A Mobile Ad Hoc Networking Competition: A Retrospective Look at the MANIAC Challenge

This article describes the Mobile Ad Hoc Networking Interoperability and Cooperation (MANIAC) Challenge, a competition in MANETs. The primary objective of the competition was to assess the trade-offs between network-wide connectivity and resource utilization in a MANET comprising autonomous self-interested nodes. The competition attracted participants from academic institutions in the United States, Europe, and Africa. The data collected provide a better understanding of link stability, route effectiveness, cooperation, and competition in an autonomously deployed MANET.

Mobile goes global: The effect of cell phones on economic growth and development

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 andknowledge plays into development. Several approaches (OLS, Fixed Effects, 2SLS) were used to test over 20 econometric models. Overall, the mobile cellular subscriptions rate was found to have a positive and significant impact on countries’ level of real per capitaGDP and GDP growth rate. Furthermore, the study provides policy implications for the use of technology to promote global growth.
