The sender transmits one frame and waits for an ACK before sending the next. Pros: Simple implementation.
Low throughput on links with high propagation delay, as the channel remains idle while waiting for ACKs. 3.2. Go-Back-N ARQ (GBN)
ARQ increases latency due to retransmissions, making it less suitable for real-time applications like VoIP. The sender transmits one frame and waits for
combines traditional ARQ with Forward Error Correction (FEC) . The receiver attempts to correct small errors using error-correcting codes; if the error is too great, a retransmission is requested. This approach, specifically Type-II Hybrid ARQ , provides a more efficient approach in poor radio conditions, optimizing throughput. 6. Conclusion

Automatic Repeat Request (ARQ): Reliable Data Transmission 1. Introduction
Shahad, with over a decade as a fashion stylist and cyber shopper, knows firsthand the challenges of navigating endless fashion choices and how product discovery can be a painful experience. Frustrated by the impersonal nature of online shopping, she envisioned a solution that could serve as a personalized fashion assistant; one that truly understands each consumer’s unique preferences and brings the right SKUs to their fingertips. This vision led to the creation of TAFFI.
