摘要： A device (100) and method for frequency scanning uses two radios. The device (100) includes a processor (515), a scan radio (130) including a receiver (135) coupled to the processor (515), and a data radio (105) including a transmitter (115) that is also coupled to the processor (515). The processor (515) determines a transmission schedule for the transmitter (115) of the data radio (105) in response to a capability to receive a frequency scanning signal at the receiver (135) of the scan radio (130).

摘要： A method is provided for enabling periodic scanning in a mesh network. The method includes transmitting from a first access point an announcement that it will be temporarily unavailable, wherein the announcement includes: a first information element for quieting a station associated with the access point during a time period; and a second information element for instructing a neighboring access point to temporarily suspend transmissions to the access point during the time period that the stations are quieted.

摘要： A method is provided to determine optimal data rate and packet length in mobile networks. The method directly determines the optimal packet length (L) and data rate (D), which allows fast convergence in the mobile channel. The method automatically identifies and quantifies channel conditions, as well as adjusts parameters according to changes of channel conditions. A variable (Channel condition Index (CCI)) is abstracted from simulations and then used to describe and quantify the impact of three components of channel conditions: signal-to-noise ratio (SNR), multipath environment and velocity. Based on packet completion rate (PCR) status, the channel condition is identified in terms of CCI value. Once CCI is identified, the model of effective throughput G is directly optimized to locate the best packet length (L) and data rate (D).

摘要： Disclosed are methods including a new optimization criterion, Maximum Mesh Coverage (MMC) for a channel selection process during the formation of ad hoc networks. By using MMC, the intelligent access point (IAP) will select a channel to connect as many mesh nodes as possible in addition to meeting the interference minimization requirement. During mesh formation, the channel interference information for a node is first scanned by the node and then broadcast in its available channels. An iteration procedure for meshing network formation allows the IAP to gradually obtain the global channel interference information and broadcast the same so that a maximum number of n-hop nodes communicate on the same frequency channel. If a channel change is required to accommodate the channel interference status of candidate nodes, a channel change message will be broadcast to better achieve the large coverage advantage of a multi-hop configuration.
