Performance Analysis of ARQ Protocols
📊 Performance of ARQ Protocols ARQ protocols are central to ensuring reliable data transmission, but their performance can vary based on factors like channel quality, window size, and protocol type. Let’s dive into the performance evaluation of Stop-and-Wait, Go-back-N, and Selective Repeat. 📈 Stop-and-Wait ARQ Efficiency: In Stop-and-Wait ARQ, the sender must wait for an acknowledgment after sending a frame, which leads to poor utilization of available bandwidth, especially in high-latency networks. Throughput: [ \text{Throughput} = \frac{\text{Frame Size}}{\text{Transmission Time} + \text{Round-Trip Time (RTT)}} ] Where RTT represents the time for a packet to go to the receiver and back. ...
