The HAMA/MINCAP subnetwork architecture was demonstrated in an Advanced Technology Demonstration (ATD) in September 1990. The following subnetwork protocols were included: the Hand-off Assigned Multiple Access (HAMA) channel access protocol, the Minimum Cover Approximation (MINCAP) broadcast routing protocol, and the Backwards Learning (BL) point-to-point routing protocol. HAMA is an adaptive Time Division Multiple Access based protocol. HAMA allows a node to temporarily hand-off a time slot to a neighbor with higher priority traffic. MINCAP uses a two hop connectivity matrix and a message history table to select relays. The three or fewer nodes which provide the best coverage of nodes who have not yet received the packet are designated as relays. BL uses a table containing delay information to each node in the network via the various relays available. The relay with the minimum path length is selected.
