Mobile World Congress - First Impressions

Monday, 02/25/2013, 12:56:44

Mobile World CongressThe Software Campus provided me the great opportunity to visit the Mobile World Congress in Barcelona. Being here, I can say that the MWC is huge and a once-in-a-lifetime experience!

It seems like that the whole city of Barcelona concentrates on this event. It started at the airport with a team of MWC organizers waiting for arrivals to lead them to almost 15 flight check-in counters that were solely serving as a fast track registration for the congress. You see people outside and in your hotel walking around with MWC bags that you get during registration. The subways are full of people making it hard to find a little spot to stay and you also see organizers standing in subway stations to lead the people to the right train station going to the congress. These experiences really make you feel special as being part of a big event and I really appreciate that Software Campus gave me the opportunity to experience that.

Crowdsourcing in the OpenMobileNetwork

Monday, 12/31/2012, 16:10:09

Mobile network operators usually keep the data about their mobile network topology very secret. However, having this data, many sophisticated applications could be realized. Today's smartphones provide the means to measure cell data with which the mobile network topology of different operators can be approximately derived. The OpenMobileNetwork uses those smartphone clients and collects cell data via a crowdsourcing approach in order to establish a complete database of base station and WiFi access point locations, their coverage areas, neighboring cell relations and live data, such as traffic, service usage, and number of users.

OpenMobileNetwork for Android (OMNApp)

OpenMobileNetwork for Android (OMNApp) is a background service that actively collects mobile network data in a crowdsourcing approach in order to estimate and derive base station and WiFi hotspot positions. It further acquires live measurement data, such as the total traffic produced on smartphones or service usage information, in order to enable the modeling and visualization of the current/historic state of the network.

Jewel Chaser

Jewel Chaser is a location-based game in which you collect virtual jewels by moving to locations in the real world. While you play the game, mobile network and wireless access point data is collected for the OpenMobileNetwork in order to enrich the existing database.

In order to play it, just click on Start Collecting, check the map, and go towards one of the symbols shown on the map. As soon as you are close enough to a jewel, it will be collected automatically. However, you need to have the map open in order to collect the jewel. This means you can check where the jewels are, close the app, and open it later again as soon as you are close to one of the jewels. In order to collect jewels, your GPS has to be turned on.

Crowdsourcing - your help is appreciated!

By using those apps, you contribute with your data in building an open-source semantic dataset for mobile networks within the OpenMobileNetwork research project. These apps do not acquire any personal information from you. Thank you for supporting this open-source research initiative!

ComGreen Final Workshop & Project Extension

Friday, 12/14/2012, 16:31:10

After two years of hard work, the ComGreen consortium presented their results in today's final workshop to a big audience consisting of representatives of the BMWi as well as DLR, and other interested people. You will find more information on the IT2Green website and on the invitation flyer.

Abdulbaki presents the OMNSNET was involved in three different demos. The first demo was the ShowTable that was also presented at this year's CeBIT, whereas the second demo showed the interworking between the Multi-RAT Testbed and the Context Manager integrated into it.
I demonstrated the OpenMobileNetwork and how the interlinked semantic data can be useful in order to establish a power management in mobile networks. For this purpose, we extended the OpenMobileNetwork by several new features, such as dynamically calculated coverage areas, neighbor relations or traffic generated by smartphones at runtime. Furthermore, we enhanced our visualization by a ComGreen button that runs the following SPARQL query in order to determine the cells that are candidates for network optimizations in the area of Schöneberg: "Request all T-Mobile base stations that cover Telekom in Schöneberg with traffic below 4 Mbits and neighbors covering the same area by 70%".

OMN ComGreen Visualization

Please feel free to have a look at the special OMN ComGreen Visualization. You can see live traffic produced by your smartphone, if you run OpenMobileNetwork for Android (OMNApp), which is available for download at Google Play Store.
In addition, we also showed how cell data coming from the OpenMobileNetwork can be exploited for power management predictions.

All in all, it was a very interesting and successful event!

ComGreen Project Extension

Due to the fact that our project was very successful, the BMWi and the DLR decided to extend the project until April 2014! In this time frame, we will work on further aspects, such as delay-tolerant services in ComGreen scenarios and user movement predictions in the OpenMobileNetwork.
