Evaluation of fog topologies in fog planning for IoT task scheduling
Zhiming He, Limei Peng · ACM Symposium on Applied Computing · 2020
In this paper, we investigate the impact of different fog topologies in fog planning on provisioning diverse IoT tasks under an integrated cloud and fog framework (iCloudFog). Two Integer Linear Programming (ILP) models are proposed for ring and star topologies, respectively. Note that similar issue for fully-connected mesh topology has been addressed in our previous work[2], which will be used as a benchmark in the performance comparison. Numerical analyses and comparisons are conducted in terms of the CAPEX, OPEX and average hops for different topologies.
