摘要: Systems and methodologies are described that facilitate communication in a wireless network environment. In particular, access points can dynamically adjust transmit power and/or carrier-sensing thresholds to allow multiple access points to communicate concurrently. In aspects, access points exchange node information, including RSSI and node addresses, of nearby nodes. The node information can be utilized to detect hidden nodes and estimate interference levels. Transmit power and/or carrier-sensing thresholds can be modified as a function of distance between source and destination access points, interference from hidden nodes, transmission rates, and/or path loss.

摘要: Techniques for using at least one of omni-directional and directional antennas for communication are described. A station may be equipped antenna elements selectable for use as an omni-directional antenna or one or more directional antennas. The station may select the omni-directional antenna or a directional antenna for use for communication based on various factors such as, e.g., whether the location or direction of a target station for communication is known, whether control frames or data frames are being exchanged, etc.

摘要: 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.

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.
