Transcript A PowerPoint presentation of potential Project

Project: Simulation in NS
• Learn how to use NS-2
• Examine 2-3 papers that do benchmark
studies
• Implement a simulation of the Drexel
TAARP routing protocol
• Using procedures in the papers,
benchmark TAARP with OLSR and AODV
– NS-2 code should exist for OLSR and AODV
• Write up the results
Project Idea #1
Project: Campus 802.11 RF Map
• Create a tool for 802.11 RF
mapping
– Signal quality at a given
location
• Track the multiple access
points visible at each
location
– Each point on campus gets a
vector of AP & signal levels
• Inside and outside
• GPS card will be provided
Project Idea #2
Project: Link Quality Study
• Reproduce the results in
– Understanding link quality in 802.11 mobile ad
hoc networks, Gaertner, G.; Cahill, V.; Internet
Computing, IEEE, Volume 8, Issue 1, JanFeb 2004 Page(s):55 – 60
• Perform studies for 802.11a and 802.11g
• Develop 2-3 scenarios for testing a/b/g
– Indoor, line-of-sight, treed area, subway
• Document results
Project Idea #3
Project: Survey & Package
• Write a survey about the currently available set
of OpenSource 802.11 auditing and security
tools (including their current level of support)
– i.e. war driving, intrusion, network auditing, etc
• Package a set of tools for a home user to test
the survivability and security of their network
(802.11 a/b/g)
– Including website, download pointers, installation
summary, documentation
– Windows, MAC, and Linux Versions
Project Idea #4
Project: Where am I?
• Finding yourself in buildings is very hard
• Using signal data from DragonFly access points
nodes, create a tool that will tell you
– What building you are in
– What floor you are on
• Overlay this information on a map of Drexel’s
campus (i.e. using tcl/tk, java or perl/tk)
• Package this for download for Drexel students
Project Idea #5
Paper: MANET Routing
• Using NS-2 or the Drexel MATES
simulator, implement and benchmark
routing protocls
– AODV, OLSR and another two algorithms of
of your choosing
Project Idea #6
Project: MESH vs MANET
• Compose a survey paper about Mesh vs
MANET networks
• Include at least 20-30 references
• Document scenarios when one is better
than the other
Project Idea #7
Project: Attack WEP
• Using freely available open source code, set up
the following scenario
– User is surfing the web
• i.e. set up a computer with a script to poll web pages (i.e.
nytimes.com)
– Intruder captures packets from user
• Questions
– Can you break in? How long does it take? Can you
measure this? Does the surfing pattern matter? Try
64bit and 128 bit keys… etc.
– What other variations to this can you suggest?
• Write report
Project Idea #8
Project: Home Wireless Self Test
• Create a tool that can run as a background
process
• User specifies his own network
• Tool passively sniffs this network trying to
crack the wep/wpa/etc keys
– Must restrict memory footprint
• When it does, it raises an alarm (time to
change keys)
Project Idea #9
Project: MANET Routing &
Performance
•
•
Set up a system with Linux and the OLSR INRIA implementation from the
U.S. Office of Naval Research mods (http://pf.itd.nrl.navy.mil/projects/olsrv3)
Tasks
–
–
–
–
–
–
–
–
–
Install OLSR software in Linux
Configure so that test can be done for IEEE 802.11 a, b and g ad hoc networks
Synchronize time with a “controlling”:node
Use iperf to measure throughput with a directly connected topology
Two teams in each network run iperf servers
Two teams in each network run iperf clients
Create a multi-hop topology and repeat the test
Save results
Try with several applications (I.e. H323 or SIP based audio or video conferencing
tools)
– Try is several operational environments (campus, 30th street station, etc)
Project Idea #10
Project: Observe Security Issues
•
Objectives:
– Observe security vulnerabilities in wireless local area networks, especially Denial
of Service (DoS) attacks that target IEEE 802.11 WLANs
– Observe the operation of an 802.11 WLAN detector, sniffer, and Intrusion
Detection System (IDS)
•
•
Special software: Kismet – a layer 2 wireless network detector, packet
sniffer, and intrusion detection system
Tasks
– Spoofing the Intel gateway’s IP address (ARP cache poisoning): One student
spoofs the IP address of the access point and, under some conditions, “poisons”
the ARP cache entries of other nodes in the network
– Network sniffing, detection, and intrusion detection: Kismet is used to monitor
IEEE 802.11b traffic
– Impersonating an access point: set up a computer to impersonate an access
point and cause other nodes to disassociate from the real access point
Project Idea #11
Project: Implement a Paper
• A team of 1-2 students, try to reproduce
the work (or a subset of it) in
– http://www.cs.rice.edu/~arudys/papers/mobico
m2004.pdf
Project Idea #12
Project: Universal Remote for
Wireless Networks
• The challenge: wireless networks have
literally hundreds of parameters
– Power, frame sizes, ack rates, etc
• Write an application (java?) to expose the
controls for Cisco Aironet cards running
under Linux
Project Idea #13
Project: Interference Analysis
• Examine the relationship between
– 802.11 a/b/g channel selection
– Thru-put
• In environments where there are
competing networks
• Do ‘nearby’ channels have an effect?
What kind?
Project Idea #14
MAC Project
• Design and Prototyping project
• Test harness for adding limited
application level MAC features to 802.11
provided (with RTS/CTS and ACK’s
turned off)
• Linux PC AP and client platforms with
modified drivers, etc. provided by Z. Wu
• Design document (full description, flow
charts, pseudo-code, etc.) and prototype
demo as deliverable by April 15.
Project Idea #15
MAC Project
• 802.11 protocol extensions
AP test harness
for application level
MAC development
Client test harness
for application level
MAC development
Project Idea #16
MAC Project
• Design MAC reservation and scheduling
extensions to provide flow QoS for 1,2..n
users. Test with 3 UDP sources
generating ~0.5, 1, 2 Mbps. Measure
connection setup delay, flow rate,
overhead, net throughput and packet loss
rates.
OR
Project Idea #17
MAC Project
• Design MAC reservation, error control
and scheduling extensions to provide fast
downloading of large files to 1,2..n users
with simultaneous requests. Prototype
with 3 users each downloading a 10 MB
file using TCP. The goal is to minimize
total elapsed time for delivering all 3 files
to completion.
