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.

SECURING AODV

Abstract
Some aspects of ad hoc networks have interesting security problems. Routing is one such aspect. Canned security solutions like IPsec are not applicable. The routing protocol Ad hoc On Demand Vector routing protocol has no security mechanisms. So, to improve the security there are somenew mechanisms like hash chains, double signature are using.

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.

A Mobile Ad hoc Network (MANET) comprises of mobile nodes that moves ind ....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

multipath aodv coding in ns2

Abstract

Video transmission is nowa days become a well established facility and has many applications.Video transmission over wireless network requires page link reliability. videos are having more data to be transmitted during communication. Traditional routing protocol suffers from limitation like page link failure. It motivates to Multi-Path routing scheme that provides reliability. There is also need to make modification during path selection in multipath protocol. It ispossible to enhance network lifetime wi ....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
