• My research is in the general areas of computer networks and wireless communications. I study next-generation wireless/mobile multihop network technologies, non-terrestrial networks, multimedia networks, IoT networks, resource utilisation, QoS/QoE, multicasts, network security, mobility management, and parallel and distributed systems. In these areas, I design algorithms/protocols, conduct performance analysis, and develop theoretical analysis.
