Choose Android Device 

An android tablet device will need to be selected. The device will most likely need to contain access to cellular networks as well as have a very accurate WiFi receptor.

Complete WiFi Survey App   

We will need to complete our WiFi logging application for the Android Tablet device, this application will be used to log the data of each point in a N, E, S, W directions. This app will have very simple user interface of a “start logging button”, “direction button”, and the ability to identify point number. If it is not possible to create this survey app in the given deadline the already freeware program “insider” will be used in its place to log the data.

Select Test Site   

The test site will be in the Vari Hall building. The initial area will consist of the first floor of the dome area in the Vari Hall building and will expand outwards on successful results. This will be done to keep this project as simple and as attainable as possible.

Test Surveying App Software  

The app will be analyzed to see if it’s working properly by checking to see if it saves the files properly this will include how to format the data. As stated before if the app is not working properly by the deadline insider will be used in its place.

Final Exam Break 

Since all of the group members are also taking a full course load on the side of this project, there will be a study break for the exams running

Select and Monument Survey Grid   

The grid spacing will be chosen to optimize the accuracy well at the same time taking the minimum amount of time to collect. Solomon recommended using a grid spacing of slightly more than a meter for a smaller test area. Larger grid spacing will be used if the implementation area were to expand significantly.

Surveying Test Area     

The initial implementation area will be surveyed over the course of a couple days. Each WiFi fingerprints will be measured in four orientations North, East, South and West. Each orientation corresponds to the direction towards the face of the building roughly perpendicular to that direction. The Surveying will be done with either our developed app or the pre-established “insider” software. Each fingerprint will need to be properly labelled on the floor plans in order for the database to be organized and assembled.

Process Data   

The raw surveyed fingerprints need to be processed and sorted. This will be done to check for outliers. This will also involve sorting the raw data into a suitable format to be easily queried and analyzed.

Georefrencing floor plans  

Use ArcMap to georefrence floor plans. Render the gridded (georefrence) survey area on the floor plans.

Select data structure   

Choose an optimal storage structure for the raw surveyed data. Research requirements for the structure based on the server query parameters for fetching data. At this point a final decision will be made on whether calculations will be cloud-based or preformed natively on the device.

Develop/Implement the algorithm to resolving positions   

Investigate any changes that need to be implemented in Solomon’s algorithm for resolving locations of fingerprints. Implement changes as necessary. Ask Solomon for assistance and advice relating to the selected data structure.

Testing of location resolution  

Test Solomon probability based algorithm for resolving locations of fingerprints using input based on the selected data structure. Preliminary QA and statistical analysis of results.

Integrate Algorithm to the Phone App  

Integration of Solomon probability based algorithm. Conversion to native Java-Android language.

Android Map Integration   

Gather available floor plans and maps for server upload. Work with Hadi to incorporate ESRI mapping tools. Investigate native navigation and geolocation methods available from the ESRI toolbox.

Server Access  

Select Storage Server Store surveyed finger print data base on server in the format of selected data structure.

Final Field Testing   

Attempt to resolve locations at known points. Test location resolution for points ON grid marks. Test location resolution for points between grid marks.

QA & Analysis of results    

Statistical analysis of location testing results. Accuracy of system. Reexamine and comment on system limitation. Discuss results and compare to expectation.
