The sender has to keep waiting for acknowledgements before sending the processed next packet.

After all of the data frames have been sent, the master can send a stop condition to the slave to halt the transmission. Characteristics of Stop and Wait ARQ: It uses a link between sender and receiver as a half-duplex link Throughput 1 Data packet/frame per RTT If the BandwidthDelay product is very high, then they stop and wait for protocol if it is not so useful. Int rw // tells expected frame public: void input() SIMULATE SELECTIVE REPEAT PROTOCOL # include # include # include # include # include # define TOT_FRAMES 500 # define FRAMES_SEND 10 class sel_repeat Stop and Wait used ARQ mainly implements the Sliding Window Protocol concept with Window Size 1 Useful Footing: Propagation Delay: Amount of time picked by a pack to make a physical journey from one router toward another router.
