CA 2502938

A wireless communication network includes a plurality of mobile nodes each including a transceiver (14), a phased array antenna (16) connected to the transceiver, and a controller (18) connected to the transceiver. The controller initiates at least one semi-permanent time slot request for respective time frames to establish a communication link with each neighboring mobile node and leaving at least one available time slot in each time frame, while processing multiple received semi-permanent time slot requests from neighboring mobile nodes. The controller also initiates at least one available time slot request to also serve the communication link with a neighboring mobile node based upon link communications demand, while processing multiple received available time slot requests from neighboring mobile nodes. The phased array antenna is aimed by the controller towards each neighboring mobile node during communication therewith.

L'invention concerne un réseau de communication sans fil comprenant une pluralité de noeuds mobiles. Chaque noeud mobile comprend un émetteur récepteur (14), une antenne réseau à commande de phase (16) connectée à l'émetteur récepteur, et un contrôleur (18) connecté à l'émetteur récepteur. Le contrôleur lance au moins une demande de créneau temporel semi-permanent pour des trames temporelles correspondantes, afin d'établir une liaison de communication avec chaque noeud mobile voisin, en laissant au moins un créneau temporel disponible dans chaque trame temporelle, tout en traitant plusieurs demandes de créneau temporel semi-permanent reçues provenant de noeuds mobiles voisins. Le contrôleur lance également au moins une demande de créneau temporel disponible pour servir également la liaison de communication avec un noeud mobile voisin, en fonction d'une demande de communication de liaison, tout en traitant plusieurs demandes de créneau temporel disponible reçues provenant de noeuds mobiles voisins. L'antenne réseau à commande de phase est pointée, par le contrôleur, vers chaque noeud mobile voisin lors de la communication avec ceux-ci.
