An Adaptive Type-I1 hybrid ARQ/FEC Protocol - Clemson University

ARQ is an indispensable tool for achieving reliable digital communication. While Stop-and-Wait is efficient for simple, low-delay networks, Go-Back-N and Selective Repeat are essential for modern high-speed networks. The hybrid approach (HARQ) offers the best balance of efficiency and reliability in modern wireless scenarios.

The choice of ARQ protocol involves trade-offs between complexity and efficiency:

The receiver sends an ACK to confirm the successful receipt of a packet. The sender can transmit multiple frames (within a

If the sender does not receive an ACK within a designated time (timeout) or receives a NAK, it retransmits the packet. 3. Types of ARQ Protocols 3.1. Stop-and-Wait ARQ
