Current HM approaches based on a single criterion may lead to unnecessary and frequent handovers due to a partial network view that is constrained to information about link quality. In turn, HM approaches based on multicriteria may present a failure of handovers and wrong network selection, decreasing the throughput and increasing the packet loss in the network. This paper proposes SIM-Know, an approach for improving HM. SIM-Know improves HM by including a Semantic Information Model (SIM) that enables context-aware and multicriteria handover decisions. SIM-Know also introduces a SIM-based distributed Knowledge Base Profile (KBP) that provides local and global intelligence to make contextual and proactive handover decisions. We evaluated SIM-Know in an emulated wireless network. When the end-user device moves at low and moderate speeds, the results show that our approach outperforms the Signal Strong First (SSF, single criterion approach) and behaves similarly to the Analytic Hierarchy Process combined with the Technique for Order Preferences by Similarity to the Ideal Solution (AHP-TOPSIS, multicriteria approach) regarding the number of handovers and the number of throughput drops. SSF outperforms SIM-Know and AHP-TOPSIS regarding the handover latency metric because SSF runs a straightforward process for making handover decisions. At high speeds, SIM-Know outperforms SSF and AHP-TOPSIS regarding the number of handovers and the number of throughput drops and, further, improves the throughput, delay, jitter, and packet loss in the network. Considering the obtained results, we conclude that SIM-Know is a practical and attractive solution for cognitive HM.<\/jats:p>","DOI":"10.3390\/s21124234","type":"journal-article","created":{"date-parts":[[2021,6,21]],"date-time":"2021-06-21T04:21:21Z","timestamp":1624249281000},"page":"4234","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Semantic and Knowledge-Based Approach for Handover Management"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3695-3578","authenticated-orcid":false,"given":"Fulvio Yesid","family":"Vivas","sequence":"first","affiliation":[{"name":"Departamento de Telem\u00e1tica, Universidad del Cauca, Popay\u00e1n, Cauca 190002, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2223-947X","authenticated-orcid":false,"given":"Oscar Mauricio","family":"Caicedo","sequence":"additional","affiliation":[{"name":"Departamento de Telem\u00e1tica, Universidad del Cauca, Popay\u00e1n, Cauca 190002, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4072-8795","authenticated-orcid":false,"given":"Juan Carlos","family":"Nieves","sequence":"additional","affiliation":[{"name":"Department of Computing Science, Ume\u00e5 University, 901 87 Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ghosh, S.K., and Ghosh, S.C.
