Motivation

Sensor Nodes Sensor Network

Example Applications Problem Statement

Sensor installation on demand• Avoids proactive

Maintenance• Robust and self-healing• More application possibilities

Manual installation cumbersome

Project Status: FlySense

DMRC assembled deployment mechanism

DMRC assembled WSN node casing

Miniaturized embedded WSN nodesbased on ATMEL ATMEGA128RF

8

Project Status: FlySense

Well established deployment mechanisms based on regular tessellations

Deployments based on channel measurements

A

B

C

A and B already deployed. Position of C to be determined based on channel quality between A and B.

Subject of investigation: Increased coverage with the same network quality or same coverage with increased network quality.

Subsequently built network based on channel measurements

The Task for this Semester: Find the sensor

?

10

The Plan for this week

Start to research existing literature about already proposed solutions in this area (you can start with the reference list of the TPDS paper)• You can ignore solutions which do not match our assumptions (i.e. the

copter is equipped with GPS, the sensor node has only a wireless communication interface, the sensor node has no prior knowledge about its location)

• Prepare a short summary of all found solutions which we discuss in the next meeting

• Coordinate yourself who handles which paper Get acquainted with the documents about the previous projects

• Go through the documents Positionierung1.pdf and Positionierung2.pdf to see the problem encountered with finding the strongest RSSI-Value

• Briefly skim the project group reports FlyNet II.pdf and FlyNet III.pdf to get a first impression about the hardware

11

The Plan for Next Week

Plan the first milestones Form groups (if at all) Every group has a responsible project leader (changes over the

semester)• Coordinates with other group leader• Communicates with us• Presents the milestone

(Hardware will then be available as well)

12

The Plan for this Semester

Regular meetings (e.g. every 14 days) Every group has a current milestone with a deadline Every group has to report about the success

(this will be the base for the grades; hand in your slides)

At the end (in August):• Demonstrate the Prototype (video, measurement data)• Hand in a project report (this will be graded as well)
