摘要： Techniques are provided for selecting a root node in an ad hoc network that contains a plurality of nodes including a first node. According to one implementation of these techniques, a first node can receive a message from at least one of the other nodes. Each message includes a number of primary factors associated with a particular node regarding capabilities of the particular node. The primary factors associated with each node can then be evaluated, and an attempt can be made to select the root node based on the primary factors associated with each node. If the first node is unable to select the root node based on the primary factors associated with each node, then the root node can be selected based on secondary factors associated with each node.

摘要： A method and system for data transmission by computational devices in a wireless network (100) are disclosed. A computational device (102) organizes the wireless network in a hierarchical topology having at least one root node and updates a list of interferers and a list of descendents. Then, the computational device allocates a Contention Free Period (CFP) slot to each computational device in the wireless network based on at least one of the list of interferers and the list of descendents and transmits data during the allocated CFP slot.

摘要： Method and apparatus for packet scheduling in a wireless network is described. First values for a data transmission rate are measured for each of a plurality of mobile stations over time. Second values for a function of the data transmission rate are computed using at least one of the first values for each of the mobile stations. A rate of change of the data transmission rate is computed for each of the plurality of mobile stations using the second values associated therewith. A stability of the data transmission rate is computed for each of the plurality of mobile stations using the second values associated therewith.

摘要： A method for communicating beacon transmissions from a wireless access point (WAP) to a client transceiver in a wireless local area network (WLAN) system (500) includes obtaining a reference timing for the wireless access point (WAP) (502). The sector configuration and the sector timing in the WAP is then determined (503). A virtual target beacon transmission time (TBTT) for the sector of interest serviced by the WAP is then calculated (506), as is a channel number of the sector of interest. Finally, the method provides for listening (507) for a sector beacon signal from the sector of interest at the virtual TBTT and the calculated channel number.

摘要： A method for performing neighbor discovery in a multi-tier wireless local area network where a client creates a neighbor list identifying a neighbor wherein the neighbor is identified as an access point or a client. Then, the client determines a time to perform a scan of neighbors based upon 1) a type of neighbor discovery to be performed and 2) when a first beacon is transmitted by an access point in a first tier of the multi-tier wireless local area network. Subsequently, the client performs a scan of neighbors at the determined time on a channel associated with the type of neighbor discovery. Finally, the client receives a beacon sent from a neighbor of the client to update the neighbor list with information transmitted in the beacon.

摘要： Methods for performing client to client communication in a wireless local area network are disclosed. At an ‘n’ tier client in the wireless local area network, a signaling message from an ‘n−1’ tier client is received wherein the signaling message comprises a first period, a second period, and a third period. Communicating with the ‘n−1’ tier client during the first period and communicating with the ‘n+1’ tier client during the third period. At an access point in the wireless local area network, an association table identifying clients in the wireless local area network is created and a first period for client to client communication based upon the association table and traffic in the wireless local area network is determined where the access point does not communicate with the clients during the first period.

摘要： A method for transmitting beacon transmissions in a wireless local area network (WLAN) communications system (100) operating on one or more channels includes transmitting a first beacon (C1) using a directional antenna in a first direction (D1) on a first channel. A second beacon (C2) is then transmitted using a directional antenna in a second direction (D2) on the first channel. This process is then repeated such that the first beacon and second beacon after a predetermined beacon interval. The first beacon begins its transmission at a target beacon transmission time (TBTT) and the second beacon begins its transmission in a sequential period defined by an antenna switching time after the transmission of the first beacon.
