A Basic Understanding of Routing Protocols for Mobile Ad-Hoc Network with a Security Threat: Black Hole Attack
The black hole problem is one of the security attacks that occur in Mobile Ad-hoc NETworks (MANETs). The intruders utilize the loophole to carry out their malicious behaviors because the route discovery process is necessary and inevitable. Mobile ad-hoc networks are autonomous and decentralized wireless systems. It consists of mobile nodes that are free in moving in and out in the network. Many routing protocols have been developed for MANETS, i.e. AODV, OLSR, DSR etc. Security in mobile ad-hoc network is the most important concern for the basic functionality of network.
