Network control and management for ultra-dense LEO satellite networks
With the rapid development of low earth orbit (LEO) satellites, the ultra-dense LEO satellite-terrestrial integrated networking has become a promising paradigm to provide wide coverage, high capacity, and flexible services for the sixth generation (6G) mobile communication networks. In this talk, an integration of medium earth orbit (MEO) satellites, LEO satellites, and satellite early stations (SESs) is introduced to implement seamless connectivity and high-speed data rate service. For service provision, the service data needs to go through a series of on-board processing, before being downloaded to the terrestrial network for further applications. To this end, service function chain (SFC), an ordered concatenation of network functions (NFs), is introduced to support service provision. By allocating the constituent NFs over the network, three efficient multiple service delivery schemes are proposed to minimize the overall delivery completion latency, while considering resource sharing and competition among multiple SFCs.

Network resource management for supporting digital twins with data age targets
Digital twins (DTs) are virtual implementations of physical systems (PSs) and can represent the states of the PSs in realtime. In order to update the DTs with changes in their corresponding PSs, the PSs should regularly send their state information data to the DTs. Each DT must be assigned to an execution server (ES) that processes the forwarded data from its corresponding PS. The output is then made available to applications that are operating at an internet cloud server. In this talk we consider the problem of DT placement and server time allocations such that the maximum data request-response delay experienced by the application over all PSs is minimized, subject to maximum data age target constraints at the DTs and the application server. The problem is first formulated as an integer quadratic program (IQP) and then transformed into a semidefinite program (SDP). The problem is NP-complete. Since exact polynomial solutions are unavailable, several practical polynomial-time approximation algorithms are introduced. The algorithms are designed to give solutions with different trade-offs between the accommodation of the application input timing latency and the achievement of data age targets.
