Identifying a synchronization master for radio nodes

A non-transitory computer-readable storage medium for use in conjunction with a computer, the computer-readable storage medium storing program instructions that, when executed by the computer, provide second information by causing the computer to perform one or more operations comprising:

• receiving information associated with one or more candidate radio nodes in a cluster of radio nodes, wherein the information associated with a given candidate radio node in the one or more candidate radio nodes specifies that the given candidate radio node meets one or more synchronization master criteria and the information comprises one or more performance metrics corresponding to satellite signals or wireless signals, wherein the satellite signals are associated with a global positioning system and the wireless signals that are associated with a cellular-telephone network;
• selecting, based at least in part on the one or more performance metrics of the one or more candidate radio nodes and network information, a radio node in the one or more candidate radio nodes as a synchronization master for at least a subset of the radio nodes in a remainder of the radio nodes in the cluster of radio nodes, wherein the remainder of the radio nodes do not meet the one or more synchronization criteria;
• and
• providing, addressed to at least the subset of the radio nodes, the second information specifying the radio node as the synchronization master, wherein the second information comprises a network address of the synchronization master, and
• wherein the computer does not provide, to the radio node, identifiers of at least the subset of the radio nodes.

A method for providing second information, comprising:

• by a computer:
• receiving information associated with one or more candidate radio nodes in a cluster of radio nodes, wherein the information associated with a given candidate radio node in the one or more candidate radio nodes specifies that the given candidate radio node meets one or more synchronization master criteria and the information comprises one or more performance metrics corresponding to satellite signals or wireless signals, wherein the satellite signals are associated with a global positioning system and the wireless signals are associated with a cellular-telephone network;
• selecting, based at least in part on the one or more performance metrics of the one or more candidate radio nodes and network information, a radio node in the one or more candidate radio nodes as a synchronization master for at least a subset of the radio nodes in a remainder of the radio nodes in the cluster of radio nodes, wherein the remainder of the radio nodes do not meet the one or more synchronization criteria;
• and
• providing, addressed to at least the subset of the radio nodes, the second information specifying the radio node as the synchronization master, wherein the second information comprises a network address of the synchronization master, and
• wherein the computer does not does not provide, to the radio node, identifiers of at least the subset of the radio nodes.
