This study has evaluated four ad-hoc routing protocols in different
network environment taking into consideration node mobility.
Overall, the findings show that the energy consumption and
throughput in small size networks did not reveal any significant
differences. However, for medium and large ad-hoc networks the
TORA performance proved to be inefficient in this study. In particular,
the performance of AODV, DSDV and DSR in small size
networks was comparable. But in medium and large size networks,
the AODV and DSR produced good results and the performance
of AODV in terms of throughput is good in all the scenarios that
have been investigated.
Whilst experimenting with TORA in ns2, TORA seems to
be providing poor performance which is very controversial to the
theoretical expectations. Finding the reason for this poor behaviours’
and correcting it is not simple. It is more than complex that
