Protocol Engineering Laboratory (PEL)

28 West Delaware Ave, Professor Paul Amer.

The PEL is dedicated to the research, development, and improvement of new and existing computer network protocols. PEL researchers currently are investigating innovative transport protocol alternatives to TCP and UDP, such as the SCTP (stream control transport protocol) and MPTCP (multipath TCP), emphasizing their use within army mobile ad-hoc networks, and Google's SPDY protocol for faster web surfing.

DEGAS Networking Laboratory

214 Smith Hall, Professor Chien-Chung Shen.

The DEGAS (Distributed, EnerGy conscious, Ad hoc and Sensor/Space) Networking Laboratory pursues advanced research in mobile wireless networks. Research areas include mobile ad hoc networks, wireless sensor networks, wireless mesh networks, dynamic spectrum access networks, underwater acoustic networks, and ad hoc airborne networks, energy-aware protocols, and mobile cloud computing.

Network Management and Optimization Laboratory

342 Smith Hall, Professors Adarsh Sethi and Errol Lloyd.

Network management involves the design of techniques for the monitoring and control of computer networks to ensure optimal performance and resource utilization. We focus on fault management whose aim is to detect, diagnose, localize, and recover from hardware and software failures and performance bottlenecks that may plague a network. We are also interested in the management of wireless networks including methods for managing mobility to provide seamless operation of network services.

In network optimization we aim to provide provably optimal or near optimal solutions to a range of power specification and control problems arising in wireless ad hoc and sensor networks. The primary focus is on topology control (assigning power levels to network nodes so as to achieve a specified network topology) in both stationary and mobile networks. Additional work includes the study of relay node placement and of power back off as a collision resolution mechanism.
