A Mobile Ad hoc Network (MANET) comprises of mobile nodes that moves independently in an open environment. Communication between the nodes in a MANET is enabled with the aid of intermediate routers. The nature of MANET such as open medium, dynamic network topology, lack of centralized monitoring, and lack of clear defense mechanisms makes it vulnerable to several routing attacks. In MANET routing, there is a high probability for intermediate nodes to be malicious that might be a threat to the security. Grayhole is the common attack in ad hoc ro ....etc

In computer networking, a packet drop attack or blackhole attack is a type of denial-of-service attack in which a router that is supposed to relay packets instead discards them. This usually occurs from a router becoming compromised from a number of different causes. One cause mentioned in research is through a denial-of-service attack on the router using a known DDoS tool. Because packets are routinely dropped from a lossy network, the packet drop attack is very hard to detect and prevent.

The malicious router can also accomplish this at ....etc

Abstract

Recently, wireless sensor networks (WSNs) have been widely used in many applications, such as Smart Grid. However, it is generally known that WSNs are energy limited, which makes WSNs vulnerable to malicious attacks. Among these malicious attacks, a sinkhole attack is the most destructive one, since only one sinkhole node can attract surrounding nodes with unfaithful routing information, and it executes severe malicious attacks, e.g. the selective forwarding attack. In addition, a sinkhole node can cause a large amount of energy waste ....etc

implementation of sinkhole attack in dsr

Introduction

SinkHole attacks are one of the intrusion attacks that a MANET faces. In a SinkHole attack, the intruder node/malicious node sends fake routing information claiming that it has an optimum route to the target which causes other nodes in the Ad Hoc Network to route data packets through it. Thus, the malicious node gets access to all the traffic and is free to tamper the data as it wishes. In this example, we show how to implement a SinkHole attack on Manet running the DSR routing Protocol us ....etc

Black-hole attack implemented in tcl


Hole Attack Implemented In TCL

In sample20.tcl, while simulating Blackhole attack in MANET, the blackhole attacker does not obey the communication model. Data Transmission is established between nodes using UDP agent and CBR traffic. Sender sends the data via attacker. Source node transfers data to attacker that does not have shortest route to Destination. Attacker does not forward data to its neighbors.

ABSTRACT

A Wireless Sensor Network (WSN) consists of autonomous sensor devices that are used to monitor physical and environmental conditions like temperature, pressure etc. The WSN is built of hundreds and thousands of detection stations called nodes, where each node consists of one or more sensors. Each WSN consists of a radio transceiver, an internal/external antenna, a microcontroller and a battery. Wireless sensor networks are
the networks that are used to communicate by sensing the beh ....etc
