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

Introduction

This assignment aims at making the students familiar with the reactive (on-demand) routing protocols used in ad hoc networks and compare the performance of DSR and AODV protocols.

Performance Metrics used

We will evaluate the routing protocols in terms of two metrics-
1. Packet Delivery Fraction/Ratio : It is the ratio of packets delivered to that transmitted by the source.
2. Routing Load : It is the number of routing packets sent per data packet delivered.

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

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

source code for sinkhole attack using ns2 simulator

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

Abstract

A MANET (Mobile Adhoc Network) is an infrastructure-less self configuring wireless networks of routers. It has potential applications in totally unpredictable and dynamic environment. Routing protocol used here is a form of reactive routing called AODV. AODV (Adhoc On Demand Distance Vector) routes based on demand. The major benefit of AODV is minimum connection setup delay and assignment of sequence numbers to destination to identify the latest route. The route updates are done by periodic beaconing. This network is susceptible to va ....etc

its just been a while since i used ns2.
i am trying to play around with the AODV protocol in ns2.
there,inside ns2/aodv directory,i find files such as aodv.cc,aodv.h,aodv_logs.cc etc.. please expalin me in detail what are these files and how they work together.
if you have the page link to answer my query,i would be more than happy
thanks in advance. ....etc
