BackgroundWireless Sensor Networks

• Usable technology available for less than a
  decade
• Growing number of sensors and need to gather
  information generate need for WSN applications
• Military applications
• Health monitoring
• Vehicle tracking and detection
• Wireless communication getting more popular
• Wireless sensor network topology and protocols
  still under development
• Needs to be simple, efficient, low-power, robust,
  low-cost, etc

3
BackgroundRoad Construction

• Very complex and hectic environment
• Many processes and work phases are done manually
• Multiple subcontractors and machines from
  different manufacturers
• Normally small companies
• VTT Electronics has developed and tested wireless
  communication possibilities
• Need to share information more efficiently

Using WSN as Part of a Road Construction
SiteRequirements

• Robust and fault tolerant
• Low-cost
• Scalable
• Universal
• Easy to use
• transmission and topology
• invisible to user.
• Low power consumption

5
Using WSN as Part of a Road Construction
SitePossibilites

• Vast international markets
• Many possible applications from billing to
  automated machines
• Large number of sensors and users
• Current technology level low
• Fierce competition

6
Using WSN as Part of a Road Construction
SiteProtocol Needs

• Robust
• Secure
• Fast transmission
• Good transmission range
• Usage of different wireless technologies
• GPRS, GSM, WIMAX, WLAN
• Simple interface to hardware and application
• Simple universal language

7
Using WSN as Part of a Road Construction
SiteExample Applications

• Sensor and actuator collaboration between
  machines
• Loading gravel to a truck
• Grinding a road
• Automation of processes
• Billing using database and machine communication
• Assignment of work schedules
• Quality control of a road
• Maintenance scheduling
• Work supervising

8
Proposed Schematics

• Sink controls local nodes
• Nodes have unique ID
• Locally nodes can communicate without the sink
• Nodes include sensors and actuators
• Sinks relay the message to outside
• Sink allows usage of a node from outside
• Physical layer uses available wireless
• technologies
• Data link layer and MAC includes secure and
• ID features
• MAC releases the packet to the network layer
• in standard format
