Division Contact: David Su Networking for Pervasive Computing We are working with industry to promote the development of cost-effective, interoperable, and secure protocols for dynamically discovering and automatically configuring distributed network services in mobile computing environments. Our research projects include modeling the performance of picocellular wireless channels and evaluating the performance effects of interference among different medium access control protocols that share unlicensed wireless spectrum. Research projects also include characterizing and comparing the technical capabilities of emerging protocols for automatic discovery and configuration of network devices and services, and assessing the scalability of dynamic service discovery protocols. Contact: Doug Montgomery We are working to remove barriers to the next generation of reliable and secure Internet-working technologies and multimedia network services. The focus of our research is on test methods and reference implementations for next-generation Internet-working technologies; interoperability among next-generation Internet-working products; and measurement techniques and performance characterizations for network services that integrate voice, video, and data. Research projects include investigating changes to the Internet architecture that will support guaranteed bandwidth and other quality of services for real-time applications, such as audio, video, and synchronized data. This project focuses on the scalability of the proposed enhancements, interoperability issues, and methods and metrics to characterize the digital data streams. Research projects also include evaluating the performance of techniques for securing the next-generation Internet and investigating strategies to incrementally deploy next-generation, Internet-working technologies. Contact: Doug Montgomery We are working with industry to develop signaling protocols for integrating electro-optical and all-optical high bandwidth networks. Our goal is to expedite the development and deployment of high-speed, interoperable communications systems and services. Research projects include network simulation and modeling of integrated optical and electronic networks, comparing and contrasting competing technical proposals for signaling in multiprotocol lambda switching systems, and modeling and evaluating algorithms for fault-detection and recovery in wave-division multiplexing networks. Contact: David Su We are working with industry to promote the development of cost-effective, interoperable, wireless technologies that can support multimedia data transmission and that can operate in highly mobile, power-constrained environments. Research projects include characterizing difficult wireless transmission channels in high frequency ranges and evaluating competing proposals for medium access control in high bandwidth wireless systems. Research projects also include investigating techniques to effectively transmit video data over mobile wireless communication channels, and evaluating proposed protocols for routing in mobile ad hoc networks.
