Abstract The ubiquity of mobile devices has opened up opportunities for a wide range of applications based on photo/video crowdsourcing, where the server collects a large number of photos/videos from the public to obtain desired information. How- ever, transmitting large numbers of photos/videos in a wireless environment with bandwidth constraints is challenging, and it is hard to run computation-intensive image processing techniques on mobile devices with limited energy and computa- tion power to identify the useful photos/videos and remove redundancy. To address these challenges, we propose a framework to quantify the quality of crowdsourced photos/videos based on the accessible geographical and geometrical information (called metadata) including the orientation, position, and all other related param- eters of the built-in camera. From metadata, we can infer where and how the photo/video is taken, and then only transmit the most useful photos/videos. -
Chapter # 1 Introduction
Chapter # 1 Introduction Mobile applications (apps) have been gaining rising popularity dueto the advances in mobile technologies and the large increase in the number of mobile users. Consequently, several app distribution platforms, which provide a new way for developing, downloading, and updating software applications in modern mobile devices, have recently emerged. To better understand the download patterns, popularity trends, and development strategies in this rapidly evolving mobile app ecosystem, we systematically monitored and analyzed four popular third-party Android app marketplaces. Our study focuses on measuring, analyzing, and modeling the app popularity distribution, and explores how pricing and revenue strategies affect app popularity and developers’ income. Our results indicate that unlike web and peer-to-peer file sharing workloads, the app popularity distribution deviates from commonly observed Zipf-like models. We verify that these deviations can be mainly attributed to a new download pattern, to which we refer as the clustering effect. We validate the existence of this effect by revealing a strong temporal affinity of user downloads to app categories. Based on these observations, we propose a new formal clustering model for the distribution of app downloads, and demonstrate that it closely fits measured data. Moreover, we observe that paid apps follow a different popularity distribution than free apps, and show how free apps with an ad-based revenue strategy may result in higher financial benefits than paid apps. We believe that this study can be useful to appstore designers for improving content delivery and recommendation systems, as well as to app developers for selecting proper pricing policies to increase their income. -
Asymmetric Peer Influence in Smartphone Adoption in a Large Mobile Network
ASYMMETRIC PEER INFLUENCE IN SMARTPHONE ADOPTION IN A LARGE MOBILE NETWORK Qiwei Han, Department of Engineering and Public Policy, Carnegie Mellon University, 5000 Forbes Avenue, Pittsburgh, PA 15213, USA and Instituto Superior Técnico, University of Lisbon, Av. Rovisco Pais, Lisbon 1049-001, Portugal, [email protected] Pedro Ferreira, Heinz College and Department of Engineering and Public Policy, Carnegie Mellon University, 5000 Forbes Avenue, Pittsburgh, PA 15213, USA, [email protected] João Paulo Costeira, Instituto Superior Técnico, University of Lisbon, Av. Rovisco Pais, Lisbon 1049-001, Portugal, [email protected] Abstract Understanding adoption patterns of smartphones is of vital importance to telecommunication managers in today’s highly dynamic mobile markets. In this paper, we leverage the network structure and specific position of each individual in the social network to account for and measure the potential heterogeneous role of peer influence in the adoption of the iPhone 3G. We introduce the idea of core- periphery as a meso-level organizational principle to study the social network, which complements the use of centrality measures derived from either global network properties (macro-level) or from each individual's local social neighbourhood (micro-level). Using millions of call detailed records from a mobile network operator in one country for a period of eleven months, we identify overlapping social communities as well as core and periphery individuals in the network. Our empirical analysis shows that core users exert more influence on periphery users than vice versa. Our findings provide important insights to help identify influential members in the social network, which is potentially useful to design optimal targeting strategies to improve current network-based marketing practices. -

Mobile Leapfrogging and Digital Divide Policy Assessing the Limitations of Mobile Internet Access
New America Foundation Mobile Leapfrogging and Digital Divide Policy Assessing the limitations of mobile Internet access By Philip M. Napoli and Jonathan A. Obar1 April 2013 This paper examines the emerging global phenomenon of mobile leapfrogging in Internet access. Leapfrogging refers to the process in which new Internet users are obtaining access by mobile devices and are skipping the traditional means of access: personal computers. This leapfrogging of PC-based Internet access has been hailed in many quarters as an important means of rapidly and inexpensively reducing the gap in Internet access between developed and developing nations, thereby reducing the need for policy interventions to address this persistent digital divide. This paper offers a critical perspective on the process of mobile leapfrogging. Drawing upon data on Internet access and device penetration from 34 countries, this paper first shows that while greater access to mobile technologies suggests the possibility of a leapfrog effect, the lack of 3G adoption suggests that mobile phones are not yet acting as functionally equivalent substitutes for personal computers. Next, this paper puts forth a set of concerns regarding the limitations and potential shortcomings of mobile-based Internet access relative to traditional PC-based Internet access. This paper illustrates a number of important relative shortcomings in terms of memory and speed, content availability, network architecture, and patterns of information seeking and content creation amongst users. This paper concludes that policymakers should be cautions about promoting mobile access as a solution to the digital divide, and undertake policy reforms that ensure that communities that rely on mobile as their only gateway to the Internet do not get left further behind.
