Abstract: One or more stations are sorted based on respective load levels, and a reuse pattern is generated, based on the sorted load levels and mapped interference levels, including one or more reuse sets of stations capable of sharing a transmission resource. The stations within each reuse set are listed in order based on their respective load levels, and an additional station is added to a reuse set, as long as the cumulative transmission level within the reuse set is below a threshold interference level and the additional station is not already listed in another reuse set. A network schedule is updated based on the reuse pattern to increase bandwidth efficiency in the network.

Abstract: Interference levels occurring at one or more stations are mapped, and a reuse pattern is generated, based on the mapped interference levels, including one or more reuse sets of stations capable of sharing a transmission resource. The stations within each reuse set are listed in increasing order based on their respective interference levels, and an additional station is added to a reuse set, as long as the cumulative interference level within the reuse set is below a threshold interference level and the additional station is not already listed in another reuse set. A network schedule is updated based on the reuse pattern to increase bandwidth efficiency in the network.

Abstract: Interference levels occurring at one or more stations in a wireless network, where each of said one or more stations is a base station or a relay station. The measured interference levels are mapped by building a first matrix including noise plus interference occurring at each of the one or more stations, respectively, and scheduled transmissions at predetermined times by each relay station respectively are mapped by building a second matrix. The first matrix and the second matrix are multiplied in order to determine the noise plus interference impact upon each base station by each relay station so that a network schedule can be generated in order to increase bandwidth efficiency in the network.

Abstract: A security management approach that combines network security management with application layer or software service security to address the threat of internal network security attacks. The invention is directed to a method for enhancing network security on a computer network. Data access privileges relating to users and services are interpreted, network access rules are determined based on the interpreted privileges, and network message traffic is monitored and filtered based on the determined network access rules. The interpreting, determining, monitoring, and filtering are performed at a network layer responsible for controlling how a network device gains access to the network, such as the Media Access Control (MAC) layer.

Abstract: Disclosed is a wireless station having a receiver and a network allocation vector associated with each of a plurality of directional antennas. The receivers concurrently listen for frames from remote stations. When any receiver detects a frame from a remote station, the receiver activates its associated NAV. The station has one or more transmitters that can transmit using the antennas. While transmitting a signal using an antenna, the receivers associated with any non-transmitting antennas continue to listen for signals from remote stations. The station cancels any signals from the transmitting antenna received by the non-transmitting antennas. To perform the cancellation, the station performs a self-calibration procedure. The station can self-calibrate by either silencing neighboring stations or by inserting null tones into a transmitted calibration signal.
