One of several attacks that occur in the MANET network are black hole and gray hole attacks. Black hole attack is an attack that causes packets around the attacker's node to be lost so that network is at a loss and gray hole attack transmit the packets in inappropriate director or routes. Choosing the right routing protocol is one of the efforts to minimize the impact of black hole attacks. This research was made to enhance the behaviour of AODV routing protocols in minimize the impact of black hole and grey hole attacks. The results of this scheme indicate that proposed AAODV is better than AODV from several qualities of service values such as throughput, delay and packet loss Key words: Security, Blackhole Attack, Grayhole Attack, AODV, MANET Cite this Article: Anu Sharma and Jitendra Sheetlani, Recognition and Avoidance of Blackhole and Grayhole Attacks in Manet Using Novel Augmented Ad Hoc on Demand Distance Vector (AAODV), International Journal of Management (IJM), 11(8), 2020, pp. 2216-2228. http://www.iaeme.com/IJM/issues.asp?JType=IJM&VType=11&IType=8 1.
