Description: Reliable communication is mission critical to Emergency and Rescue operations.
MANET technology allowing communication where fixed infrastructure is not available
is very attractive for this setting. Emergency and Rescue operations may take place in
both hostile as well as benign environment. The communication system must handle
both situations. Security attacks can be launched towards any layer of the protocol
stack. What is new with wireless ad hoc networks is the network layer routing
information as a more probable target for security attacks. A reliable network service
cannot be provided without embracing routing information security. The primary
challenge is to decide which routing information can be trusted. The answer so far is
cryptographically signed routing messages. The possession of cryptographic keys serves
as proof of trustworthiness. A proper key management service is thus a critical factor
for the success of wireless ad hoc networks. Platform: |

Description: 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.
