Abstract | In this paper, we make the first attempt to investigate the use of erasure codes in cost-effective data storage at the edge. The focus is to find the optimal strategy for placing coded data blocks on the edge servers in an ESS, aiming to minimize the storage cost while serving all the users in the system. We first model this novel Erasure Coding based Edge Data Placement (EC-EDP) problem as a constrained optimization problem and prove that it is NP-hard. Then, we propose an optimal approach named EC-EDP-O based on integer programming. We also propose an approximation algorithm named EC-EDP-V for finding approximate solutions to large-scale EC-EDP problems efficiently. The results of experiments conducted on a widely-used real-world dataset demonstrate that EC-EDP-O and EC-EDP-V can save an average of 68.58% (and up to 81.16% in large-scale scenarios) storage cost compared with replica-based storage approaches. |
