摘要： An energy efficient connectionless routing method with simple lookup is disclosed for reducing the number of address lookups associated with a message packet. The energy efficient connectionless routing method with simple lookup includes determining a label sequence which will allow the message packet to traverse a plurality of MPLS domains and affixing the label sequence to the header of the message packet. This allows the message packet to traverse a plurality of MPLS domains without requiring a subsequent IP address lookup at every MPLS domain boundary. The energy efficient connectionless routing method with simple lookup is particularly useful for reducing power consumption associated with TCAM operations during IP address lookups. In addition, a Label Sequencing Edge Router is disclosed for performing the method.

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： A method may include allocating channels of a wireless local area network (WLAN) including a plurality of access points to the plurality of access points based on a load of each access point. The load of each access point may include a user load and/or an interference load. The user load may be generated by each user of the access point. The interference load may be based on interference caused by transmissions between the remainder of the plurality of access points and users of the remainder of the plurality of access points.

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： 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.
