Dr Shiva Raj Pokhrel is a Lecturer of Mobile Computing. He received the B.E./M.E. ICT Engineering degree from Pokhara University, Nepal and PhD ICT Engineering degree from Swinburne University of Technology, Australia. He was a research fellow at the University of Melbourne (2017-2018) and a network engineer at Nepal Telecom (2007-2014). His research interests include federated learning, industry 4.0, blockchain modelling, optimization, recommender systems, 6G, cloud computing, dynamics control, Internet of Things and cyber-physical systems as well as their applications in smart manufacturing, autonomous vehicles and cities. He serves/served as the Workshop Chair/Publicity Co-Chair for several IEEE/ACM conferences including IEEE INFOCOM, IEEE GLOBECOM, IEEE ICC, ACM MobiCom, and more. He was a recipient of the prestigious Marie Curie Fellowship in 2017.

Small satellites have tight constraints on the size, weight, and power (SWaP) of the onboard electronics. This imposes challenges on the two dominant methods for implementing Inter-Satellite Links (ISLs), namely radio frequency (RF) and free space optical (FSO) communications. Next-generation solutions using visible light communications (VLC) and light emitting diodes (LEDs) have been proposed in the literatures. LED technology has advantages over its counterparts because of its low power consumption and lightweight. This talk will give a brief overview of the latest development.

Massive satellite constellations are currently being deployed in an unprecedented pace aiming to provide an integrated global coverage. In order to design and optimize such networks, it is important to perform both rapid and in-depth evaluations of their performance based on given design parameters. This presentation will provide an overview of the recent challenges and opportunities offered by mega satellite constellations and will explain the suitable performance analysis methods for these massive communication networks. It will present the main constellation models used in practical applications and further introduce theoretical models based on stochastic geometry that facilitate analytic solutions. The presentation then provides modeling examples for obtaining the statistics of satellites' pass duration, handover behavior, and both the downlink and uplink coverage performance.

Jinho Choi (Senior Member, IEEE) was born in Seoul, South Korea. He received the B.E. degree (magna cum laude) in electronics engineering from Sogang University, Seoul, in 1989, and the M.S.E. and Ph.D. degrees in electrical engineering from the Korea Advanced Institute of Science and Technology (KAIST), in 1991 and 1994, respectively. He is currently with the School of Information Technology, Burwood, Deakin University, Australia, as a Professor. Prior to joining Deakin, he was at Swansea University, U.K., as a Professor/Chair in wireless, in 2018, and the Gwangju Institute of Science and Technology (GIST), South Korea, as a Professor. He has authored two books published by Cambridge University Press in 2006 and 2010. His research interests include the Internet of Things (IoT), wireless communications, and statistical signal processing. He received a number of best paper awards including the 1999 Best Paper Award for Signal Processing from EURASIP. He is on the list of World’s Top 2% Scientists by Stanford University, from 2020 to 2021. He is currently an Editor of IEEE WIRELESS COMMUNICATIONS LETTERS and a Division Editor of Journal of Communications and Networks (JCN). He has also served as an Associate Editor or Editor of other journals including IEEE TRANSACTIONS ON COMMUNICATIONS, IEEE COMMUNICATIONS LETTERS, JCN, IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, and ETRI Journal.
