DVMRP being a distance vector routing protocol had the same shortcomings as those faced by unicast
distance vector protocols such as Routing Information Protocol (RIP), where the hop count limited the protocols to be used only in smaller networks.
The Secure Efficient Ad hoc
Distance vector protocol SEAD (by Hu, Johnson and Perrig [7]).
Among the three types of routing protocols, the simplest to configure is the
distance vector protocol which use the distance and direction to find the best path to the destination by using an algorithm called the Bellman-Ford algorithm [13].
Destination sequenced
distance vector protocol (DSDV) is selected as an example for table-driven protocols, while both dynamic source routing (DSR) and ad hoc on-demand distance vector (AODV) protocols are selected as examples for on-demand protocols [19-21].
Traditional protocols similar link state and
distance vector protocols are improved to create on demand routing algorithm.
