To meet the needs of diverse and massive communication services, deploying service function chains to flexibly combine virtual resources has become crucial. This paper proposes an optimization method based on fit entropy and network utility to address the limited communication network resources in medium\u2013low-voltage smart distribution grids. This was conducted by modeling the distribution grid as a three-domain model consisting of a service domain, a logical domain, and a physical domain and transforming it into a hierarchical bipartite hypergraph-matching problem, which is a complex combinatorial optimization problem. This paper introduces two matching optimization algorithms: \u201cbusiness domain\u2013logic domain\u2013physical domain integration\u201d and \u201cservice domain\u2013logic domain, logic domain\u2013physical domain two-stage\u201d, which effectively address this problem based on fit entropy and utility. The simulation results demonstrate that these algorithms significantly improve service success rates and resource utilization, enhancing overall network utility.<\/jats:p>","DOI":"10.3390\/s24175522","type":"journal-article","created":{"date-parts":[[2024,8,26]],"date-time":"2024-08-26T10:01:51Z","timestamp":1724666511000},"page":"5522","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Fit Entropy-Based Dynamic Communication Resource Slicing-Optimization Method in Smart Distribution Grids on the Medium\u2013Low-Voltage Side"],"prefix":"10.3390","volume":"24","author":[{"given":"Haiming","family":"Li","sequence":"first","affiliation":[{"name":"College of Telecommunications and Information Engineering, Nanjing University of Posts and Telecommunications, Nanjing 210003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaorong","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Telecommunications and Information Engineering, Nanjing University of Posts and Telecommunications, Nanjing 210003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jin, W., Yu, P., Xiong, A., Zhang, Q., Jin, D., Zhang, G., and Wang, Y.
