Research
The research of the Communication Networks and Systems laboratory covers five areas:
Internet traffic management
In the traffic management area we conduct research to enhance the performance and utilization of the networks that the Internet builds on. Important topics are traffic characterization, performance optimization, network management and network monitoring. Current projects in the area are 4WARD and CNS. For more information see the traffic management web pages.
The Network of the Future
Contact: Bengt Ahlgren
Our research in the communication architectures area deals with issues that are related to how communication protocols and network interaction work together in an increasingly dynamic communication environment. Specific research issues are naming and addressing on a global scale, integration of caching in the network infrastructure, and mechanisms for handling mobility and intermittent connectivity.
Current projects: SAIL and NetInf (a CNS project).
Some past projects: 4WARD, NordicHIP, and Nwarch (a CNS project).
Communication in multi-hop wireless networks
We do research on a broad range of topics in communication in
multi-hop wireless networks, including ad hoc networks and embedded
systems, WLAN's and spontaneous networks. In particular, our work
addresses the challenges posed by the limited network capacity and
battery resources in these networks, as well as their decentralized
operation.
Current projects: Winternet, RUNES
Support for real-time media communication
Contact: Ian Marsh
Our research in supporting real-time media is networking centric with an eye on the quality needs for the applications and users. Only by considering the applications needs with the performance of the network can achievable quality media be delivered. Currenly we have studied real-time telephony and its needs, but higher dimensionality audio will be addressed.
Networked small systems
Contact: Bengt Ahlgren, Laura Feeney
Our research on support for small systems focuses on a number of issues associated with sensor networking. We are particularly interested in energy efficient communication protocols for sensor network, as well as deployment issues surrounding questions of addressing and identity in sensor networks and interactions between co-located sensor networks. Much of this work is done in the context of Wisenet, the Uppsala VINN Excellence Center for Wireless Sensor Networks.
Current projects: WISENET
