Analysis of Black Hole Effect and Prevention through IDS in MANET
Simranjit Kaur, Sandeep Kumar Arora · 2013
A mobile ad hoc network (MANET) is an autonomous network. It is a collection of mobile nodes that communicate with each other over wireless links. From last few years, the interest in the area of Mobile Ad- hoc Network (MANET) is growing due to its practical applications and requirement of communication in mobile devices. In the comparison to wired or infrastructure-based wireless network, MANET is vulnerable to security attacks due to its fundamental characteristics, e.g., the open medium, dynamic network topology, lack of clear lines of defense, autonomous terminal, lack of centralized monitoring and management. There are various types of attacks in MANET which drops the network performance. Black hole attack is one of them. Ad hoc On-demand Distance Vector routing (AODV) is a popular routing algorithm MANET. In this paper we investigated the effects of Black Hole attacks on the network performance. In our work we simulated black hole attacks in Network Simulator 2 (ns-2) and measured the throughput, PDF and routing load in the network with and without a black hole. We also proposed a solution against black hole attacks using intrusion detection system (IDS).
