ABSTRACT
Mobile devices today boast processing power and memory on par with that found in desktop computers. Wireless connectivity has become much more readily available. Many metropolitan areas feature large-scale wireless networks and cellular or satellite connections are accessible in many remote areas. Furthermore, we are seeing a continuing decrease in the cost of hardware-the mobile devices themselves, as well as accessories, such as global positioning system (GPS) units. What was once a cost-prohibitive, underpowered, immature technology is now a reality.
