In Wireless ad-hoc network, the infrastructure of MANET's differ to each other due to the topology of
MANETs changes time to time because the mobile nodes of MANET's are movable. In MANETs protocols, if
any node wants to communicate with another node then they establish a path with the help of adjacent node
due to this the security in MANETs protocol is vulnerable. Thus, there are various types of attacks are try to
break the security of MANETs protocol. AODV is a popular and most usable protocol of MANET and Black
Hole Attack is a severe attack that affects the functionality of AODV protocol. The malicious node treat to the
source node which have freshest and nearest path for the destination.
In this work, my prime focus specifically is on follow the security against Black Hole Attack. I proposed
AODV protocol capture some extra effort for source node and destination node which based on best possible
effort (heuristic) with appropriate simulation using ns-2.35.
