TKT-2301/2307 Student application Mobile node locator Group number: 118 Student name: Mauno Piililä Student name: Panu Sjovall 1

Overview and purpose Key idea Show mobile node positioning and routing information Purpose Is to provide informative information for system problem and efficiency improvements TKT-2301/2307 Student Presentation 2

Motivation Why this application? While using WSN system, it seemed obvious that this kind information could be helpful when placing fixed nodes. What is its target benefit(s)? Better signal coverage for mobile node 3 TKT-2301/2307 Student Presentation

Motivation Is it possible to measure benefits and how? Benefits can be seen when creating network for new area or when solving problems in existing network If there are some existing solution, comparison to it WSN web interface but its not so informative 4 TKT-2301/2307 Student Presentation

Users What kind (experts, consumers, kids, real estate owners, …) This program is mainly targeted for system maintainers How many Our web interface shows data to anyone Only one at the time can query special information but others may view 5 TKT-2301/2307 Student Presentation

General user interface requirements What devices and programs required for the end user HTML and JavaScript capable browser Is it required to have continuous UI operation (”on” all the time?) No, not necessary 6 TKT-2301/2307 Student Presentation

General user interface requirements Several users? Only viewing, not multiple queries allowed or those distracts others at the moment Future development TKT-2301/2307 Student Presentation

General WSN requirements What information is required from WSN? At least routing and neighbor data and (possibly) measurement data? What basic principle(s) is applied Positioning (Possibly monitoring and/or alarming) 8 TKT-2301/2307 Student Presentation

Meaning of WSN Data Location (where data originated) Node that has been queried shows on graphical map Period of use / of interest Monitor mobile node location and signal strengths User rights (who and at what time) There are none Interpretation of the data (as such or indirectly using multiple factors) What is reported/displayed to end user 9 TKT-2301/2307 Student Presentation

Meaning of WSN Data Interpretation of the data (as such or indirectly using multiple factors) Graphical view should be quite self explanatory. What is reported/displayed to end user Lines between nodes are routes and circles represent signal strength 10 TKT-2301/2307 Student Presentation

User interface design What kind of reports and views are given to the user Web interface that shows locations, routes and neighbors graphically. Possibly some other information as a text like measurement data from sensors What user can select / configure Sketch of UI ”screens” 12 TKT-2301/2307 Student Presentation
