摘要： The present invention relates to a system and method for proportional-fair resource allocation for multi-rate random access. The method includes receiving, by a device, data packets to be transmitted to an access point on a shared uplink channel, and determining, by the device, whether or not to contend for access to the shared uplink channel based on a probability of access. The probability of access is based on a data transmission rate between the device and the access point.

摘要： QoS aware multi radio access point for operation in TV whitespaces is disclosed. The present invention relates to operation of access points and, particularly, to operation of access points in TV whitespaces. The AP is configured to intelligently choose the radios, determine available whitespaces in the spectrum and allocate radios to the available whitespaces in the spectrum. The method determines clients that need to be serviced by the AP and assigns each client associated with AP to one of the radios. In addition, the method also takes care of QoS requirements for different services and hence every service is addressed to satisfy its QoS requirements. The method ensures that there is maximum utilization of available whitespace spectrum by accounting for the spectrum specific characteristics. The method considers bands for operation are spread across the spectrum and allocates the clients based on the availability of bands throughout the spectrum.

摘要： Systems and methods for beaconing and management in bandwidth adaptive wireless networks are disclosed. The present invention relates to bandwidth allocation for access points and, more particularly, to bandwidth allocation for access points in wireless networks. The method employs mechanisms for beaconing and management to associate clients with Access Point (AP). The beaconing mechanism allows the client to discover part of the spectrum over which an AP operates efficiently. Periodic beacon messages are sent by AP to the client over the bandwidth of operation of the channel. The client then sends a client association request and gets associated with the AP. Further, critical information is conveyed to the AP in the beacon message. The AP further allocates the client to one of its radios of operation. The system is configured to handle disruptions and switching the AP to different parts of the spectrum during such disruptions.

摘要： Disclosed is a method and apparatus for allocating a whitespace spectrum associated with a plurality of access points. The method includes reporting a signal strength associated with each of a plurality of other access points to a central controller. The method includes aggregating a plurality of demands to produce an aggregate demand. Each of the plurality of demands is associated with one of a plurality of users. The method includes reporting the aggregated demand to the central controller. The method includes associating one of the plurality of users with the access point based on a user setting or associating one of the plurality of users based on an allocation by the central controller. The allocation from the central controller is based on the signal strength and the aggregated demand. The allocation indicates a frequency band from the set of frequency bands to be allocated by the access point to the user.
