The Networks Laboratory
is directed by Dr. Brian L. Mark of the Dept. of Electrical and
Computer Engineering. Our research interests lie in the design, modeling, analysis,
and performance evaluation of networks, primarily communication networks. The
nature of the research may involve development of theoretical results, algorithm
design, numerical computation, computer simulation, hardware and/or software
development, or some combination of the above, depending on the particular research topic.
Our major focus is on the design, architecture,
and performance of communication networks, encompassing wireline, wireless networks,
and heterogeneous networks. We are interested in all aspects of network architecture
from the physical layer to the application layer. The main purpose of a
communication network is to allow multiple users to communicate
reliably, efficiently, and securely with one another. Networks of
the future will be expected to support a variety of applications and
media with differing service requirements. As a subject of
research, the complexity and breadth of communication networks
offers many challenges. Research on communication networks draws on many other
areas including communications theory, computer science, optimization theory, signal
processing, and systems theory. Important research questions of general
- How should the network be architected and designed?
- What is the capacity of the network?
- How can we evaluate the performance of the network?
- How can the resources of the network be managed or controlled to improve performance?
- What methodologies or algorithms can be developed to improve network performance?
- How can the network be made more secure?
- What are the network design tradeoffs among performance, reliability, security,and efficiency?
Specific research areas that are currently being pursued within the lab include:
- Estimation and control of communication networks
- Performance modeling of communication networks
- Dynamic spectrum management in cognitive radio networks
Other research areas that have been investigated in recent years within the lab
- Handoff algorithms for cellular networks
- Fast simulation of large queueing networks
- Localization and mobility management in wireless networks
- Security and quality-of-service integration in ad hoc networks
- High-speed switch and router architectures
- Packet filters for DDoS (Distributed Denial-of-Service) mitigation based on
network processor technology
