Stop and Wait ARQ is less used because of its low efficiency. For anyone wonder why I don't use TCP. The sliding window protocol is used where reliable in-order delivery of packets is required. Therefore, maximum window size possible of sender and receiver = 2 n-1. In this protocol, the sender transmits a single data frame and waits for an acknowledgment from the receiver before sending the next frame. To avoid this, Selective Repeat ARQ can be used. Because of this reason first run the receiver program and afterwards run the sender program. In the stop-and-wait protocol, the sender can send only one frame at a time and cannot send the next frame without receiving the acknowledgment of the previously sent frame, whereas, in the case of sliding window protocol, the multiple frames can be sent at a time. ARQ is an error-control strategy used in a two-way communication system. Thus it uses the concept of stop and waits for the protocol. The receiver side sends only independent acknowledgements when it successfully receives packets from the sender instead of You signed in with another tab or window. This project aims to streamline the onboarding process for Irrespective of the number of packets sender is having stop and wait for protocol requires only 2 sequence numbers 0 and 1; Constraints in Stop and Wait ARQ. C++ Programming . Selective Repeat and Stop and Wait ARQ are similar in terms of retransmissions.
