This guide will provide you all the steps to download, import and run the BenchImage application, which can be used to demonstrate MpOS functionalities for both Android and Windows Phone platforms.

Developers

In this tutorial you'll see how to run BenchImage app with MpOS

Technologies used:

Clone the MpOS project from github
Windows 8.1 (x64) Professional (for Linux and Mac OS X only Android side works)
Android side:

Eclipse Platform 4.2.1v with ADT 23.0.x
Oracle Java SDK 8.x (for any OS)
Android SDK installed (API 19 or above)

Windows Phone side:

Visual Studio Professional 2013 (with Update 4) or Community 2013 (not tested)
Visual Studio SDK 2013 (with Update 4)
Windows Phone emulators (need Win 8.1 x64 Pro with client Hyper-V installed)

Import Android components on Eclipse ADT

Open Eclipse ADT and follow this steps (jump to next section if you know how to import in eclipse)

Import -> Android -> Existing Android Code Into Workspace

Browser the path where Project was cloned '<cloned_path>/android' and click on "OK" button

Selected the “BenchImage2” and “MpOS API” to import and click on “Finish” button

In each project “BenchImage2” and “MpOS API” go in Properties -> Android -> Selected 
"Target Name: Android 4.x" and click on "OK" button

You’ll see the projects “BenchImage2” and “MpOS API” on eclipse workspace. In BenchImage2 has an MainActivity to start the mobile app.

Note: In order to test the ‘BenchImage’ application, it is recommended to use a device with Android 4.0.X or above, because of the multicast-based discovery system. Emulator is not recommend either.

Import Windows Phone components to Visual Studio 2013

Browse the path where the project is located.
Enter in the “windows_phone” folder.
Click on “MpOS.sln” in order to open the project on VS 2013.

Note: For test the BenchImage2 app is recommended to run in device using the Windows Phone 8.x or above.

Execute the MpOS Plataform

Browse the path where the project is located:

cloned directory -> folder "plataform" -> folder "executables"

configure the machine IP in config.properties "cloudlet.interface.ip"

Open Prompt (or console) and navigate again to “executables” folder
Execute this command:

java -jar mpos_plataform.jar

Note: To kill the application on Prompt is using the “Ctrl+C”.

Note2: You should check the firewall permissions to allow mpos_plataform.jar to run properly. And also if the wireless access point supports multicast protocol.

Execute the BenchImage app

Execute BenchImage on Android using the Eclipse ADT and on Windows Phone using the VS 2013. When you load the mobile app, selected on:

“Filtro” -> Original to Cartoonized;

“Processamento” -> Local to Cloudlet;

Press “Inicia” to starting the offloading application and as resulting you’ll see the figure with cartoonizer filter.

Note: On system monitor maybe you’ll see the high network activity and fast app executing when compared with “Local” executing on “Processamento”.

Note: On MpOS Plataform CLI, you’ll be able to see the multicast and deployment services working. And you’ll also able to see a high network activity when the offloading system is working. Depending on the mobile device, execution environment and network conditions, the filter should be executed faster outside of the mobile device (Cloudlet or Internet).

Contributing

In general, we follow the fork-and-pull git workflow:

Fork the repository on GitHub
Commit changes to a branch in your fork
Pull request "upstream" with your changes
Merge changes in to "upstream" repository

⚠️ Be sure to merge the latest from "upstream" before making a pull request.
