A wireless ad-hoc network is a temporary network set up by wireless nodes usually moving randomly and communicating without a network infrastructure. Due to security vulnerabilities of the routing protocols, however, wireless ad-hoc networks may be unprotected against attacks by the malicious nodes. In this paper, the authors investigated the effects of Black Hole attacks on the reactive and proactive MANET protocols, namely AODV and OLSR. Wireless ad-hoc networks are composed of autonomous nodes that are self-managed without any infrastructure. They usually have a dynamic topology such that nodes can easily join or leave the network at any time and they move around freely which gives them the name Mobile Ad hoc networks or MANETs.
