Abstract
A method for offloading decision and resource allocation based on integration of communication, sensing and computing is provided. A system cost function is defined by considering energy consumption, time delay, and migration costs. Under the constraints of user sensing failure rate and maximum task completion time delay, a long-term average cost minimization problem is established. Based on Lyapunov optimization theory, a virtual queue is established to evaluate the user sensing performance. By using Lyapunov drift-plus-penalty function, the long-term stochastic optimization problem is transformed into a deterministic optimization problem with a single time slot. The transformed problem is divided into inner and outer layers. The inner layer obtains the optimal task offloading ratio for each user base station selection and channel allocation through theoretical derivation. The outer layer determines the user base station selection and channel allocation based on the results of solving the inner layer problem through matching theory.
