A method and apparatus includes a communication device monitoring for an indication of presence with respect to the communication device. The method involves transmitting, when detecting the indication of presence, a first series of neighborhood awareness networking discovery beacon frames having a first interframe time interval. The method further involves transmitting, when not detecting the indication of presence, a second series of neighborhood awareness networking discovery beacon frames having a second interframe time interval that is longer than the first interframe time interval.

Method and apparatus for discovering neighborhood awareness networking devices based on presence

A first communication device performs a method that includes detecting a common network connection with a second communication device. The method further includes determining to perform neighborhood awareness networking scanning on behalf of the second communication device. When the first communication device detects a neighborhood awareness networking transmission while performing the neighborhood awareness networking scanning, it notifies the second communication device and discontinues the scanning on behalf of the second communication device.

Method and apparatus for discovering neighborhood awareness networking devices using a surrogate device

A device and method for determining a master device in a neighborhood aware network (NAN). The method includes identifying a number of peer devices located within communication range of a first device and that are capable of communicating via the NAN. A master rank value associated with a corresponding peer device is retrieved from each received response. A first master rank value is calculated for the first device, at least partially based on the number of responding peer devices. The first master rank value is compared with the received master rank values of the responding peer devices. In response to the first master rank value being greater than each of the received master rank values, the first device assumes a role of a master device within a NAN cluster that includes the first device and the responding peer devices.

System and method for determining a master device in a neighborhood aware network

A method and apparatus includes a NAN communication device suppressing NAN scanning and scanning using an alternate scanning protocol while suppressing NAN scanning. The method additionally includes detecting a transmission from another communication device while scanning using the alternate scanning protocol and determining the detected transmission is a NAN transmission. The method further includes discontinuing suppressing NAN scanning in response to detecting the NAN transmission.

Disclosed are peer-to-peer group re-formation techniques. The techniques enable automatic reformation of a peer-to-peer group when the Group Owner ('GO') device is lost. To do so, the techniques enable selection of a one of the peer devices in the peer-to-peer group as a next GO device responsive to detecting the loss of the original GO device. Then, the peer device selected as the next GO device automatically activates as the GO device, while the other peer devices scan for and connect to the next GO device.

Peer-to-peer group re-formation

The present invention provides a system and method for managing secure communications in an ad-hoc network having three or more users including a first user, a second user and a third user. Each user is associated with at least one communication device, and has a set of keys associated with the user for managing secure communications between the at least one communication device of the user and the at least one communication device of another one of the three or more users. Each set of keys includes a private key and a public key, where the public key is shared with the communication device of the other ones of the three or more users with which the user has been authenticated, and the private key is used to decrypt communications encrypted using the corresponding public key from the same set of keys. When the second user of the three or more users has been authenticated by the first user, in addition to receiving the associated public key of the second user, the first user receives a value defining a share authority level, which defines the authority of the first user relative to the second user to provide peer key sharing with the third user.

System and method for managing secure communications in an Ad-Hoc network

A phone call is made from an initiator phone to a receiver phone (). The receiver phone determines how many people are near the receiver phone, and generates a response based on how many people are near the receiver phone. This response can be, for example, a message that is sent to the initiator phone and can be displayed at the initiator phone, indicating either that no one is near the receiver phone or that multiple people are near the receiver phone. The number of people that are near the receiver phone is monitored, and when just one person near the receiver phone is detected, various different actions can be taken. A message can be sent for display at the initiator phone indicating that there is only one person near the receiver phone, or the receiver phone can prompt the user to call back the initiator phone.

Phone call management based on presence of nearby people

A method, device, system, or article of manufacture is provided for low-power management of multiple sensor chip architecture. In one embodiment, a method comprises, at a computing device that includes a first processor, a second processor and a third processor, receiving, by the first processor operating at a first clock rate, first sensor data from a first sensor operating at a first data rate; determining, by the first processor, a movement of the computing device using the first sensor data; in response to determining the movement of the computing device, performing, by the first processor, a first motion state algorithm to determine whether a modality of the computing device is a first motion state; and, in response to determining that the modality of the computing device is not the first motion state, changing, by the first processor, at least one of the first processor to operate at a second clock rate sufficient to perform a second motion state algorithm and changing the first sensor to operate at a second data rate sufficient to perform the second motion state algorithm, wherein the second motion state algorithm is used to determine whether the modality of the computing device is a second motion state.
