Objectives mHealth interventions for MNCH have been shown to improve uptake of antenatal and neonatal services in low- and middle-income countries (LMICs). However, little systematic analysis is available about their impact on infant health outcomes, such as reducing low birth weight or malnutrition among children under the age of five. The objective of this study is to determine if an age- and stage-based...
Mobile messaging has become a trend in our daily lives. The current schema for messaging is to route all the messages between mobile users through a centralized server. This scheme, though reliable, creates very heavy load on the server. It is possible for users to communicate through peer-to-peer (P2P) connection, especially over urban networks characterized by heavy user traffic and dense network...
The use of online messaging systems to exchange information has changed due to the ability to share text, video and pictures almost immediately. Also it has become an excellent alternative for transmitting data with certain reserve levels in places or where voice signals and other forms of communication are not of high quality and/or availability, creating gaps in critical information security systems...
In this paper, we extract the characteristics of WeChat traffic and propose approaches to identify WeChat traffic in cellular data network. WeChat communication mechanisms are discussed. The traffic and usage pattern of Video Call service provided by WeChat are studied from massive traffic data using Spark, differently from previous methods. We analyze the features of WeChat Video Call service, a...
Spam has been infesting our emails and Web experience for decades; distributing phishing scams, adult/dating scams, rogue security software, ransomware, money laundering and banking scams… the list goes on. Fortunately, in the last few years, user awareness has increased and email spam filters have become more effective, catching over 99% of spam. The downside is that spammers are constantly changing...
It is becoming clear that as mobile devices become more capable, the user interface is the last remaining barrier to the scope of applications and services that can be made available to the users of these devices. It is equally clear that speech has an important role to play in removing these user interface barriers. Vlingo, based in Boston, is a four-year-old company that creates multi-modal interfaces...
Data quality is a key factor in the successful application of customer relationship management (CRM) software, especially when the data is used for mobile real-time communication with customers. Based on information from literature, strategies and measures for data quality improvements have been selected, applied and evaluated during the introduction and operation of a mobile CRM platform for a major...
Mobile social networks are gaining popularity with the pervasive use of mobile phones and other handheld devices. In these networks, users maintain friendship links, exchange short messages and share content with one another. In this paper, we study the user behaviors in mobile messaging and friendship linking using the data collected from a large mobile social network service known as myGamma (m...
Current text messaging protocols over the world allow a rigid limit of 160 characters per SMS, using the default messaging system of the mobile. However this limit is often found to be too less under ordinary circumstances and very often, to communicate effectively, a concatenated message needs to be sent. This, coupled with exorbitant messaging rates adds to the reduced effectiveness and decrease...
It is well known that Information and Communication Technologies (ICT) improve productivity when they are combined to complementary inputs such as work process changes. However, it is not so well known, how these improvements are created and applied in a health care sector, because the performance of communication processes inside knowledge work has not been studied much. It has been said that a patient-focused...
Mobile, delay-tolerant, ad hoc and pocket-switched networks may form an important part of future ubiquitous computing environments. Understanding how to efficiently and effectively route information through such networks is an important research challenge, and much recent work has looked at detecting communities and cliques to determine forwarding paths. Such detected communities, however, may miss...
In this paper, we design and study the performance of a multiple access control (MAC) scheme for the multiplexing and the integrated delivery of voice, mobile messaging IP and H.264 videoconference traffic over a high-speed next-generation cellular TDMA channel with errors and capture. To the best of our knowledge, this is one of the first papers in the literature investigating the integration of...
The exponential growth of mobile messaging worldwide has made it an indispensable tool for social and business interactions. The interoperability between SMS (short messaging service) and IM (instant messaging) networks has enabled mobile users to communicate over the Internet seamlessly. However, the proliferation of cellular phones and handheld devices with messaging capability has also attracted...
