Many-to-many communication techniques for mobile devices

A method of many-to-many communication techniques performed by a first mobile device, the method comprising:

• storing a schedule specifying a transmission time for transmitting ranging packets;
• designating a number of response timeslots for receiving a response from two or more participating mobile devices during the number of response timeslots;
• transmitting advertising packets comprising device information for the first mobile device via a first wireless protocol at an interval;
• transmitting ranging packets via a second wireless protocol according to the schedule;
• receiving two or more responses from the two or more participating mobile devices during the response timeslots via the second wireless protocol, the two or more responses comprising information from the two or more participating mobile devices from responding mobile devices;
• determining a number of the responding mobile devices based at least in part on a number of responses received from the two or more responding mobile devices, the two or more responding devices are configured to perform similar communication steps as the first mobile device;
• receiving two or more advertising packets transmitted from the responding mobile devices via the first wireless protocol;
• transmitting a response to the responding mobile devices via the second wireless protocol;
• determining a number of symmetrical communication links established between the responding mobile devices via the second wireless protocol, wherein a symmetrical communication link is between the first mobile device and one of the responding mobile devices;
• determining one or more redundant communication links of the symmetrical communication links established between the responding mobile devices, wherein a redundant communication link comprises a second symmetrical communication link between the first mobile device and the one of the responding mobile devices;
• and
• terminating one of the one or more redundant communication links established between the first mobile device and one of the responding mobile devices in coordination the one of the responding mobile devices.

A non-transitory computer-readable medium storing a plurality of instructions that, when executed by one or more processors of a group of mobile devices of N mobile devices that includes other mobile devices, N being an integer of three or more, cause the one or more processors to perform operations comprising:

• transmitting, via a first wireless protocol, a request to establish outgoing pairwise ranging sessions with other mobile devices of the group of mobile devices, the pairwise ranging sessions using a second wireless protocol;
• receiving, via the first wireless protocol from each of the other mobile device in the group of mobile devices, a request to establish an incoming pairwise ranging session with the other mobile device;
• detecting one or more redundant ranging sessions;
• identifying whether to keep or terminate each of the one or more redundant ranging sessions based on a criterion;
• and
• performing ranging using remaining ranging sessions with each of the other mobile devices.
