IoT Communications and Networking


Program Leader: Prof. Eryk Dutkiewicz 

This program focuses on enabling technologies for IoT/5G communications and networking, including, large scale, energy efficient, and secure IoT networking, spectrum sensing and sharing, mission critical communications with ultra low latency and high reliability, flexible network management, network timing/synchronisation, and operation. Our research attracts generous support from our partners and sponsors, including Australian Research Council, Intel, US army research office, with output ranging from patents, research papers, prototypes, demos, software/tools, to international standard contributions. Current research activities include:

-Spectrum sharing, IoT/5G, and green communications
-Network and wireless (IoT) security
-Software-defined networking
-MIMO, mmWave, and full-duplex communications 

The program has access to state of the art RF, IoT and networking labs. It is supported by 7 academics and 17 PhD students.


5G and IoT Laboratory

To meet the requirements of 5G more spectral resources below 6 GHz are required. In this regard, we focus on developing spectrum sharing based solutions for effective detection of incumbents, interference mitigation, multi radio access technology coexistence, dynamic construction of radio environment maps to enable spectrum sharing and economics driven spectrum auctioning schemes. We have a well establish portfolio working closely with industry on international standardisation efforts - Spectrum Access System (US) and Licensed Shared Access (Europe).

We also work on MAC layer techniques for machine type communications in IoT. We focus on modelling and analysing the impact on massive number of devices, ultra-reliable communications and low latency communications.


SDN Laboratory

It is believed that 5G would be driven by a SDN core and would consist of edge networking elements (such as basestations) which would be software controlled. We have established a state of art SDN lab to conduct research in various areas. Together with 9 other Universities, CSIRO and AARNET, we have developed a wide area SDN test-bed for development and prototyping of future SDN solutions.

Our research and development in SDN is threefold:

  1. Architecture, protocol and algorithm development for Wired and Wireless SDN (WSDN).
  2. Performance investigation, analysis and modelling for SDN and WSDN.
  3. Software development and prototyping of SDN applications, SDN Controllers and Network Function Virtualisation (NFV). 


Network Security Laboratory

Network-borne malicious software and attacks are threating to undermine the digital economy. The Network Security Laboratory is developing cyber defence solutions to secure the Internet, the cloud, as well as the Internet of Things (IoT).

In particular, we revealed the inherent behaviour of virus propagation and network curing processes through Markov analysis. Our Intrusion Detection techniques have achieved high fidelity detection of Denial of Service (DoS) attacks by applying patter recognition procedures. We have designed security policy and access control schemes to provide secure and efficient data management and sharing.


Network Timing Laboratory

Advancements in timekeeping led to the discovery of the new world and the development of GPS. The Network Timing Laboratory is working to establish the foundations of, and trial, the next timing frontier: a system for the trusted synchronisation of computer clocks over the Internet. It will contribute to planetary infrastructure by leading the replacement of the existing system which is inaccurate, unreliable, insecure, and will collapse under the load of the Internet of Things.
