It is difficult for the quantitative comparison of the most of
the ad hoc routing protocols due to the fact that simulations
have been done independent of one another using different
metrics and using different simulators. This paper does the
realistic comparison of three routing protocols DSDV,
AODV and DSR. The significant observation is, simulation
results agree with expected results based on theoretical
analysis. As expected, reactive routing protocol AODV
performance is the best considering its ability to maintain
connection by periodic exchange of information, which is
required for TCP, based traffic. AODV performs predictably.
Delivered virtually all packets at low node mobility, and
failing to converge as node mobility increases. Meanwhile
DSR was very good at all mobility rates and movement
speeds and DSDV performs almost as well as DSR, but still
requires the transmission of many routing overhead packets.
At higher rates of node mobility it’s actually more expensive
than DSR. Compared the On-Demand (DSR and AODV)
and Table-Driven (DSDV) routing protocols by varying the
number of nodes and measured the metrics like end-end
delay, dropped packets, As far as packet delay and dropped
packets ratio are concerned, DSR/AODV performs better
than DSDV with large number of nodes. Hence for real time
traffic AODV is preferred over DSR and DSDV. For less
number of nodes and less mobility, DSDV’s performance is
superior.
