چکیده

A mobile adhoc network (MANET) is an infrastructure-less type network, which consists of number of mobile nodes with wireless network interfaces. In MANET every node can functions as transmitter, router and data sink. MANET has dynamic topology which allows nodes to join and leave the network at any point of time. MANET is more vulnerable due to its characteristics such as dynamic topology, distributed cooperation and open medium. Security issues in mobile adhoc networks are veiled by various techniques that were introduced in past decade. Due to decentralized nature of MANET, the security issues cultivate resulting in welcoming various lethal vulnerabilities. Out of all attacks in MANET, Black hole attacks are considered most challenging adversarial modules that tremendously affect the communication system in MANET. This paper presents survey of various security techniques used for mitigating Black hole attacks in MANET.

A Survey of Solutions to Protect Against All Types of Attacks in Mobile Ad Hoc Networks

In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

An Analysis and Prevention of Routing Attacks in Mobile Adhoc Networks

In Mobile Adhoc Networks (MANETs), routing attacks are considered as a serious issue. However, in the presence of malicious nodes, the networks are affected by various kinds of attacks. The malicious node(s) can attack a MANET in different ways, such as sending fake messages several times; fake routing information and advertising fake links to disrupt routing operations. Black hole attacks are ...

DOS Attack Severity on Static and Mobile Adhoc Network

A wireless ad-hoc network is a collection of autonomous nodes that communicate with each other by each node acting as router and maintaining connectivity in a decentralized manner. The network topology is dynamic because the connectivity among the nodes may vary with time due to node departure, new arrivals and the possibility of having mobilenodes. In this paper, weexplore the effect on per se...
