## 3 A Collaborative Multi-Satellite Selection Algorithm Based on Maximum SINR
### Proposed Satellite Selection Strategy
difference between collided packets more effectively with lower power consumption. The simulation results show that the proposed SC-ACRDA scheme can effectively improve the throughput performance of the RA protocol. The proposed solution is mainly used for the satellite selection problem in LEO satellite collaboration to avoid a collision, and it is also applicable to wireless communication systems that use unmanned aerial vehicles (UAVs) as relay transmission and adopt the RA protocol.
