Abstract: An apparatus and method of controlling a traffic stream in a mesh network comprising receiving at a second node a traffic stream admission request to admit a traffic stream from a first node, determining a traffic load for the second node, and determining whether to admit or deny the traffic stream from the first node using the traffic load.

Abstract: Flows admitted to a mesh node may be controlled through contention access parameters. The admitting node may determine a desired transmission opportunity duration, and a transmission opportunity frequency. Furthermore, the node may achieve the flow rate and delay bound requirements of the admitted flow based at least in part upon the desired transmission opportunity duration, and the transmission opportunity frequency. The data rate and the access frequency of the admitted node may be monitored at the physical access level. The flow rate requirement may be accomplished based at least in part upon an adjustment to the transmission opportunity duration. The delay bound requirement may be accomplished at least in part upon manipulation of the contention access parameters. The transmission opportunity duration and the access parameters may be determined by the upstream admitting nodes, which may reduce congestion near mesh portals, and accomplish increased data transfer.

Abstract: An apparatus includes a processing system configured to establish a link with any one of a plurality of access points in a mesh network, each of the access points providing the apparatus with a different data path through the mesh network. The processing system is further configured to compute a metric for each of the data paths and select one of the access points to establish the link with based on the metrics. In a centralized mesh network, an apparatus includes a processing system configured to compute, for each of the access points, a metric for each of a plurality of data paths supportable by that access point, and establish interconnections between the access points based on the metrics.

Abstract: Los flujos admitidos a un nodo de la malla pueden ser controlados a través de los parámetros de acceso de contencion. El nodo de admision puede determinar una duracion de oportunidad de transmision deseada, y una frecuencia de oportunidad de transmision. Más aun, el nodo puede lograr la velocidad de flujo y los requerimientos de límite de retardo del flujo admitidos, sobre la base, por lo menos en parte, en la duracion de oportunidad de la transmision deseada, y la frecuencia de oportunidad de transmision. La velocidad de datos y la frecuencia de acceso del nodo admitido puede ser supervisada en el nivel de acceso físico. El requerimiento de la velocidad de flujo puede ser logrado sobre la base, por lo menos en parte, en un ajuste a la duracion de oportunidad de transmision. El requerimiento de límite de retardo puede ser logrado, por lo menos en parte, en la manipulacion de los parámetros de acceso de contencion. La duracion de oportunidad de transmision y los parámetros de acceso pueden ser determinados por los nodos de admision de corriente ascendente, los cuales pueden reducir la congestion cerca de los portales de la malla, y lograr el incremento de la transferencia de datos.

Abstract: Techniques for controlling transmissions in wireless communication networks are described. In one aspect, transmission control for a mesh network may be achieved by ranking mesh points or stations in the mesh network. In one design, the rank of a first station in the mesh network may be determined. At least one station of lower rank than the first station in the mesh network may be identified. At least one transmission parameter for the at least one station of lower rank may be set by the first station. In another aspect, stations may be assigned different transmission parameter values to achieve the data requirements of each station. At least one transmission parameter value may be selected for each station based on the rank, QoS requirements, amount of traffic, and/or achievable data rate for that station and may be sent (e.g., via a probe response message) to the station.
