Problem description: | This thesis expands the third-party SOAP library ksoap2-android with the possibilities of using different transport protocols other than HTTP/TCP and using compression to reduce the size of SOAP messages. The additional transport protocols are UDP and AMPQ, and the compression tools added are gzip and EXIficient, an XML-specific tool that implements the Efficient XML Interchange format. The expanded ksoap2-android library was used in a Web service client application installed on an unrooted Samsung Galaxy tablet using the 4.2.2 version of the Android operating system. The Web service client was tested against different Web services with different transport and compression combinations, using a proxy server to adapt the messages to a COTS server. The testing was done over both mobile broadband and Wi-Fi to examine the effects the different combinations had on CPU load and battery usage of the Android device, and the network load.
The testing showed that while EXIficient compressed slightly better than gzip, it caused a much greater CPU load and battery usage that gzip, causing the expenses to absorb the profits. Both UDP and the AMPQ implementation RabbitMQ performed better than HTTP, especially when focusing on achieving a higher goodput. This thesis concluded that using gzip together with RabbitMQ is the better option when it comes to reducing network overhead while simultaneously maximizing battery lifetime of reliable SOAP communication on an Android device. |

Comments
Red line
Your thesis should have a "red line", which is visible throughout the whole thesis. This means you should mention in the beginning of each chapter how the chapter contributes to the "goals of the thesis".
Use of scientific methods
A thesis follows a standard method:
- describe the problem (problemstilling)
- extract the challenges. These challenges should be measurable, e.g. method is too slow to be useful to voice handover.
- Analyse technology with respect to challenges. Don't write & repeat "everything" from a certain technology, concentrate on those parts (e.g. protocols) which are of importance for your problem
References
- Wikipedia is good to use to get an overview on what is happening. But there is not scientific verification of Wikipedia, thus you should use wikipedia only in the introduction of a chapter (if you use text from wikipedia). Use scientific literature for your thesis.
- Scientific library is "at your hand", you can get there directly from UiO: [[How to get access to IEEE, Springer and other scientific literature -> Unik/UiOLibrary]]
- I suggest that references to web pages, e.g. OASIS, W3C standards, are given in a footnote. Only if you find white papers or other .pdf documents on a web page then you refer to them in the reference section.
Evaluation of own work
Perform an evaluation of your own work. Revisit the challenges and discuss in how you fulfilled them. Provide alternative solution and discuss what should be done (or what could have been done).
