Task-Offloading and Resource Allocation Strategy in Multidomain Cooperation for IIoT

Abstract

This study proposes a task-offloading and resource allocation strategy in multidomain cooperation (TARMC) for the industrial Internet of Things (IIoT) to resolve the problem of the non-uniform distribution of task computation among various cluster domain networks in the IIoT and the solidification of traditional industrial wireless network architecture, which produces low efficiency of static resource allocation and high delay in closed-loop data processing. Based on the closed-loop process of task interaction of intelligent terminals in wireless networks, the proposed strategy constructs a network model of multidomain collaborative task-offloading and resource allocation in IIoT for flexible and dynamic resource allocation among intelligent terminals, edge servers, and cluster networks. Considering the partial offloading mechanism, various tasks were segmented into multiple subtasks marked at bit-level per demand, which enabled local and edge servers to process all subtasks in parallel. Moreover, this study established a utility function for the closed-loop delay and terminal energy consumption of task processing, which transformed the process of multidomain collaborative task-offloading and resource allocation into the problem of task computing revenue. Furthermore, an improved Cuckoo Search algorithm was developed to derive the optimal offloading position and resource allocation decision through an alternating iterative method. The simulation results revealed that TARMC performed better than strategies.

“…Yin et al [3] proposed a novel framework to effectively extract industrial safety knowledge, which summarizes the knowledge concept entities of machine and model description languages by combining the asset management shell. Dai et al [4] presented a taskoffloading and resource-allocating technique in multidomain cooperation (TARMC) for the industrial Internet of Things (IIoT) in response to the non-uniform distribution of task allocation between different cluster domain networks and the stability of conventional industrial wireless network architecture. The results indicate the superior performance of the Gaussian process technique, due to its lower error bandwidth.…”
