Multicriteria Data Processing Management in the Geographically Distributed Computing Systems with QoS Time Requirements
Anna Klimenko · 2023
This paper is devoted to the problem of data processing management in fog- and edge-computing environments. The main issue of task planning is that the environments of the fog and edge network tiers are dynamic and heterogeneous in terms of optimization criteria. Previously published papers do not consider the heterogeneity of the criteria in the tasks of data processing, although the heterogeneity of the network generates a wide range of criteria and constraints for the workload distribution. The main contribution of this paper is as follows: the general model of a multicriteria workload distribution problem, which differs from previously proposed ones by the heterogeneous criteria usage, and by the integration of the reconfiguration process into the problem description, taking into account the main QoS time constraint. The basic method of the problem solution is proposed, too, with paying attention to the data transit extra-costs. Some selected simulation examples are described as well, which present the possibility to achieve the solution of the problem formulated.
