A group communication system arrangement is provided. The group communication system arrangement includes a configuration of nodes, which are uniquely identified by corresponding identifiers (ID). The nodes are mutually coupled in communication, and are operable to exchange data amongst themselves. Further, the nodes are grouped into proximity segments, depending upon communication characteristics between the nodes. A node of a given second proximity segment of the proximity segments is selected for receiving data to be synchronized. The node of the given second proximity segment is selected based upon an ID of a node of a given first proximity segment of the proximity segments, which is operable to send the data to the node of the given second proximity segment.
