Network and Domain Autoconfiguration: A Unified Approach for Large Dynamic Networks
Only limited progress has been made in automating the configuration of routers, servers, and network topology. The authors propose the first unified attempt to combine both self-configuration of much of the host, router, and server information with automatic generation and maintenance of hierarchy under the same algorithmic framework. Testbed implementations show the approach is practical, while simulations reveal its scalability, rapidity, and efficiency with respect to network performance.

The authors explore the use and adaptation of well established VPN technologies to dynamically network at run time devices and services in personal networks. Virtual personal overlay networks are envisaged as an extension of the basic VPN concept to network PN nodes in a secure manner.
Wajdi Louati and Djamal Zeghlache, Institut National des TélécommunicationsOn the Design of a Self-Managed Wireless Sensor Network
During the last decade, there was a great technological advance in the development of smart sensors, low-power processors, and wireless communication protocols that when put together create a wireless sensor network (WSN). Smart, autonomous, and self-aware: that is the ultimate vision for WSNs. The success of this vision depends fundamentally on the self-management solutions.

Digital RF Processing: Toward Low-Cost Reconfigurable Radios
The authors review fundamental techniques recently developed that migrate RF and analog design complexity to the digital domain for a wireless RF transceiver.
Khurram Muhammad, Robert Bogdan Staszewski, and Dirk Leipold, Texas InstrumentsSystem Design Considerations for Ultra-Wideband Communication
The authors discuss issues associated with high-data-rate pulsed ultra-wideband system design, including the baseband processing, transmitter, antenna, receiver, and analog-to-digital conversion.

VLSI realization of video compression is the key to many real-time multimedia communications systems. The newly established MPEG-4 and, in particular, H.264 standards have become increasingly popular. However, the high coding efficiency of such video coding algorithms comes at the cost of a dramatic increase in complexity.
