Title (EN) METHOD FOR CONTROLLING THE ACCESS TO A TDMA WIRELESS CHANNEL FROM NODES OF A NETWORK OF EITHER LINEAR OR TREE TOPOLOGY
(FR) PROCEDE DESTINE A CONTROLER L'ACCES A UNE VOIE SANS FIL AMRT A PARTIR DE NOEUDS D'UN RESEAU DE TOPOLOGIE LINEAIRE OU ARBORESCENTE
Abstract:
(EN) A MAC method for hierarchial multihop wireless network is directly utilizable with mesh architecture specified in IEEE 802.16x. The requests of resources for sending uplink flows towards the BS, and/or downlink flows towards end nodes is/are computed by each requesting node on the end-to-end basis instead of only the next link towards destination. In practice, each requesting node issues a cumulative request given by summing up the same request for each link separating the node from the Base Station (in uplink) plus each link separating the Base Station from the destination node (in downlink) . Such requests enable the centralized node (Base Station) to perform a connection based scheduling. The Base Station in response to all cumulative requests grants uplink and/or downlink resources for each link. If the amount of resources requested is below the maximum net throughput on MAC layer, the profile of grants is equal to the profile of requests. In case the amount of requested resources is not below the maximum net throughput on MAC layer, the ideal profile of grants is normalized with respect to ratio between the maximum net throughput on MAC layer and the amount of the overall requested resources .
(FR) Selon l'invention, un procédé MAC destiné à un réseau sans fil à sauts multiples hiérarchique est directement utilisable avec une architecture maillée spécifiée dans IEEE 802.16x. Les demandes de ressources pour l'envoi de flux montants vers la station de base et/ou de flux descendants vers les noeuds terminaux sont calculées par chaque noeud demandeur sur une base de bout en bout et non plus uniquement sur la base de la liaison suivante vers la destination. En pratique, chaque noeud demandeur émet une demande cumulative donnée par récapitulation de la même demande pour chaque liaison séparant le noeud de la station de base (en liaison montante) plus chaque liaison séparant la station de base du noeud de destination (en liaison descendante). Ces demandes permettent au noeud centralisé (station de base) de réaliser un ordonnancement basé sur la connexion. En réponse à toutes les demandes cumulatives, la station de base affecte des ressources de liaison montante et/ou de liaison descendante pour chaque liaison. Si la quantité de ressources demandées est inférieure au débit net maximal sur la couche MAC, le profil des affectations est égal au profil des demandes. Si la quantité de ressources demandées n'est pas inférieure au débit net maximal sur la couche MAC, le profil idéal des affectations est normalisé en termes de rapport entre le débit net maximal sur la couche MAC et la quantité des ressources demandées dans leur ensemble.
