针对单一无人机中继网络中源节点数据业务需求量分布不均引起的局部数据拥塞问题,提出一种由固定翼无人机和旋翼无人机组成的异型无人机中继网络模型。在此基础上,探讨异型无人机网络和用户间的接入点选择算法,提出适用于异型无人机中继网络的基于模糊逻辑理论的接入点选择算法。在异型无人机中继网络环境下,仿真分析比较所提算法和传统算法在网络吞吐量和中断频率方面的性能差异,结果表明所提算法能使异型无人机中继网络具有更高的吞吐量和更低的中断频率。

In order to solve the problem of local data congestion caused by the uneven distribution of source node data service demand in a single UAV relay network, a heterogeneous UAV relay network which is composed of rotorcrafts and fixed-wing aircrafts is proposed in this paper. On this basis, the algorithm of network access point selection for the heterogenous UAV relay network is discussed, and an access point selection algorithm based on fuzzy logic theory is proposed.Then the simulation about this heterogeneous UAV relay network is carried out and the differences at the aspects of throughput and interruptions between the proposed algorithm and traditional algorithm are analyzed. The results show that the proposed algorithm brings the heterogeneous UAV relay network higher throughput and less interruptions.
