Dr Ivan Ho

Dr Ho’s group has extensive research experience in vehicular networks and connected vehicles. The Internet of vehicles is a very special type of Internet of things. To accurately model the performance of vehicular networks, Dr Ho and his group need to characterize vehicular mobility and connectivity correctly. The team has developed methodologies for modeling the transmission performance of vehicular ad-hoc networks (VANET) based on heterogeneous vehicle distribution. Given basic traffic information, such as velocity and traffic control signals, the throughput and delay performance of the vehicular network can be readily computed as a dynamic function of space and time, which lays the foundation for future studies and applications of vehicle-to-everything (V2X) communications and networking.

In addition, with the increasing popularity of inter-vehicle communications and the development of new protocol standards, the roads will likely be filled with high-speed wireless users in the near future. To exploit interference in high-dense vehicular networks, Dr Ho and his group studied non-orthogonal data exchange among vehicles. Specifically, with the use of physical-layer network coding and multiuser detection techniques for data communications. For connected autonomous vehicles, the group has also addressed the problem of efficient 3D road map data dissemination through developing a number of techniques based on index coding, opportunistic scheduling, and hashing.

Other than vehicular networks, Dr Ho and his group is also active in the development of IoT applications. He primarily invented the MeshRanger series wireless mesh embedded system, which won Silver Award in Best Ubiquitous Networking at the Hong Kong ICT Awards 2012. His work on indoor positioning also received Gold Medal at the International Trade Fair Ideas and Inventions New Products (iENA) in Germany in 2019. Dr Ho served/is serving as an associate editor for IEEE Access and IEEE Transactions on Circuits and Systems II, and the TPC Co-chair for the PERSIST-IoT Workshops in conjunction with ACM MobiHoc 2019 and IEEE INFOCOM 2020.
