Distributed Networking and Security

Distributed networking and security research group is working on two research areas, namely (a) energy aware computing and communications and (b) distributed systems and services.

Energy-aware computing and communications is a very timely and important topic. Energy consumption is a concern with today’s mobile devices. While the capabilities of the devices have improved rapidly over the last ten years transforming also the way these devices are being utilized, battery technology has not been able to keep up with this evolution. As a consequence, there is an increasing gap between the battery capacity and the amount of energy required for typical usage. In addition, reducing energy consumption and carbon footprint has been widely recognized as a challenge for the whole ICT industry. The growing operational expenditure in ICT calls for more energy-aware networking solutions throughout the entire end-to-end communication chain. We address these challenges by building models of energy consumption through experiments and measurements based on which we develop new more energy-efficient protocols and services.

Distributed systems and services address architectures, platforms, and protocols for flexible, scalable, and easily usable services. Cloud computing uses virtual resources in the Internet for computing and storage, and is able to elastically scale to match changing resource needs. Merging cloud technologies with mobile domain has potential to offer new technology innovations and business opportunities for operators, vendors, and developers, as well as novel services for end users. Mobile cloud computing provides versatile research topics varying from the virtualization layer up to the service layer. Machine-to-machine communication, wireless sensor networks, and peer-to-peer applications are other examples of active research areas in the distributed services domain.

We work in collaboration with the Mobile Computing Group, and the Networking Group at HIIT. Our international collaboration includes University of California at Berkeley in USA, Swedish Institute of Computer Science (SICS) in Sweden, Tsinghua University in China, Beijing University of Post and Telecommunications (BUPT) in China, Birla Institute of Technology and Science (BITS) in India among others.
