Wireless Sensor Network - course: Project to investigate requirements and applications using wireless sensor networks on a construction site Ykä Marjanen

Background: Wireless 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 11.1.2019

Background: Road 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 11.1.2019

Using WSN as Part of a Road Construction Site: Requirements Robust and fault tolerant Low-cost Scalable Universal Easy to use; transmission and topology invisible to user. Low power consumption 11.1.2019

Using WSN as Part of a Road Construction Site: Possibilites Vast international markets Many possible applications from billing to automated machines Large number of sensors and users Current technology level low Fierce competition 11.1.2019

Using WSN as Part of a Road Construction Site: Protocol 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 11.1.2019

Using WSN as Part of a Road Construction Site: Example 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 11.1.2019

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 11.1.2019
