MobiCa: Mobile Cloud Computing Language
Deciding whether to offload some computation is a crucial issue in mobile cloud computing systems. Various proposals in the literature try to face this problem taking decisions at design time, relying on the developer’s expectations or basing the choice on resource usage prediction. We propose a new methodology based on a formal framework, whose goal is to provide runtime support for offloading decisions. By means of a domain specific language (MobiCa), a developer can define both system and application structure, in terms of devices involved, computational power, code partitioning, required memory etc. Using a formal verification technique, based on the well-known model checker UPPAAL, the framework provides exhaustive and automatic decision support for offloading decisions. Using the resulting trace generated at runtime by UPPAAL, driven by some optimization query verified on the timed automata model associated with the MobiCa specification, the framework decides which fragments should be remotely executed. This process allows one to reduce memory and battery consumption, ensuring at the same time the best system performance.

- Stand-alone MCC compiler download
- Eclipse plugin link
- Navigator MobiCa example download
- Navigator UPPAAL example download (equipped with the verification queries)
Stand-alone: Download in a target folder the MCC compiler and the MobiCa example. Unzip the MobiCa example and from the terminal move to the target folder and run the compiler.
java -jar MCC-compiler.jar navigator.mcc
The system will create a src-gen forlder containing the Network.xml file directly editable from UPPAAL.
Eclipse plugin: Download an Eclipse IDE for Java Developers and install the plugin.
Help ->Install New Software -> Add
select MobiCa, click next and then finish.
click OK for security warning and then restart Eclipse.
For create a new MobiCa project File -> New -> Project.
Insert the name and press Finish.
Right click on MCC project in the Package Explorer -> New -> File
Insert the file name with extension “.mcc” and press Finish.
Click yes for accept the MobiCa view and start to edit the navigator file according the MobiCa syntax.
Once completed the editing, save the file (Ctrl+s) and eclipse automatically generate the UPPAAL input file in: MCC project -> src-gen -> “name of the system”.xml.
Open the generated .xml file with UPPAAL and perform some analysis.
