摘要:
Computer systems and methods for generating a social network of users based on the users' devices being operably coupled are discussed herein. Specifically, techniques are described herein to determine the types of relationships between a plurality of users based on telemetry data collected at one or more server computers from the users' operably coupled client devices. The telemetry data describes, among other things, protocol(s) and network interface(s) used to operably couple the client devices, network operations performed by the client devices, and sensory data recorded by the client devices while the devices are operably coupled.
摘要:
Apparatus and method are provided for discovery and networking of proximate devices using acoustic messaging. In one novel aspect, a peer discovery protocol is used to discover proximate devices using voting messages encoded in ultrasonic waveform. In one embodiment, the UE receives one or more voting messages from neighboring UEs encoded in ultrasonic waveform, builds its voting message and broadcasts the voting message encoded in ultrasonic waveform. In another embodiment, based on the voting result, a multi-tier wireless LAN is established by the master UEs through two RF interfaces. In another novel aspect, an optimized synchronization by the receiver is used to locate the transmitted frame boundary of the ultrasonic message. In one embodiment, the UE reversed-looks up a pre-calculated boundary-offset table to estimate the tone boundary and searches the maximum synchronization tone energy down to per sampling interval using a predefined search algorithm to optimize locating the tone boundary.
