Selective Message Rebroadcast for Tactical Radio Reliability

The patent implements a feedback mechanism where receivers send acknowledgment messages containing their current position in the message series to the transmitter. The transmitter uses this feedback to determine which messages need retransmission and sends only those specific messages, rather than all messages or using systematic acknowledgment protocols. This selective feedback approach maintains reliability while minimizing bandwidth consumption.

Instead of using full systematic acknowledgment mechanisms that acknowledge every packet, the patent uses partial acknowledgment where receivers only acknowledge their position in the series. The transmitter then performs partial retransmission of only the missing messages based on the weakest receiver's position, rather than retransmitting all messages or using excessive acknowledgment traffic.

The patent creates a universal communication protocol that works for both unicast and multicast/broadcast scenarios. The same message series mechanism, acknowledgment protocol, and selective retransmission logic are used regardless of whether the transmitter is sending to one receiver or multiple receivers. This makes the protocol adaptable to different communication modes while maintaining reliability through the series-based approach.

The patent segments the communication process into discrete message series with sequential identifiers. Each message contains its position in the series, allowing the protocol to handle both point-to-point and multicast scenarios by simply changing the target recipients while keeping the same reliability mechanisms. The segmentation into identifiable message units enables flexible adaptation to different communication topologies.
