摘要： A clustering based load adaptive sleeping protocol for ad hoc networks includes a plurality of nodes forming a cluster, where the nodes in the cluster are partitioned into n groups. This partitioning is performed based on the node ID (e.g. node_id modulo n). The cluster head transmits a beacon at fixed intervals. The beacon interval is divided into N slots, where N is a multiple of n. Node sleep/activation times are synchronized to the beacon interval slots. The node's group number is used to determine the slots within a beacon interval that a node begins it s sleep cycle. Therefore, no additional signaling is required between nodes to indicate sleep patterns. The sleeping time of each node may be increased when extended periods of inactivity are detected according to an adaptive procedure.

摘要： An advance over the prior art is achieved through an efficient method for an admission control algorithm and a scheduling mechanism that complement each other in providing the following three classes of service. A first class of service is termed Class 1 where users specify a nominal amount of bandwidth desired. A second, lower tier service class is termed Class 2, wherein users specify a nominal and minimum amount of bandwidth desired when entering into a network connection. A third server class is Class 3, where Class 3 users are treated as best effort users. For Class 1 users the methodology of the present invention provides a guaranteed nominal amount of bandwidth. The admission control procedure ensures that Class 1 users are admitted only if resources exist to satisfy the nominal bandwidth requirements of the Class 1 users. Class 2 users are admitted if resources exist to satisfy the minimum bandwidth requirements of the user. Class 2 users are served with a bandwidth of up to their nominal bandwidths if there is capacity left after serving the Class 1 users with their nominal capacities. Class 3 users are served only if the Class 2 users have received their nominal bandwidths.
摘要翻译： 通过用于准入控制算法和调度机制的有效方法来实现现有技术的进步，所述准入控制算法和调度机制在提供以下三类服务时相互补充。 第一类服务被称为1类，用户指定所需的额定带宽量。 第二个较低级别的服务类称为2类，其中用户在进入网络连接时指定所需的标称和最小带宽量。 第三个服务器类是Class 3，其中Class 3用户被视为尽力而为的用户。 对于1类用户，本发明的方法提供了有保证的标称带宽量。 接纳控制程序确保只有在存在资源以满足1类用户的标称带宽要求的情况下才允许1类用户。 如果存在资源以满足用户的最低带宽要求，则允许2类用户使用。 如果在服务具有标称容量的Class 1用户之后剩余容量，则Class 2用户的带宽可达到其标称带宽。 仅当Class 2用户已经收到其标称带宽时才能使用3级用户。

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： Techniques and apparatus for controlling the transmit power of an uplink (UL) signal from a user terminal in a wireless communications system in an effort to achieve some target characteristic, such as a target carrier-to-interference (C/I) ratio, at an access point (AP) are provided. In this manner, such a user terminal may help avoid or compensate for imbalances in received radio frequency (RF) power between UL signals received from multiple user terminals by the AP. For example, the transmit power at each user terminal may be controlled in an effort to achieve a target post-processing C/I ratio of 28 dB per spatial stream in an effort to reduce large power imbalances and optimize throughput per user terminal. The user terminal and the AP may compose part of a multiple-input multiple-output (MIMO) communication system utilizing spatial-division multiple access (SDMA) techniques.

摘要： An adaptable decision parameter is used to determine whether to react to resource utilization messages. The decision parameter may comprise a decision threshold that is adapted based on received resource utilization messages. The decision parameter may comprise a probability that is used to determine whether to react to a received resource utilization message. Such a probability may be based on, for example, one or more channel conditions, the number of interferers seen by a node, the number of received resource utilization messages, or some other form of resource utilization message-related information.

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.
