Performance analysis of local exit for distributed deep neural networks over cloud and edge computing
Autor: Changsik Lee, Seungwoo Hong, Sungback Hong, Taeyeon Kim
Publikováno v: ETRI Journal, Vol 42, Iss 5, Pp 658-668 (2020)
In edge computing, most procedures, including data collection, data processing, and service provision, are handled at edge nodes and not in the central cloud. This decreases the processing burden on the central cloud, enabling fast responses to end

Competition-based distributed BS power activation and user scheduling algorithm
Autor: Jihwan Kim, Eun Kyung Kim, Song Chong, Jeongho Kwak, Changsik Lee
Publikováno v: Journal of Communications and Networks. 19:41-50
Existing cellular technologies in unlicensed band such as license assisted access (LAA)-LTE do not capture inter-cell interference (ICI) management which becomes more important in modern small cell network environments. Moreover, existing ICI managem
