Dissertation on Mobile Peer-to-Peer Systems and Services

Mikko Heikkinen, a former member of our research group and MoMIE project, will defend his doctoral dissertation on “Techno-Economic Analysis of Mobile Peer-to-Peer Systems and Services” on Friday, June 8th, 2012.

Heikkinen’s dissertation analyzes the effects of emerging mobile P2P-based services and systems in the technology and business domains of the Internet. The dissertation applies multiple research methods to case studies on novel distributed mobile services, developing frameworks for the analysis of such services, extending existing theories and methods for such analysis, and reporting results from surveys and usage measurements on relevant topics.

The main techno-economic challenges in deploying mobile P2P systems and services are related to business models, resources, incentives, usability, security, and policy. Based on value distribution and usage analyses, Heikkinen asserts that mobile P2P systems and services are transforming the technology and business domains of the Internet.

More information about the defense is available at Aalto University web pages. An electronic version of the dissertation is available here.

MoMIE project is proud of Mikko’s achievement and wishes him good luck to the defense!

Mobile Handset Population in Finland 2005-2011

MoMIE project has published a new report about the mobile handset population in Finland. The report is based on data collected from mobile operators (Elisa, TeliaSonera, and DNA) about active handsets observed in their networks. The data has been collected annually each September, between 2005 and 2011.

The report shows that Nokia continues to dominate the handset population in Finland: at the time of the latest study it’s share of active handsets was 81% (86% in 2010), and also the ten most popular handset models were from Nokia. The top ten list of handsets included mostly mid-priced feature phones, the most popular model being Nokia 2760 for a third consecutive year.

The share of smartphones out of all handsets is increasing steadily, reaching 33% of the handset population in 2011. Different versions of the Symbian operating system account for 26% of the handset population, followed by Android (5%) and iOS (3%). The share of smartphones out of all mobile handsets is also expected to keep growing fast: in September 2011 their share of handset sales was already 56%.

Among the increasing share of smartphones and advanced feature phones, the diffusion of advanced handset features also continues. For example, more than a half of the handset population now supports 3G (WCDMA), and WLAN (Wi-Fi) is found in over a quarter of the handsets. 3G is forecasted to reach 80% penetration in three years and WLAN in four years, assuming that the constant growth trends observed in the sales of devices equipped with these features continues.

The latest mobile handset population report can be found here. For more information, please contact Antti Riikonen (firstname.lastname@aalto.fi).

MoMIE publishes two new journal articles

MoMIE project has recently got two new journal articles accepted and published, both utilizing mobile handset-based measurement data. The articles focus on the study of contextual patterns of smartphone usage and user attitudes towards handset energy consumption, respectively.

Juuso Karikoski and Tapio Soikkeli co-authored an article titled “Contextual usage patterns in smartphone communication services“, which was accepted to the Personal and Ubiquitous Computing journal. Results of the study imply that people use smartphone communication services differently depending on the use context. Handset-based measurement data are used to analyze the usage of voice calls, email, SMS, and instant messaging / VoIP services. Use context is identified with an algorithm utilizing mobile network cell ID and WLAN data and resulting in five place-related contexts.

Mikko Heikkinen, Jukka K. Nurminen, Timo Smura, and Heikki Hämmäinen co-authored an article titled “Energy Efficiency of Mobile Handsets: Measuring User Attitudes and Behavior“, which was accepted to the Telematics and Informatics journal. In the article, the behavior and expectations of mobile handset users towards energy consumption was studied. Mobile handset measurements and questionnaire studies from subsequent years were used to study both the actual behavior of the users as well as their explicit attitudes, expectations, and experiences. The results show that mobile device users need better information of battery status and energy consumption. Users also want to understand and control the energy consumption of different applications and services. This article is joint work with the Data Communication Software research group at the Department of Computer Science and Engineering.

Congratulations and thanks to all the authors!

MoMIE project goes online!

The web pages of Aalto University’s MoMIE project were opened today. The project aims at measuring, analyzing, and modeling the mobile Internet ecosystem in Finland, utilizing various quantitative usage data accumulated by the market parties. The focus of the project is in the Finnish consumer mobile market and emerging mobile Internet services and applications. The project takes a multidisciplinary approach connecting technical, economic, and human aspects.

MoMIE project is managed by the Network Economics research team of the Department of Communications and Networking, at Aalto University of Finland.
