Title: Mobile Computing: Wireless Mesh and Sensor Networks

Mobile Computing Wireless Mesh and Sensor
  • Thomas Kunz
  • Professor and Director
  • Technology Innovation Management Program
  • Carleton University

Mobile Computing Group at Carleton
  • Facilitate the development of innovative
    next-generation mobile applications on
    resource-constraint, mobile devices
  • Develop the required network architectures
    (MANETs, wireless mesh networks, wireless sensor
  • Research into network protocols (MAC, routing,
    Mobile IP, QoS support, transport), and
    middleware/runtime support

Wireless Mesh Networks

Wireless Mesh Testbed
Wireless Mesh Testbed (cont)
  • Mesh routers IXP 425 based nodes with two radios
  • Provide local footprint/soft AP functionality to
    clients over one radio
  • Use second radio for building IPv6 based mesh
    OLSR routing protocol with QoS extensions
  • Mesh testbed built with close collaboration from
    one small Ottawa startup
  • Some routing work licensed to another Ottawa
    company and being productized in their Adaptive
    Intelligent Router offering

Current Wireless Mesh Research
  • Capacity and Fairness
  • WMN shared resource for all users
  • WMN have finite (and rather limited) capacity to
    support a number of users
  • Goal maximize utilization of network while
    providing fair access to all users
  • Analytical performance bounds
  • Distributed algorithms/protocols
  • Definition of Fairness
  • Tradeoff Fairness vs. Utilization
  • Generating Routing Protocols automatically
    using Generative Programming approach GP-Pro
  • Network Management for Dynamic Networks
  • Maritime Network Policy-based Network Management

(Wireless) Sensor Networks
(Scenario developed by RUNES project
WSN Research
  • Developed new localization and clock
    synchronization algorithms
  • Currently setting up a WSN testbed (jointly with
    Prof. St-Hilaire)
  • Ongoing research
  • Evaluate above algorithms in testbed, extend them
  • Capacity in multi-hop wireless networks (network
  • Security bootstrapping trust without prior
  • Application-oriented overlay networks
  • XML Aware Wired Networks/World Wide Sensor Web
  • Model, discover, and interact with distributed
    sensors based on XML standards
  • efficient distribution of different information
    derived from the sensors to various interested
    parties (first responders, airport authorities,
    etc.) content-based routing
  • combine/fuse data derived from different sites

SENECA Sensor Networks for Canada
  • Proposed NSERC Strategic Network
  • 7 Canada Research Chairs, 3 other researchers
    from UQO, University of Ottawa, University of
    Sherbrooke, Ecole Polytechnique, Carleton
    University, ISMER, Concordia
  • Partners End users (CATSA, CBSA, EC),
    manufacturers (Fiso, Biophage Pharma, Enablence,
    IR Photonics, .)
  • Goal Hybrid integration of photonics-based
    sensors and wireless networking
  • Structured around three themes
  • Application-specific Sensor Communication and
    Integration Technologies
  • Application-Specific Photonic Devices and
  • Enabling Photonic Materials, Fibers and
    Processing Technologies
  • Selected Applications for Wide Area Photonic and
    Wireless Sensing
  • remote detection of explosive materials and
    biological hazards
  • measure nutrient and contaminant concentrations
    in water
  • geo-fencing solutions to protect critical

Prof. St.-Hilaire Wireless Sensor Networks (WSN)
  • Research in planning algorithms (both static
  • How to design new WSN in a cost effective way
  • How to update an existing WSN infrastructure
  • Organisation (re-organisation) of the nodes to
    maximize the life time of the network
  • Research on network protocols
  • Routing scheme with different objectives
  • Save energy, minimise delay or combination
  • Re-organise the route in case of node/link
  • Correlation of events both in space and time
  • Clock synchronisation
  • Localization algorithm

Prof. St.-Hilaire Wireless Sensor Networks (WSN)
  • Research on data association
  • How to follow multiple moving targets such as in
    military applications, border defence and so on.
  • Research on data aggregation/fusion
  • Aggregate data in order to save bandwidth,
    computing resources, battery life, etc.
