1. An allocation method in a data transmission network on-board a mobile vehicle for transporting passengers, the transmission network comprising a plurality of wireless access points, each access point being configured for transmitting and receiving, on one functioning channel among a plurality of available channels, radio signals between said access point and a plurality of terminals on-board the mobile vehicle,
the allocation method comprising the following steps:
provision of a digital model of the mobile vehicle and of the access points;
for every available channel and for every access point, simulation with the digital model of the propagation of radio signals in the mobile vehicle from said access point on said available channel;
for each available channel, for each access point and for each terminal, determination of an estimated bandwidth associated with the communication between said access point and said terminal on said channel according to the simulation associated with said access point and said channel;
allocation of one of the available channels and one of the access points to each terminal according to the bandwidths which were estimated by an optimization algorithm.
