Overview and purposeKey ideaPurpose

Note: It is expected that you present one application that can be implemented with “TKT-2301/2307 kind of WSN” but not limited to it – still try to keep your application requirements reasonable

MotivationWhy this application?What is its target benefit(s)?Is it possible to measure benefits and

how?If there are some existing solution,

comparison to it (use multiple slides if necessary)

General user interface requirements

(you can mention both what is available at the course and what could be used in principle)

What devices required for the end userWhat end-user programs requiredIs it required to have contiunous UI

operation (”on” all the time?)Several users?


General WSN requirementsWhat information is required from

WSN?Measurement / diagnostics data?

What basic principle(s) is appliedMonitoringPositioningAlarming


Meaning of WSN Data

(use additional slides to explain how these are to be handled)

Location (where data originated)Period of use / of interestUser rights (who and at what time)Interpretation of the data (as such or

indirectly using multiple factors)What is reported/displayed to end user

Criteri Question Score Comment

User Self-explaining information Interpretation of data requires special expertise ?

Only essential information is displayed

User must seek interesting information by himself from large data set / stream?

User's attention is involved only when necessary

User must watch information all the time?

Multiple simultaneous access Several users for same data?

System Existing devices used for user interface

PC, mobile phone enough?

No special programs required Standard web browser is enough for user?

Interoperability with other systems

What interface technologies are used?

Feasible performance requirements

Temporary/permanent WSN data storage requirements?
