報(bào)告簡(jiǎn)介:
The Mobile Edge Computing (MEC) paradigm gives impetus to the vigorous advancement of Internet of Things (IoT), through provisioning low-latency computing services at the edge of core networks. We consider AoI-aware query services in an MEC network empowered by digital twin technology for diverse IoT applications. We formulate a novel minimization problem that explores non-trivial trades-off between these two conflicting optimization objectives. We then propose an approximation algorithm with a provable approximation ratio for the problem. We finally evaluate the performance of the proposed algorithms via simulations.
