I am working as an assistant professor at the UCD School of Electrical and Electronic Engineering, which is attached to its BDIC program. This position will allow me to conduct teaching activities at BDIC, Beijing.

I am working as a Lecturer/assistant professor at the School of Electrical and Electronic Engineering, University College Dublin, Ireland. I am in charge of the Wireless Communications and Digital Communications modules. Currently focusing on federated learning security-based research and expanding on the technologies surrounding the 6G technology. Further, I am managing the CONFIDENTIAL-6G project from the UCD end.

Pasika Ranaweera has been a post-doctoral researcher in the School of Computer Science, University College Dublin, Ireland, since February 2023. He is the project manager of the CONFIDENTIAL-6G project, funded by the EU H2022-SNS grant ID: 101096435. He obtained his Bachelor's degree in Electrical and Information Engineering from the Faculty of Engineering, University of Ruhuna, Sri Lanka, in 2010 with honors and received the Lanekassen scholarship for pursuing a Master’s Degree in ICT in 2013 from the University of Agder, Norway. Pasika completed his Ph.D. from UCD, Ireland, on improving the security of service migrations of MEC in 2023. Prior to his Ph.D., he served as a lecturer attached to the Department of Electrical and Information Engineering, Faculty of Engineering, University of Ruhuna, Sri Lanka, from 2014 to 2018. Pasika is experienced in conducting teaching/ instructing/ demonstration work at international universities (UCD-Ireland, BDIC-China). He is currently conducting collaborative research with researchers at IIT-India, the University of Oulu-Finland, and the University of Ruhuna-Sri Lanka. He is a member of the NetSLab, PEL, and CONNECT research groups based at UCD. Pasika is focused on enhancing the security measures in 5G and beyond 5G mobile networks, while his main research focus is directed at Federated Learning-based security issues and how to overcome them utilizing Blockchain. His additional research directives extend to lightweight security protocols, formal verification, security, service quality optimization, 5G and MEC integration technologies (SDN, NFV, Blockchain), privacy preservation techniques, and IoT security. In addition to the research work, he serves as a reviewer for IEEE IoT journal, IEEE Access, IEEE Communication Magazine, IEEE IoT Magazine, SN Computer Science, and various IEEE-hosted conferences and workshops under the IEEE Communication Society (also a member of IEEE ComSoc).

IoT and 5G are emerging technologies that envisage a mobile service platforms capable of provisioning billions of communication devices which enable ubiquitous computing and ambient intelligence. These novel approaches are guaranteeing gigabit-level bandwidth, ultra-low latency and ultra-high storage capacity for their subscribers. The centralized nature of the conventional IoT architecture (cloud computing based) however, raises concerns over the latency and responsiveness of the services among other factors of reliability, security, and locational unawareness. To overcome these limitations, ETSI has introduced the paradigm of MEC for creating efficient data processing architecture extending the cloud computing capabilities in the RAN. The key idea of the MEC paradigm is to migrate the storage and processing infrastructure to the edge of the mobile network (preferably to a mobile BS or eNodeB) as other edge computing paradigms. The infrastructure is developed utilizing virtualization technologies capable of dynamic resource provisioning as in Virtual Machines (VMs). The integration of MEC with IoT technologies however, raises intricacies due to heterogeneity. Thus, interoperability and compatibility of diverse technologies interfacing with the MEC system results in security concerns worth investigating. Moreover, privacy is a salient predicament that gained recognition as a major requisite with the GDPR initiative for modern IT related services. Therefore, security and privacy are vital factors to be contemplated for realizing the feasibility of MEC paradigm.
