Abstract
With the wide application of unmanned aerial vehicle (UAV), especially in the military field, the security of inter-aircraft communication has become a critical issue, but the wireless ultraviolet communication can be used as a new communication method to guarantee the communication of UAVs within circular cluster. This paper mainly studies the analytical model for connectivity when UAVs obey random way point (RWP) model based on ultraviolet communication within circular cluster. Connectivity is one of the most important characteristics in network, especially in high-dynamic UAV network. Simulations are made when UAVs in cluster obey uniform distribution and RWP model with modulations of OOK and PPM. The simulation results under different distributions of UAVs indicate that transmitted power required with OOK to achieve same probability of k-connectivity is about 2 times than that required with PPM, whereas the data rate required with OOK is about 0.5 times than PPM. In addition, we compare the approximation method based on the analytical model proposed in this paper with the existing approximation method in three cases, where the number of UAV is 20, 100 and 500, respectively. The simulation results show that the approximation method proposed in this paper converges to 1 much faster.
