Towards Decentralized Task Offloading and Resource Allocation in User-Centric Mobile Edge Computing

1 code implementation3 Dec 2023 Langtian Qin, Hancheng Lu, Yuang Chen, Baolin Chong, Feng Wu

In the traditional cellular-based mobile edge computing (MEC), users at the edge of the cell are prone to suffer severe inter-cell interference and signal attenuation, leading to low throughput even transmission interruptions.

Joint Optimization of Base Station Clustering and Service Caching in User-Centric MEC

1 code implementation21 Feb 2023 Langtian Qin, Hancheng Lu, Yao Lu, Chenwu Zhang, Feng Wu

To address single-base station (BS) transmission limitation and serious edge effect in traditional cellular-based edge service caching networks, in this paper, we proposed a novel user-centric edge service caching framework where each user is jointly provided with edge caching and wireless transmission services by a specific BS cluster instead of a single BS.
