    Abstract: Methods, devices, and computer program products for synchronization of wireless devices in a peer-to-peer network are described herein. In one aspect, a method for synchronizing a wireless communication apparatus is provided. The method includes receiving one or more synchronization messages, each synchronization message having timing information and a cluster identifier, the timing information comprising anchor timing information, the cluster identifier being the same value as a cluster identifier of the apparatus. The method further includes determining whether a difference between a time value when a received synchronization message last received anchor timing information and a time value maintained for the apparatus is greater than a threshold. The method further includes discarding the received synchronization message if the difference exceeds the threshold.

    Abstract: Methods, devices, and computer program products for collision management of wireless devices in a peer-to-peer network are described herein. In one aspect, a method of communicating via a wireless medium by a wireless communications apparatus within a neighborhood aware network is provided. The network is configured with periodic discovery windows, and sized for a maximum number of devices M. The method includes determining a discovery window interval K, the smallest integer greater than or equal to one, such that the probability that more than a threshold M devices will transmit during the same discovery window is less than a threshold probability P. The method further includes selecting a random or pseudo-random integer m in the range from 0 to K−1, deferring for at least m discovery windows after a previous interval K−1 has elapsed, and transmitting a discovery frame during the next discovery window after said deferring.

    Abstract: Methods, systems, and devices are described for power conservation in a wireless communications system through efficient transmissions and acknowledgements of information between an AP and a station. The time between a determination by a station to enter a power saving mode and entering network sleep mode by the station may be reduced through a transmission, by an AP, of an MPDU to the station successive to an SIFS after transmission of an acknowledgement to the station of a PS-Poll frame from the station. The time to enter a power saving mode by a station may also be reduced through transmission of A-MPDUs in which a last MPDU of the A-MPDU has an indicator bit cleared to indicate no additional data is to be transmitted. An AP may prevent a retransmission of an MPDU to the station in the absence of an acknowledgement from the station, to further enhance efficiency.

    Abstract: Methods, devices, and computer program products for collision management of wireless devices in a peer-to-peer network are described herein. In one aspect, a method of communicating via a wireless medium by a wireless communications apparatus within a network is provided. The method includes determining first and second contention windows. The first contention window begins earlier than the second contention window. The method further includes beginning a first carrier sense multiple access (CSMA) countdown at the start of the first contention window. The method further includes beginning a second CSMA countdown when the first CSMA countdown does not end before the start of the second contention window. The method further includes transmitting the prepared frame at a time of the first CSMA countdown ending or the second CSMA countdown ending, whichever is earlier.

    Abstract: Systems and methods for monitoring the number of neighboring wireless devices in a wireless network are described herein. In one aspect, the method includes receiving a message from one of the neighboring wireless devices having an identifier associated with the neighboring wireless device and adding the identifier into a Bloom filter. The method may further include estimating the number of distinct strings that have been added into the Bloom filter based on the number of zeros in the Bloom filter, the number of distinct strings representing an estimate of the number of neighboring wireless devices in the wireless network.
