چکیده
We developed an information delivery system, namely WIDE (Wireless Information Delivery Environment), in client-server architecture using 802.11b infrastructure. WIDE aims to deliver popular information services to registered mobile clients in WLAN hot spots. We present the proposed system architecture, related delivery mechanism and communication protocols. We also give a brief overview of mechanisms required for secure and reliable communication in WIDE system. Performance evaluation results of the proposed system using the implemented prototype are also included in this paper.

Detection of napropamide by microwave resonator sensor using carbon nanotube – polypyrrole- chitosan layer
This paper presents the design and fabrication of proximity coupled feed disk resonator coated with Multi Walled Carbon Nanotubes (MWCNTs) and Polypyrrole-Chitosan (PPy-CHI) layers as a napropamide sensor. Computer Simulation Technology (CST) microwave studio was used to obtain the best design of disk resonator and feed line position in 5 GHz resonant frequency. Also, MWCNTs - PPy-CHI layers we...
متن کاملLow Cost UAV-based Remote Sensing for Autonomous Wildlife Monitoring
In recent years, developments in unmanned aerial vehicles, lightweight on-board computers, and low-cost thermal imaging sensors offer a new opportunity for wildlife monitoring. In contrast with traditional methods now surveying endangered species to obtain population and location has become more cost-effective and least time-consuming. In this paper, a low-cost UAV-based remote sensing platform...
متن کاملA High Efficiency Low-Voltage Soft Switching DC–DC Converter for Portable Applications
This paper presents a novel control method to improve the efficiency of low-voltage DC-DC converters at light loads. Pulse Width Modulation (PWM) converters have poor efficiencies at light loads, while pulse frequency modulation (PFM) control is more efficient for the same cases. Switching losses constitute a major portion of the total power loss at light loads. To decrease the switching losses...

Rapid advances in technology have resulted in laptop (mobile) computers with performance and features comparable to desktop (stationary) machines. Advances in rechargeable battery technology have failed to keep pace, decreasing the usefulness of mobile computers and portable wireless devices. Several methods of power management can be used to prolong the battery life of a mobile computer. We pr...
متن کاملLessons Learned from the Design of a Mobile Multimedia System in the MOBY DICK Project
Recent advances in wireless networking technology and the exponential development of semiconductor technology have engendered a new paradigm of computing, called personal mobile computing or ubiquitous computing. This offers a vision of the future with a much richer and more exciting set of architecture research challenges than extrapolations of the current desktop architectures. In particular,...
