This large number of objects will generate a huge amount of data that is currently being processed and stored in the cloud. Fog Computing presents a promising solution to the problems of high latency and huge network traffic encountered in the cloud. As Fog\u2019s infrastructures are dense, heterogeneous and geo-distributed, managing the data in order to satisfy users demand in such context is very complicated. In this work, we propose a data management strategy called \u2018RMS-HaFC\u2019 in which we consider the characteristics of Fog Computing environment. To do so, we proposed a hierarchical multi-layer model, on which we designed a migration and replication strategy based on data popularity. These strategies duplicate files dynamically and store them in different locations to improve the response time of users requests and minimize the system energy consumption without loading network usage. The strategy was evaluated using the iFogSim simulator and the experimental results obtained are very promising.<\/jats:p>","DOI":"10.3233\/mgs-200333","type":"journal-article","created":{"date-parts":[[2020,11,6]],"date-time":"2020-11-06T11:51:53Z","timestamp":1604663513000},"page":"291-307","source":"Crossref","is-referenced-by-count":4,"title":["A replication and migration strategy on the hierarchical architecture in the fog computing environment"],"prefix":"10.1177","volume":"16","author":[{"given":"Ahmed","family":"Berkennou","sequence":"first","affiliation":[{"name":"Department of Computer Science, Faculty of Exact and Applied Sciences, University of Oran 1, Ahmed Ben Bella BP. 1524, EL M\u2019Naouer, Oran, 31000, Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ghalem","family":"Belalem","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Faculty of Exact and Applied Sciences, University of Oran 1, Ahmed Ben Bella BP. 1524, EL M\u2019Naouer, Oran, 31000, Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Said","family":"Limam","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Faculty of Exact and Applied Sciences, University of Saida, Dr Taher Moulay Route de Mascara, Saida, 20000, Algeria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"issue":"15","key":"10.3233\/MGS-200333_ref1","doi-asserted-by":"crossref","first-page":"2787","DOI":"10.1016\/j.comnet.2010.05.010","article-title":"The internet of things: A survey","volume":"54","author":"Atzori","year":"2010","journal-title":"Computer Networks"},{"issue":"4","key":"10.3233\/MGS-200333_ref2","doi-asserted-by":"crossref","first-page":"2347","DOI":"10.1109\/COMST.2015.2444095","article-title":"Internet of things: A survey on enabling technologies, protocols and applications","volume":"17","author":"Al-Fuqaha","year":"2015","journal-title":"IEEE Communications Surveys & Tutorials"},{"issue":"3","key":"10.3233\/MGS-200333_ref3","first-page":"37","article-title":"Cloud of things: A state-of-the-art review on integration of internet of things with cloud computing","volume":"2016","author":"Patel","year":"2017","journal-title":"IJCA Proceedings on National Conference on Contemporary Computing NCCC"},{"key":"10.3233\/MGS-200333_ref4","unstructured":"B.
