The delay is affected by high rate of CBR packets as well.
The buffers become full much quicker, so the packets have
to stay in the buffers a much longer period of time before
they are sent. This can be seen at the DSR routing protocol
when it was reach around 2400 packets at the 0 mobility.
For average end-to-end delay, the performance of DSR and
AODV are almost uniform. However, the performance of
DSDV is degrading due to increase in the number of nodes
the load of exchange of routing tables becomes high and
the frequency of exchange also increases due to the mobility
of nodes.
