This book constitutes the thoroughly refereed post-proceedings of the International Conference on Information Networking, ICOIN 2003, held at Cheju Island, Korea in February 2003. The 100 revised full papers presented were carefully selected during two rounds of reviewing and revision. The papers are organized in topical sections on high-speed network technologies, enhanced Internet protocols, QoS in the Internet, mobile Internet, network security, network management, and network performance.

In 1945, Dr. Ernst Weber founded, and was the first Director of, the Microwave Research Institute (MRI) at Polytechnic University (at that time named the Polytechnic Institute of Brooklyn). MRI gained worldwide recognition in the 50s and 60s for its research in electromagnetic theory, antennas and radiation, network theory and microwave networks, microwave components, and devices. It was also known through its series of 24 topical symposia and the widely distributed hardbound MRI Symposium Proceedings. Rededicated as the Weber Research Institute (WRI) in 1986, the institute currently conducts research in such areas as electromagnetic propagation and antennas, ultrabroadband electromagnetics, pulse power, acoustics, gaseous electronics, plasma physics, solid-state materials, quantum electronics, electromagnetic launchers, and networks. Following MRI tradition, WRI has launched its own series of in-depth topical conferences with published proceedings. Previous conferences in this series were: Directions in Electromagnetic Wave Modeling; October 1990 Ultra-Wideband Short-Pulse Electromagnetics; October, 1992 Ultra-Wideband Short-Pulse Electromagnetics, II; October, 1994 The proceedings of these conferences were also published by Plenum Press. This volume constitutes the proceedings of the fourth WRI International Conference dealing with Guided-Wave Optoelectronics: Device Characterization, Analysis and Design. The conference was held October 26-28, 1994, at the Polytechnic University in Brooklyn, New York, in cooperation with the IEEE Lasers and Electro Optics Society, and with the Optical Society of America.

On September 10-13, 1990, the first international meeting on Microsystem Technologies takes place at the Berlin International Congress Center. Most of the traditional congresses deal with themes that become more and more specific, and only a small part of the scientific world is reflected. The Micro System Technologies is attempting to take the opposite direction: During the last two decades the development of microelectronics was characterized by a tremendous increase of complexity of integrated circuits. At the same time the fields of microoptics and micromechanics have been developed to an advanced state of the art by the application of thin film and semiconductor technologies. The trend of the future development is to increase the integration density by combining the microelectronic, microoptic, and micro mechanic aspects to new complex multifunctional systems, which are able to comprise sensors, actuators, analogue and digital circuits on the same chip or on multichip-modules. Microsystems will lead to extensions of the field of microelectronic applications with important technical alterations and can open new considerable markets. For the realization of economical solutions for microsystems a lot of interdisciplinary cooperation and know-how has to be developed. New materials for sensitive layers, substrates, conducting, semiconducting, or isolating thin films are the basis for the development of new technologies. The increasing complexity leads to increasing interaction among electrical and non-electrical quantities.
