... relay knows what destinations are waiting for the lost packets to be retransmitted and then decides how to combine and forward the data to the intended destinations. In the following, we introduce some ... at destinations using network coding. In the proposed ARQ protocol, the relay detects packets from different s ources and combines the lost packets using NC. In particular, two packet-...
