Thesis: Research Topics in Wireless Networks

1
Thesis Research Topics in Wireless Networks

• Telecommunications Networks Group
• Politecnico di Torino

2
Mesh Networks

• Networks using the IEEE 802.11 or the WiMax
  standard, including both fixed and mobile nodes
• Routing using a modified version of OLSR
• Mechanisms for favoring node cooperation
• Both simulation (ns2) and experimental research
  (mesh boxes)

3
Vehicular Networks (or MANET)

• Highly-dynamic topology
• Distributed system
• GPS-aided
• Need to keep the communication overhead low

4
Information Sharing

• MANET as a pure peer-to-peer system (nodes are
  both clients and servers)
• Protocols and algorithms to le the users share
  information
• How many nodes and which nodes should cache the
  information
• How much infomration should each node cache, and
  for how long?

5
Information Sharing

• Methodology
• Simulation via ns2 and OMNET
• Theoretical analysis

6
Video Streaming in VANETs

• Vehicles are synchronized -gt TDMA is feasible
• Interaction between application (video coding)
  and network/MAC layer
• Efficient use of radio resources
• Methodology
• Simulation via ns2
• Theoretical analysis

7
Sensor Networks
Sink
Internet, Satellite, etc.
Sink
8
Channel Access and Routing

• Sensor networks for event detection and object
  tracking
• Modeling and simulation of channel access and
  routing
• Study of the quality of monitoring

9
Quality of the Reconstructed Signal

• Sensors provide an irregular sampling of the
  phenomenon (signal)
• Nyquist Theorem does not apply
• Under which conditions can we successfully
  reconstruct a signal?
• Whats the impact of the network characteristics
  (e.g node density) on the quality of the
  reconstructed signal?
• Methodology theoretical analysis and numerical
  results through Matlab
