Demand-Driven Prioritized Data Structure

A tangible computer readable medium having instructions stored thereon, the instructions configured to cause a device to perform operations comprising:

• mapping one or more data units stored in a first node to a first digest, wherein the plurality of radio nodes comprise the first node and one or more second nodes;
• broadcasting the first digest to at least one node of the one or more second nodes;
• comparing the first digest to at least one second digest from at least one node of the one or more second nodes to determine significance weighting factors for the one or more data units;
• and
• broadcasting at least one of the one or more data units to at least one of the one or more second nodes according to a schedule of significance factors based at least in part upon the significance weighting factors and connectivity among the plurality of radio nodes.

A radio node comprising:

• a memory;
• a communication device;
• a processing device, in communication with the memory and the communication device, configured to:
• map one or more data units stored in the memory to a local digest;
• broadcast the local digest using the communication device to at least one node in a plurality of radio nodes, the plurality of radio nodes comprising the radio node and one or more second radio nodes;
• receive a remote digest from at least one node of the one or more second radio nodes using the communication device;
• compare the remote digest and the local digest to determine significance weighting factors for the one or more data units;
• and
• broadcast at least one of the one or more data units using the communication device to at least one node of the second radio nodes according to a schedule of significance factors based at least in part upon the significance weighting factors and connectivity among the plurality of radio nodes.
