Wireless Ad-hoc Network Under Black-Hole Attack
Wireless Ad-hoc Network is a temporary and decentralized type of wireless network. Due to security vulnerabilities in the routing protocol currently, this type of network is unprotected to network layer attacks. Black-hole attack is such a type of attack and is a Denial-of-Service (DoS) attack. Due to its nature, the attack makes the source node send all the data packets to a Black-hole node that ends up dropping all the packets. The aim of this paper is to reflect light on the severe effects of a Black-hole attack in a Wireless Ad-hoc network and the drawbacks of the security mechanisms being used for the mitigation of this attack.
