# Context-Aware Caching Distribution and UAV Deployment: A Game-Theoretic Approach
## 3 UAV-Assisted Caching Game
### Log-Linear Caching Algorithm
The proposed model combined with game theory was proved to be effective, which was shown in the simulation results. Meanwhile, the simulation results indicated that the performance of UAV-assisted networks was related with the number of system files, cache space of UAVs, and the number of UAVs in service. Inspired by the related simulation results, increasing the number of UAVs in service is not the only way to improve the quality of service. In real life, the performance of UAV-assisted networks can be improved by reasonable arrangement of UAVs' caching contents and service locations.
