Dr. Madhusanka Liyanage (Senior Member, IEEE) received his B.Sc. degree (First Class Honours) in electronics and telecommunication engineering from the University of Moratuwa, Moratuwa, Sri Lanka, in 2009, the M.Eng. degree from the Asian Institute of Technology, Bangkok, Thailand, in 2011, the M.Sc. degree from the University of Nice Sophia Antipolis, Nice, France, in 2011, and the Doctor of Technology degree in communication engineering from the University of Oulu, Oulu, Finland, in 2016. From 2011 to 2012, he worked as a Research Scientist at the I3S Laboratory and Inria, Sophia Antipolis, France. He is currently an assistant professor/Ad Astra Fellow at the School of Computer Science, University College Dublin, Ireland. He is also acting as an adjunct Processor at the Center for Wireless Communications, University of Oulu, Finland. He was also a recipient of the prestigious Marie Skłodowska-Curie Actions Individual Fellowship during 2018-2020. During 2015-2018, he has been a Visiting Research Fellow at the CSIRO, Australia, the Infolabs21, Lancaster University, U.K., Computer Science and Engineering, The University of New South Wales, Australia, School of IT, University of Sydney, Australia, LIP6, Sorbonne University, France and Computer Science and Engineering, The University of Oxford, U.K. He is also a senior member of IEEE.

In 2020, he received the “2020 IEEE ComSoc Outstanding Young Researcher” award by IEEE ComSoc EMEA. Dr. Liyanage’s research interests are 5G/6G, SDN, IoT, Blockchain, MEC, mobile, and virtual network security.  More info:

Blockchain is emerging as one of the most industry-disrupting technologies and has been well embraced by the telecommunication community. The technology is composed of timestamped and cryptographically sealed sets of tamper-proof records of transactions (aka blocks), which are shared and synchronized among the members of the blockchain P2P network. Simultaneously, P5GN is an evolving paradigm in the telecommunication world that has the potential to cater to the specific and local/contextual needs of the industry verticals, including smart cities, smart healthcare, IIoT, and autonomous vehicles. Nonetheless, there are numerous impediments on the way towards the realization of fully functional P5GNs. Some of these issues are spectrum and infrastructure scarcity, roaming frauds, security vulnerabilities, network functions, and data management. To mitigate the mentioned issues in a secure, decentralized, and trustless manner, blockchains and smart contracts can be leveraged. Thus, this talk will focus on the multifarious use of blockchain towards the P5GNs. It will also discuss various implementation challenges when using blockchain for P5GNs, along with possible solutions.
