基于干扰对齐的群飞无人机自组网能效优化与调度方法研究

The main characteristics of unmanned aerial vehicles (UAVs) network include limited energy, high mobility, fluid topology changes, 3D and long transmission delay of links between UAVs and satellite. To improve its transmission and energy efficiency, on the basis of the good research on the operation regularity of UAVs network，we plan to study the theory and technology of the schemes based on the newly invented idea of interference alignment to ensure efficient, reliable and energy saving information transmission scheduling for UAVs swarm network. And the schemes will be optimized through cross-layer design and other optimization technologies. First of all, Foundational problems of the time domain interference alignment based information transmission scheduling method for UAVs network considering air and space integration and optimization method will be investigated. Second, a novel Energy efficiency optimization method for UAVs network based on space domain interference alignment will be proposed creatively. Then, Hybrid and cross-layer energy efficiency optimization scheme for UAVs network based on interference alignment will be constructed. Last, the interference alignment-based simultaneous wireless information and power transfer algorithm for UAVs network will be proposed to break through energy limitation. Our results will collaboratively constitute the system of efficient, cross-layer and energy saving network protocols adapting to characteristics of UAVs network which is integrated in air, space and ground network, and contribute for its practicability.
