Abstract:
Methods, devices, and computer program products communicating discovery information in a wireless neighborhood aware network (NAN). One method includes receiving a message from a neighboring wireless device. The message includes an identifier associated with the neighboring wireless device. The method further includes adding the identifier to a data structure indicative of discovered device identifiers. The method further includes transmitting a message including the data structure indicative of discovered device identifiers.
Abstract:
A device for communication includes a processor, a transmitter, and a receiver. The processor is configured to generate a traffic advertisement indicating availability of data to be sent to a plurality of devices. The traffic advertisement includes a unicast message addressed to a first device of the plurality of devices. The transmitter is configured to transmit the traffic advertisement during a paging window. The receiver is configured to receive, during a data transmission window that is subsequent to the paging window, a data request from a second device of the plurality of devices. The data request is responsive to the traffic advertisement. The transmitter is further configured to send first data to the second device responsive to the data request.
Abstract:
Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, an access point transmits a beacon to a station. The beacon comprises a Wi-Fi Protected Access II pre-sharked key (WPA2-PSK) authentication type. The access point further receives an authentication request from the station. The access point further transmits an authentication response to the station. The authentication response comprises the WPA2-PSK authentication type. The access point further retrieves a PSK and generates a PMK based on the PSK. The access point further receives an association request from the station after generation of the PMK. The association request comprises a key confirmation derived from the PSK. The access point further transmits an association response to the station in response to reception of the association request. The association response comprises the key confirmation.
Abstract:
Systems, methods, and devices for multicast wireless local area network messages with message authentication are contained herein. The method includes determining a message integrity check value for each of a plurality of wireless devices. The method further includes transmitting a multicast packet to each of the plurality of devices on a wireless local area network, the multicast packet including an indication of each of the plurality of devices and the message integrity check value for each of the plurality of devices.
Abstract:
Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a relay is configured to receive at least one first parameter advertised by a first potential parent relay and at least one second parameter advertised by a second potential parent relay. The relay may be further configured to select the first potential parent relay or the second potential parent relay to relay one or more packets based on the at least one first parameter advertised by the first potential parent relay and the at least one second parameter advertised by the second potential parent relay.
Abstract:
A method for arranging media access control protocol data units (MPDUs) includes generating a multi-destination aggregated media access control protocol data unit (MD-AMPDU) at an access point. The MD-AMPDU includes a first set of one or more MPDUs having a first receive address associated with a first station and a second set of one or more MPDUs having a second receive address associated with a second station. The first set of one or more MPDUs is grouped together in the MD-AMPDU and the second set of one or more MPDUs is grouped together in the MD-AMPDU. The method also includes transmitting the MD-AMPDU to the first station and to the second station via an Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless network.
Abstract:
A method includes determining, at a first transmitter, whether to permit reuse of a first transmit opportunity (TXOP) associated with a message. The method further includes sending a portion of the message from the first transmitter to a first receiver. The portion of the message indicates whether reuse, by a reuse transmitter, of the first TXOP is permitted. When reuse of the first TXOP is permitted, the reuse transmitter is permitted to send a second message while the first transmitter sends a second portion of the message to the first receiver during the first TXOP.
Abstract:
Methods, devices, and computer program products for synchronization of wireless devices in an ad-hoc network are described herein. In one aspect, a method for synchronizing a wireless communication apparatus is provided. The method includes generating, at a wireless communication apparatus, one or more messages identifying a second device to generate prospective synchronization messages. In some aspects, the second device is a back-up root device. The method further includes transmitting a synchronization message. In one aspect, a root device for an ad-hoc network is responsible for generating synchronization messages for nodes of the ad-hoc network. The root device also generates and transmits a message which identifies a back-up root device. The back-up root device may assume responsibility for generating synchronization messages for the ad-hoc network in the event that the wireless communication apparatus no longer generates synchronization messages for the ad-hoc network. In an embodiment, the generated message identifying the back-up root device is included in a synchronization message.
Abstract:
Methods, systems, and devices related to wireless communication via a mesh network are described. In particular, the disclosure is directed to selecting a path between two nodes in a wireless mesh network based on consideration of type of data requested and a determination whether an intermediate node, within a predetermined range of the requesting node, is actively broadcasting the requested data. Such opportunistic consideration in selecting a path between two nodes may avoid unnecessary activation of additional broadcasting nodes and reduce the risk of triggering interference between multiple nodes broadcasting duplicate data.
Abstract:
A method of communication includes generating, at a first device, a traffic advertisement indicating availability of data to be sent by the first device to at least one second device. The method also includes sending the traffic advertisement during an initial portion of a neighbor aware network (NAN) data link (NDL) time block. The method further includes sending first data to the second device during the NDL time block. The first data is sent independently of receiving an acknowledgement (ACK) responsive to the traffic advertisement from the second device.
