Mobile ad hoc social networks are selfconfiguring social networks that connect users using mobile devices, such as laptops, PDAs, and cellular phones. These social networks facilitate users to form virtual communities of similar interests or commonalities. This paper proposes semantics-based mobile social network (SMSN), a novel framework of a fully functional mobile ad hoc social network that ...

Boost power converters have been widely used for Power Factor Correction (PFC) in AC-DC conversions [1] and for power management in battery powered DC-DC conversions [2]. Moving beyond low-power applications, such as cellular phones, smart phones and other portable electronic products, boost converters are being used more and more in medium-power applications. For example, in computing and cons...

This study investigates the effect of cell phones on economic development and growth by performing an econometric analysis using data from the International Telecommunications Union and the Penn World Table. It discusses the various ways cell phones can make markets more efficient and how the diffusion of information and knowledge plays into development. Several approaches (OLS, Fixed Effects, ...

Real-time video capture and communication is expected to be an important function in many urban sensor networks composed of camera-equipped mobile phones. In this paper, we present AnySense, a network architecture that supports video communication between 3G phones and Internet hosts in urban sensing applications. AnySense implements transcoding of video streams between the Internet and circuit...

Often, it has been observed that telecommunication infrastructure development and economic growth proceed together. While this relationship has been studied in the context of developed (OECD) countries, in this study, we investigate this simultaneous relationship between telecommunications and the economic growth, using data for developing countries. Using 3SLS, we estimate a system of equation...

4G will not facilitate the design of cell phones. Compared to today's 3G, future 4G multistandard, multi-band cellular phones have to cover an increasing number of wireless standards. These standards include GSM, CDMA, WCDMA, 3GPP LTE/4G, WIMAX and even MIMO WIMAX AND MIMO LTE/4G at up to 25 frequency bands, and includes connectivity systems like WLAN and Bluetooth, and support navigation syste...

Along with the explosive growth of smart phones, a new wave of the mobile device development is on the way, in which the WiFi enabled cellular phone has been taking an extremely important position. Unlike the desk top PC and notebook computers, integrating the WiFi radio within a cellular phone is much more complicated and challenging than simply putting two systems in a box with the form facto...
