Abstract: In order to deal with the efficient communication challenge with limited computing resources in communication-computing-converged networks, a novel interactive resource scheduling scheme based on transmission and computing collaboration is proposed to overcome the computing-constraint in base station. Firstly, the arrival-departure curve is used to characterize the packet waiting delay and elaborate the coupling relationship between communication resources and computing resources in traditional queue model. Then, a closed-loop two-step tandem queuing model is proposed, in which a feedback link and a module for interaction are introduced to reflect the linkage mechanism between computing resources and communication resources. Based on this model, taking advantage of transmission-computing collaboration, an interactive resource scheduling algorithm is designed to realize computing-capability-aware wireless resource scheduling. Simulation results demonstrate that, compared with several existing scheduling algorithms, the proposed algorithm could reduce the average packet waiting delay by 13.2% while ensuring user fairness in communication-computing-converged networks.
