Research

The Systems group is focused on quality research of emerging technologies.

Research domains

The following research areas are covered:

Mobile Platforms
Multipath TCP
Network Architectures
Network Security
Operating Systems
Peer-to-Peer Systems
Wireless Sensor Networks

Mobile Platforms

Mobile devices have become ubiquitous, as smartphones have evolved from phones with a few pre-loaded applications to true application platforms. Mobile devices raise several development challenges, such as power consumption, application connectivity, and reduced screen real-estate.

Research tries to tackle these challenges by leveraging operating system features, designing new and improved algorithms for resource management, using the latest technologies for interconnecting devices.

Multipath TCP

Multipath transport, as defined by RFC 6182, aims to realize some of the goals of resource pooling by simultaneously making use of multiple disjoint (or partially disjoint) paths across a network.  The two key benefits of multipath transport are the following:

  • To increase the resilience of the connectivity by providing multiple paths, protecting end hosts from the failure of one.
  • To increase the efficiency of the resource usage, and thus increase the network capacity available to end hosts.

Costin Raiciu is principal investigator in Trilogy 2 FP7 project, funded by the EC.

Network Architectures

Network architecture refers to specifying the network physical components, their functionality and organization, as well as their operational principles and procedures in order to provide support for delivering a communication service.

The research focuses on designing, implementing, optimizing and evaluating communication networks. Research covers all network communication layers, taking into consideration both the hardware and software solutions required for building a communication network.

Network Security

Network Security covers all security aspects of computer networks, ranging from network infrastructure deployment to authentication services.

Research focuses on improving all network security aspects, such as authentication protocols, intrusion detection and prevention systems and network device configurations.

Operating Systems

Operating Systems are at the heart of every computing device. The explosion of mobile devices has led to the advance of the Operating Systems domain, the new platforms being targeted leading to multiple improvements.

Research in this domain focuses on designing new features to take advantage of the new platforms and improving resource management.

Peer-to-Peer Systems

Peer-to-Peer systems consist of entities called peers participating in a network, sharing their resources in the system for all to benefit. Challenges in the Peer-to-Peer systems consist of dealing with rogue peers, differentiated participation, high peer churn, resource availability etc.

In order to solve these challenges, research has focused on developing and testing new architectures for resource sharing, new communication protocols, extending current clients and evaluating new and efficient ways of peer interaction.

Wireless Sensor Networks

A Wireless Sensor Network (WSN) consists of a large number of sensor devices characterized by reduced dimension, low cost and low power, which are able to organize themselves into a network by communicating through a wireless medium, collaborating in order to accomplish a common task.

The network design objectives and requirements include: reduced dimension, low cost and low power, scalability, adaptability, reliability, fault-tolerance, security, selfconfigurability and QoS. Research in this domain focuses on: security mechanisms, trust and reputation models, routing protocols, simulation tools.

Projects

The group is involved in European projects such as P2PNext and TWISNet.

Several projects are being developed in collaboration with companies: Ixia, VirtualMetrix, Intel.
