P$5.$ Consider the $5-$bit generator, $G=10011,$ and suppose that $D$ has the value $1010101010.$P$19.$ Suppose nodes A and B are on the same $10Mbps$ broadcast channel, and the propagation

delay between the two nodes is $245$ bit times. Suppose A and B send Ethernet frames at the

same time, the frames collide, and then A and $B$ choose different values of $K$ in the CSMA$/$CD

algorithm. Assuming no other nodes are active, can the retransmissions from A and $B$ collide?

For our purposes, it suffices to work out the following example. Suppose A and B begin

transmission at $t=0$ bit times. They both detect collisions at $t=245t$ bit times. Suppose $KA=0$ and

$KB=1.$ At what time does $B$ schedule its retransmission? At what time does A begin

transmission? $($Note: The nodes must wait for an idle channel after returning to Step $2-$see

protocol.$)$ At what time does A$\text{'}$s signal reach B$?$ Does B refrain from transmitting at its

scheduled time?

What is the value of $R?$
