Survey of Blackhole attack on MANET

摘要

Mobile Ad-Hoc Network (MANET) is a type of network where an aggregation of mobile devices communicating together wirelessly without the use of access point or router. This kind of networks are growing fast recently due to the growth in mobile users and its usage in many applications such as Vehicle Ad-Hoc Network (VANET), Flying Ad-Hoc Network (FANET), military, the rescue operations and much more. However, the security issue in MANET is still weak and need to be improved. There are many types of attacks targeted to MANET, but blackhole attack is one of the most harmful attacks among them. It happens when a malicious node declares that it got the best path to the destination, then it either discard or consumes the packet once it received. While there are many recent types of researches to prevent this kind of attack, they still got some limitations and it could not bring a final solution to stop the attacker, especially when there is more than one node. In this work, we are investigating the nature of blackhole attack in MANET in purpose to find an exhaustive algorithm to stop this kind of attack.
