Research on Task Unloading Algorithm Based on Edge Terminal Server of Power Distribution Station Area

Edge terminal server is one of the important devices for cloud edge collaboration in the future power distribution station area. With the increasing business of the power distribution station area, it needs to process a large amount of user data quickly and efficiently. As a result, it is more and more sensitive to power consumption and task delay, which poses a severe challenge to edge terminal server. To solve this problem, a task unloading algorithm based on edge terminal server is proposed. Firstly, a directed acyclic graph is constructed according to the distribution characteristics of the edge terminal server in the power distribution station area, and the complete parallelism between the edge terminal server and the equipment in the power distribution station area is established. Then, the task offloading is described as a joint optimization problem to minimize the energy consumption and task delay, and a heuristic intelligent algorithm is proposed to ensure the dependencies between subtasks and improve the task efficiency. Finally, the effectiveness of the proposed algorithm is verified through the Matlab/simulink simulation results.
