ABRD: Acknowledgement Based Route Discovery and Detection of Black-Hole Attack in MANET
Kareemullah Shaik · 2015
2 Abstract: Mobile Ad hoc Network (MANET) is a collection of many autonomous nodes, these nodes of MANET's acts as a node and router. These networks are also known as infra-structure less networks. In real time MANET's are being used in applications such as disaster relief, Military, emergency operations, vehicular communication, campus networks and so on. Because of open medium, limited bandwidth, dynamic topology, limited battery power and lack of central authority MANET's are very much vulnerable to various types of security attacks in network. Attackers attack MANET at different layers of its protocol stack. Due to inefficient routing protocol these attacks are more at Network layer since there is no efficient routing protocol. In this paper we study the effect of black-hole attack on AODV routing protocol. Also we propose a mechanism known as secure route discovery to discover valid and secure path between source and destination using acknowledgement based technique, this mechanism will easily detect malicious nodes and defend the black- hole attack in mantes.
