... The ability to automatically adjust all aspects of the user's computing, communication, and storage functionality In a transparent and integrated fashion is the essence of a nomadic environment. Some of the key system parameters of concern include bandwidth, latency, reliability, error rate, delay, storage, processing power, interference, version control, file synchronization, access to services, ~nteroperability, and user interface.

... locations without being connected directly into the wheeling network and it allows the nomad to communicate while traveling. Although He bandwidth offered by wireless communication media varies over as enormous a range as does the w~reline network bandwidth, the nature of the error rate, fading behavior, interference level, and mobility issues for wireless are considerably different, so that the Algonquins and protocols require some new and different forms from those of Reline networks (Katz, 1994~.

... This section addresses mainly He network aIgori~m issues and does not focus on He many over issues involved with radio design, hardware design, tools for CAD, system drivers, and so on. What is important is that the network aigori~ms must be supported by the underlying radio (e.g., to provide signal-to-'nterference ratios, ability to do power control, change codes in CDMA environments, and the like)
