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。

摘要： An IP fast reroute scheme offering full protection is disclosed for reducing the number of address lookups associated with a message packet. The IP fast reroute scheme offering full protection includes a router configured to forward the arriving packet to a next-hop neighbor node according to one of a first pointer and a second pointer associated to a destination node in a forwarding information table stored in a forwarding information memory storage; the first pointer is directed to a first next-hop neighbor node which is on the shortest path from the network node to the destination node; and the second pointer is directed to a second next-hop neighbor node different from the first next-hop neighbor node, the second next-hop neighbor node on a candidate cycle containing both the network node and the destination node having the greatest overlap with a sink tree rooted at the destination node. The IP fast reroute scheme offering full protection is particularly useful for providing full protection against single link and node failures with a simple method requiring no packet modifications.

摘要： Methods and apparatus are provided for improved coverage verification schemes in a wireless sensor network that do not require information about the location of sensor nodes in the wireless sensor network. Coverage holes are detected by a first node in a wireless sensor network by obtaining an estimate of a distance to each of a plurality of additional nodes in a transmission radius of the first node; determining a relative location of each of the plurality of additional nodes in the coordinate system of the first node; identifying border segments of a sensing border of the first node, where each of the border segments comprises a section of a sensing border of the first node that is covered by a sensing radius of at least one of the additional nodes; and determining if a coverage hole exists for the first node by determining if a plurality of the border segments comprise a cyclic segment sequence. The coordinate system comprises r-map coordinates of the first node and the additional nodes, where r is based on a transmission radius of the first node.

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.
