Arq May 2026

ARQ increases latency due to retransmissions, making it less suitable for real-time applications like VoIP.

The sender transmits one frame and waits for an ACK before sending the next. Pros: Simple implementation. ARQ increases latency due to retransmissions, making it

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

The receiver sends an ACK to confirm the successful receipt of a packet. ARQ increases latency due to retransmissions, making it

Higher bandwidth–delay products require larger window sizes (GBN/SR) to maintain high throughput. 5. Hybrid ARQ (HARQ)
