Master-less device coordination in location positioning system

A method, comprising:

• receiving, at a first communication device of a plurality of communication devices, at least one message from a second communication device of the plurality of communication devices over a preconfigured time duration, the second communication device broadcasting a subsequent message to the at least one message at a time interval based on remaining battery power;
• determining, at the first communication device, a first local time of a clock of the first communication device at which the at least one message from the second communication device is received;
• determining, at the first communication device, a sync-time of the second communication device based on the at least one message from the second communication device;
• mapping, at the first communication device, the sync-time of the second communication device to a second local time of the clock of the first communication device based on the first local time, and the determined sync-time of the second communication device;
• adjusting, at the first communication device, a sync-time of the first communication device based on the second local time;
• and
• transmitting a first data or a second data as an acoustic signal for location positioning,
• wherein the sync-time of the first communication device corresponds with a first configurable offset within which the first data is transmitted from the first communication device to the plurality of communication devices, and
• wherein the sync-time of the second communication device corresponds with a second configurable offset within which the second data is transmitted from the second communication device to the plurality of communication devices.

A non-transitory computer-readable medium (CRM) comprising computer instructions, where upon execution of the computer instructions by one or more processors of a communication device of a plurality of communication devices, cause the one or more processors to:

• receive at least one message from a second communication device of the plurality of communication devices over a preconfigured time duration, the second communication device broadcasting a subsequent message to the at least one message at a time interval based on remaining battery power;
• determine a first local time of a clock of the communication device at which the at least one message from the second communication device is received;
• determine a sync-time of the second communication device based on the at least one message from the second communication device;
• map the sync-time of the second communication device to a second local time of the clock of the communication device based on the first local time, and the determined sync-time of the second communication device;
• adjust a sync-time of the communication device based on the second local time;
• and
• transmit a first data or a second data as an acoustic signal for location positioning,
• wherein the sync-time of the communication device corresponds with a first configurable offset within which the first data that comprises location information of the communication device is transmitted from the communication device to the plurality of communication devices,
• wherein the sync-time of the second communication device corresponds with a second configurable offset within which the second data that comprises location information of the second communication device is transmitted from the second communication device to the plurality of communication devices, and
• wherein the communication device and the second communication device are base stations.
