摘要： Real-time broadcast and multicast based packet transmissions/services over a wireless, local area networks (WLAN) may be improved by reducing the interference across neighboring access points (APs) while minimally impacting the performance of unicast transmissions/services. Minimal impact is assured by scheduling the transmission of multicast packet flows such that the duration of the time period required to transmit such flows is also minimized. One type of method provides a constant approximation of an optimal time period/schedule while another provides a logarithmic approximation of an optimal time period/schedule.

摘要： A power aware Point-Of-Presence design and auto-configuration method is disclosed for configuring which network elements within a point-of-presence are powered so as to accommodate anticipated traffic while minimizing power consumption. The IP power aware Point-Of-Presence design and auto-configuration method includes a set of activation thresholds associated with each port in the Point-of-Presence that indicates that the port should be activated when the traffic demand exceeds the threshold. The power aware Point-Of-Presence design and auto-configuration method is particularly useful for providing a configuration which accounts for both external and internal link traffic demand and has the further advantage of ordering the port activation such that only a minimum number of activation and deactivation operations to satisfy a new demand is required. This property is advantageous for limiting the routing instabilities caused by topological changes in response to varying demand.

摘要： The number of directional antennas and associated radios needed to ensure a nomadic wireless mesh network (NWMN) remains operational in the event of node or link failures, while minimizing delay and other unwanted effects, may be determined using novel methods and devices. Such a determination may reduce the number of antennas and radios a service or network provider normally uses, thus reducing its costs.

摘要： Unique identifiers are assigned to sets of adjacent access points in a wireless, local area network (WLAN). Thereafter, a unique identifier may be forwarded to a mobile device which uses the identifier to associate itself with one of the adjacent access points. Associating a mobile device with an adjacent access point using unique identifiers allows a WLAN to meet its load balancing objectives.

摘要： A more energy efficient, medium access control (MAC) layer of a multi-hop wireless network is provided using scheduling techniques which reduce packet collisions, and therefore the need for packet re-transmissions, while ensuring both bandwidth and delay, Quality-of-Service (QoS) guarantees. The techniques are used in conjunction with the formation of a multi-hop, configurable access wireless network (CAN).

摘要： Wireless stations (and their associated operation) making up a static, multi-hop wireless network are simplified because topological modeling and routing/scheduling decisions are shifted from the stations to a controller external to the network. The controller may determine routing paths and schedules for each of the wireless stations in a network based on the topology of a given network along with other network characteristics. Thereafter, the so-determined paths and schedules are sent to the associated wireless stations. By simplifying the operation of a wireless station, the amount of energy required to be used by each station may be reduced thereby maximizing the lifetime of the network.
摘要翻译：由于拓扑建模和路由/调度决策从站点移动到网络外部的控制器，所以构成静态多跳无线网络的无线站（及其相关操作）被简化。控制器可以基于给定网络的拓扑以及其他网络特性来确定网络中的每个无线站的路由路径和调度。此后，将所确定的路径和时间表发送到相关联的无线站。通过简化无线站的操作，可以减少每个站要使用的能量的量，从而最大化网络的使用寿命。

摘要： The coordination of transmissions by access points (APs) in a wireless local area network (WLAN) is carried out by allowing APs to transmit during slots of a Contention Free Period (CFP). Prior to transmission, slots are assigned to APs using a 4-approximation technique. This technique allows an AP to transmit using multiple frequencies. The assignment of slots satisfies a maximal, lower bound of an AP slot-to-user ratio.
摘要翻译：无线局域网（WLAN）中的接入点（AP）的传输协调通过允许AP在无竞争周期（CFP）的时隙期间进行传输。在传输之前，使用4近似技术将时隙分配给AP。这种技术允许AP使用多个频率进行传输。时隙的分配满足AP时隙到用户比率的最大下限。
