Internet Systems and Networks Security Research Group (ISNS)

The Internet Systems and Networks Security Research Group in the Department of Computer Science exists to research all aspects of networking and communicating systems, and address specific issues related to Internet and control, wireless sensor networks, network performance modelling and measurement, performance evaluation with Quality of Service (QoS) constraints and application performance investigation.

The work ranges from the underlying mathematical theory to practical creation and operation of networked systems.

Theories and technologies in networking, sensing, control and communication play important roles in the modern world and are expected to remain of great significance in the future.

Research strengths

The group has research strengths in Internet Control, Wireless Sensor Networks, Internet Quality of Service and Congestion Control, Coding Theory as well as in Accessibility and Usability.

The main research topics in our Networks and Control Research Group are as follows:

  • Control of Networks
  • Internet Control
  • Network Performance Measurement and Modelling
  • Wireless Sensor Networks
  • Accessibility and Usability
  • Semantic Interoperability
  • Coding Theory and Cryptography
  • QoS Provisioning and Enhancement in Heterogeneous Networks

The group has its own specialist lab facilities housed within the Haslegrave Building, which include: a multi-computer routing and Internet algorithm test network, wireless sensor network development platform, and two control systems rigs. The group has research strengths in Internet Control, Wireless Sensor Networks, Internet Quality of Service, Congestion Control and network performance measurement. Our research work has been mainly funded by EPSRC, TSB, MoD, BAE Systems and other funding bodies. Our industrial collaborators include BAE Systems, Jennic, Arqiva, Sure, Toyota, Sensinode and Rolls Royce et al.

Recent capital funding has extended the group's facilities to include a multirouter experimental facility for Networks Teaching and Research and a 500-node sensor network.

The group has entertained visitors from China, Portugal, Germany and Hungary.

The ISNS group runs a number of funded and research student projects.
