We propose a proactive multi-level cache selection scheme to enhance the consumer mobility support in Named Data Networking. This scheme focuses on a handover situation, wherein the consumer disconnects from a network or moves to another access router before receiving the requested content. The proactive multi-level cache selection is designed to prefetch contents into a subset of the neighboring routers, to achieve a trade-off between the latency and cache cost. In particular, this approach is feasible for a two-level router structure and scalable to a multi-level structure. The results obtained from simulation show that compared with equivalent schemes such as the original no-prefetch scheme in the Named Data Networking and the all-prefetch scheme, proactive multi-level cache selection for a two-level router structure can provide a better handover performance to some extent; the user experience is improved and the negative impacts of consumer mobility are alleviated. <\/jats:p>","DOI":"10.1177\/1550147717700897","type":"journal-article","created":{"date-parts":[[2017,4,11]],"date-time":"2017-04-11T07:25:54Z","timestamp":1491895554000},"page":"155014771770089","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["A proactive multi-level cache selection scheme to enhance consumer mobility support in Named Data Networking"],"prefix":"10.1177","volume":"13","author":[{"given":"Lanlan","family":"Rui","sequence":"first","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suijia","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haoqiu","family":"Huang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,4,11]]},"reference":[{"key":"bibr1-1550147717700897","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2012.6384448"},{"key":"bibr2-1550147717700897","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2013.070813.00063"},{"key":"bibr3-1550147717700897","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2012.6231276"},{"key":"bibr4-1550147717700897","doi-asserted-by":"publisher","DOI":"10.1145\/1282427.1282402"},{"journal-title":"Technical Report, PARC, Palo Alto, CA","year":"2010","author":"Zhang L","key":"bibr7-1550147717700897"},{"key":"bibr8-1550147717700897","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2012.6384450"},{"first-page":"13","volume-title":"Proceedings of the ACM ICN workshop","author":"Kim DH","key":"bibr9-1550147717700897"},{"key":"bibr10-1550147717700897","doi-asserted-by":"publisher","DOI":"10.1109\/TSE.2003.1265521"},{"key":"bibr11-1550147717700897","doi-asserted-by":"publisher","DOI":"10.1109\/TCE.2011.5955182"},{"first-page":"595","volume-title":"Proceedings of the IEEE international conference on consumer electronics","author":"Lee J","key":"bibr12-1550147717700897"},{"first-page":"37","volume-title":"Proceedings of the 2013 seventh international conference on innovative mobile and internet services in ubiquitous computing (IMIS)","author":"Rao Y","key":"bibr13-1550147717700897"},{"first-page":"61","volume-title":"Proceedings of the ACM ICN workshop","author":"Vasilakos X","key":"bibr14-1550147717700897"},{"first-page":"361","volume-title":"Proceedings of the IEEE INFOCOM 2004","author":"Mishra A","key":"bibr15-1550147717700897"},{"first-page":"213","volume-title":"Proceedings of the 4th ACM international symposium on mobile ad hoc networking and computing","author":"Pathirana PN","key":"bibr16-1550147717700897"},{"first-page":"863","volume-title":"Proceedings of the 2014 IEEE GLOBECOM workshops (GC workshops)","author":"Malak D","key":"bibr17-1550147717700897"},{"first-page":"2043","volume-title":"Proceedings of the 2008 IEEE international conference on communications","author":"Long X","key":"bibr18-1550147717700897"}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1550147717700897","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1550147717700897","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1550147717700897","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,1,14]],"date-time":"2021-01-14T17:44:45Z","timestamp":1610646285000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1177\/1550147717700897"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,4]]},"references-count":16,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2017,4]]}},"alternative-id":["10.1177\/1550147717700897"],"URL":"https:\/\/doi.org\/10.1177\/1550147717700897","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"type":"print","value":"1550-1477"},{"type":"electronic","value":"1550-1477"}],"subject":[],"published":{"date-parts":[[2017,4]]}}}
