In 5G era, the base stations are capable of providing multiple services in various scenarios (e.g. vehicle network, Internet of Things), which provides fine opportunity to enhance spectrum efficiency. Base stations can flexibly utilize the idle frequency band for spatiotemporal low-demand services and guarantee services with high priority (e.g. urgent broadcasting), which construct a distributed architecture for spectrum allocation. In this paper, we provide a dynamic spectrum allocation scheme in base station, which can flexibly rearrange spectrum considering service priority, energy consumption and renting cost. We use Lyapunov optimization method to solve the problem. Moreover, we propose online Lyapunov optimization algorithm (OLOA) to figure out the optimal solution of penalty-and-drift function and show mathematical proofs on the performance of the algorithm. The simulation results show that the superiority and stability of our algorithm, which corroborates theoretical analysis. |
