Abstract: Consider a lossy packet network of queues, communicating over a wirelessmedium. This paper presents a throughput-optimal transmission strategy for aunicast network when feedback is available, which has the following advantages:It requires a very limited form of acknowledgment feedback. It is completelydistributed, and independent of the network topology. Finally, communication atthe information theoretic cut-set rate requires no network coding and norateless coding on the packets. This simple strategy consists of each noderandomly choosing a packet from its buffer to transmit at each opportunity.However, the packet is only deleted from a node-s buffer once it has beensuccessfully received by the final destination
