Project Idea

1
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

2
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

3
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, Jan-Feb
  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

4
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

5
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 Drexels
  campus (i.e. using tcl/tk, java or perl/tk)
• Package this for download for Drexel students

6
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

7
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

8
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

9
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)

10
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 controllingnode
• 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)

11
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 gateways 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

12
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/mobicom2004.
  pdf

13
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

14
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?

15
MAC Project

• Design and Prototyping project
• Test harness for adding limited application level
  MAC features to 802.11 provided (with RTS/CTS and
  ACKs 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.

16
MAC Project

• 802.11 protocol extensions

AP test harness for application level MAC
development
Client test harness for application level MAC
development
17
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

18
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.
