The feature of VANET mostly resembles the operation technology of MANET in the sense that
the process of self-organization, self-management, low bandwidth and shared radio
transmission criteria remain same. But the key hindrance in operation of VANET comes from the
high speed and uncertain mobility [in contrast to MANET] of the mobile nodes (vehicles) along
the paths. This suggested that the design of efficient routing protocol demands upgradation of
MANET architecture to accommodate the fast mobility of the VANET nodes in an efficient
manner. This warranted various research challenges to design appropriate routing protocol. It is
therefore important at this stage to reiterate the key characteristics of VANET that may be
accounted for the design of various routing protocols.
