular geographical network (10) forming between them a plurality of intersections (I1-I6). This method comprises a destination intersection selection step in which a carrier node (S) of the packets (P) selects a destination intersection (12) from neighbor intersections and according to traffic conditions; a step of seeking one or more neighbor mobile nodes (1) of the packet carrier node nearer the selected destination intersection (12) than the carrier node; and, if one or more neighbor mobile nodes (1) are found, a step of transferring the packets (P) from the packet carrier node (S) to the neighbor node (1) that has been found, so as to route the data packets to the selected destination intersection.
