Optimized service deployment on both cloud and fog environments is challenging due to their heterogeneity. Prior works mainly focus on mapping service functions and dependencies directly to physical network. In this paper, we propose a multi-layer mapping mechanism that efficiently deploys multiple IoT services to the appropriate virtual networks in physical infrastructure. We design greedy-based algorithms for solving this NP-hard problem with two phases executed sequentially. Experimental results show our proposed solution can reduce upto 80% of the total service cost compared to the state-of-the-art solutions.Van Do Dangdodv@vnu.edu.vnXuan Tung Hoangtunghx@vnu.edu.vnNguyen Kim-Khoakim-khoa.nguyen@etsmtl.ca2020-12-09T14:49:33Z2020-12-11T01:44:19Zhttp://eprints.uet.vnu.edu.vn/eprints/id/eprint/4211This item is in the repository with the URL: http://eprints.uet.vnu.edu.vn/eprints/id/eprint/42112020-12-09T14:49:33ZOptimization of IoT Service Deployment In Multi-Layered Cloud-Fog EnvironmentVan Do Dangdodv@vnu.edu.vnXuan Tung Hoangtunghx@vnu.edu.vnMai TranKim Khoa NguyenKim-Khoa.Nguyen@etsmtl.ca
