End To End Delay
Figure 4.27 shows the end to end delays as a function of group size. The bigger value of
delay the less efficient the protocol. In reality, SReM shows lower delay in comparison with
Xcast+. This is because scalability feature in SReM make the intermediate nodes to forward
the data packets faster where in Xcast+ the data packets will take high processing time in the
intermediate nodes which lastly will increase the delay for the data packets arrival at the end
nodes.
