Coupled with low-latency 5G radio access, this enables the creation of high added-value services for mobile users, such as in-vehicle infotainment or remote driving. The performance of these services as well as their scalability will however depend on how MEC will be deployed in 5G systems. This paper evaluates different MEC deployment options, coherent with the respective 5G migration phases, using an accurate and comprehensive end-to-end (E2E) system simulation model (exploiting Simu5G for radio access and Intel CoFluent for core network and MEC), taking into account user-related metrics, such as response time or MEC latency. Our results show that 4G radio access is going to be a bottleneck, preventing MEC services from scaling up. On the other hand, the introduction of 5G will allow a considerable higher penetration of MEC services.<\/jats:p>","DOI":"10.3390\/jsan9040057","type":"journal-article","created":{"date-parts":[[2020,12,13]],"date-time":"2020-12-13T20:56:57Z","timestamp":1607893017000},"page":"57","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["End-to-End Performance Evaluation of MEC Deployments in 5G Scenarios"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0629-1078","authenticated-orcid":false,"given":"Antonio","family":"Virdis","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, University of Pisa, 56021 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9796-6378","authenticated-orcid":false,"given":"Giovanni","family":"Nardini","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, University of Pisa, 56021 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5310-6763","authenticated-orcid":false,"given":"Giovanni","family":"Stea","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, University of Pisa, 56021 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8723-7726","authenticated-orcid":false,"given":"Dario","family":"Sabella","sequence":"additional","affiliation":[{"name":"Intel Deutschland GmbH, Am Campeon 10-12, 85579 Neubiberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,11]]},"reference":[{"key":"ref_1","unstructured":"Intel White Paper (2020, November 10).
