摘要： Traffic streams through mesh points in a mesh network are managed. Data arriving at the mesh point are aggregated in packet queues. The packet queues segregate arriving data by the data's Quality of Service (QoS) requirement. An appropriate communication channel is selected. The communication channel is accessed through a contention access schema. An M-Request-To-Send (MRTS) message is sent to potential receiving mesh points with receiving mesh points responding with an M-Clear-to-Send (MCTS) message. Data from the packet queues is transmitted to the next mesh point. A mesh point power save mode allows battery operated mesh points to sleep preserving power.

摘要： 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.

摘要： 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.

摘要： Techniques for resolving blinded-node problems are described herein. One aspect operates on the physical (PHY) layer only, which a second layer operates on the medium access control (MAC) layer. Both aspects involve having a node stop processing a data packet that is not destined for it so as to be able to reserve its resources to detect control and other packets. An apparatus for implementing the techniques are also disclosed.
摘要翻译：本文描述了用于解决盲节点问题的技术。一个方面仅在物理（PHY）层上操作，第二层在介质访问控制（MAC）层上操作。这两个方面涉及使节点停止处理不发往其的数据分组，以便能够保留其资源以检测控制和其他分组。还公开了一种用于实现该技术的装置。
