        scanf("%d",&frames[i]);

 

    printf("\nWith sliding window protocol the frames will be sent in the following manner (assuming no corruption of frames)\n\n");

            printf("%d\n",frames[i]);

            printf("Acknowledgement of above frames sent is received by sender\n\n");

        }

    if(f%w!=0)

        printf("\nAcknowledgement of above frames sent is received by sender\n");

}

 

Output

Enter window size: 3

Enter number of frames to transmit: 5

Enter 5 frames: 12 5 89 4 6

With sliding window protocol the frames will be sent in the following manner (assuming no corruption of frames)

After sending 3 frames at each stage sender waits for acknowledgement sent by the receiver

12 5 89
Acknowledgement of above frames sent is received by sender

4 6
Acknowledgement of above frames sent is received by sender
