The sender transmits one frame and waits for an ACK before sending the next. Pros: Simple implementation. equations) or a ? Do youg.
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. protocol efficiency calculations
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.
