摘要： A method provides access to a channel in a network including stations and an access point connected by a common wireless channel. A station makes a request to the access point to access to the channel to transmit a data stream. The access point assigns a sequence index value to the data stream. The sequence index value is broadcast by the access point. Then, the station transmits the data stream, during a contention free period, at a time corresponding to the sequence index value.

摘要： A system and method schedule series of packets for transmission between terminals in a single wireless channel of a packet-switched local area network. The local area network can operate in an ad hoc mode or in infrastructure mode. A transmission rate is assigned to each of the terminals. The terminals can be mobile. Different terminals can be assigned different transmission rates, depending on a quality of the channel. That is, terminals transmitting via an error-free channel are assigned a higher transmission rate than terminals transmitting via an error-prone channel. Then, the series of packets are scheduled for transmission between the terminals such that each terminal receives a substantially equal amount of transmission time over an extended period of time.

摘要： Techniques for enhancing throughput capacity and/or bandwidth distribution fairness among APs in a wireless network are described. Specifically, a channel frequency profile which includes a center frequency and channel-width (i.e., channel bandwidth) is dynamically assigned to each of one or more APs in a wireless network. The assigned channel frequency profile for each AP is based, at least in part, on the current composition of the wireless network including, its topology and traffic load distribution. In this regard, each AP's channel frequency profile can be continuously or periodically changed such that the entire available frequency spectrum is effectively utilized and/or interference between APs is avoided or limited. This, in turn, enhances the throughput capacity and/or bandwidth distribution fairness of the wireless network.

摘要： A new media access control (MAC) protocol for cognitive wireless networks is described. The new MAC protocol allows each of multiple nodes, such as cell phones and computers with wireless, to determine utilization of a communication spectrum, such as the television broadcast band. The nodes collaborate to achieve a combined view of spectrum utilization in their local vicinity, in which scheduled users and empty time segments are mapped across a wide range of frequencies. Nodes negotiate with each other to reserve idle segments of the spectrum for packet exchange on negotiated frequencies. Control packet structure allows nodes to become prescient of the local spectrum utilization during handshaking. A cognitive device operating under the new MAC has a first radio that both scans the spectrum and monitors a control channel; and a second reconfigurable radio with adjustable parameters, including frequency and bandwidth, for packet transmission.
