Dynamic-P: A Multi-Beam Directional Antenna MAC Protocol Based on Time Slot States Adjustment

Flying ad hoc network (FANET) can be widely used in military or people's livelihood applications because of its flexibility and high efficiency. Multi-beam directional antennas (MBDA) have gradually become a new trend in FANET due to their ability to significantly improve throughput and other performance. Aiming at the defects and shortcomings of traditional media access control (MAC) protocol in MBDA, this paper proposes a dynamic time slot allocation algorithm for MBDA. By introducing the node data volume demand prediction, the time slot state generation probability of the node is adjusted periodically to improve the overall performance of the system. We compare it with the traditional time slot allocation protocol through simulation. The results show that the protocol can significantly improve the communication performance of the system when the system is stable.
