Algorithm 3 Scheduling algorithm of sending time

X.starttime = 0

//node(i).starttime is the time that node(i) begin to send

X.endtime = X.starttime +X.pl× 0.17+X.delay

//node(i).pl is the data packet length of node(i)

//node(i).delay is the propagation delay to the receiving node

for $i=1:N$

if $X.endtime<node\left(i\right).starttime$

break

else

X.starttime = node(i).endtime-X.pl*0.17+X.delay

X.endtime =X.starttime+X.pl*0.17+X.delay

end if

end for
