CoAP and its extensions (e.g., CoAP observe and group communication) provide the potential for developing novel applications in the Internet-of-Things (IoT). However, a full-fledged CoAP-based application may require significant computing capability, power, and storage capacity in IoT devices. To address these challenges, we present the design, implementation, and experimentation with the CoAP handler which provides transparent CoAP services through the ICN core network. In addition, we demonstrate how the CoAP traffic over an ICN network can unleash the full potential of the CoAP, shifting both overhead and complexity from the (constrained) endpoints to the ICN network. The experiments prove that the CoAP Handler helps to decrease the required computation complexity, communication overhead, and state management of the CoAP server.<\/jats:p>","DOI":"10.3390\/s19061339","type":"journal-article","created":{"date-parts":[[2019,3,18]],"date-time":"2019-03-18T12:18:53Z","timestamp":1552911533000},"page":"1339","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Transparent CoAP Services to IoT Endpoints through ICN Operator Networks"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1887-2005","authenticated-orcid":false,"given":"Hasan Mahmood Aminul","family":"Islam","sequence":"first","affiliation":[{"name":"Department of Computer Science, Aalto University, Espoo 02150, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dmitrij","family":"Lagutin","sequence":"additional","affiliation":[{"name":"Department of Communications and Networking, Aalto University, Espoo 02150, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antti","family":"Yl\u00e4-J\u00e4\u00e4ski","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Aalto University, Espoo 02150, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9100-1081","authenticated-orcid":false,"given":"Nikos","family":"Fotiou","sequence":"additional","affiliation":[{"name":"Department of Informatics, Athens University of Economics and Business, Athens 11362, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9829-9287","authenticated-orcid":false,"given":"Andrei","family":"Gurtov","sequence":"additional","affiliation":[{"name":"Department of Computer and Information Science, Link\u00f6ping University, SE-581 83 Link\u00f6ping, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,17]]},"reference":[{"key":"ref_1","unstructured":"Jung, H.
