Study on the k-Connectivity of UV Communication Network Under the Node Distribution of RWP Mobility Model in the Arbitrary Polygon Area

This manuscript studies on the k-connectivity (k = 1, 2, 3) of ultraviolet (UV) non-line-of-sight (NLOS) communication network in the arbitrary polygon area where the nodes move according to random waypoint (RWP) mobility. In the paper, based on the relationship between the path loss and the transceiver elevation angles, the change of the communication radii of the UV nodes can be analyzed. Besides, a series of parameters that affect the UV network connectivity probability are numerically researched like node density, transmission power and data rate. The results illustrate that performance of communication mode with small elevation angle is better than that of mode with large elevation angle in the arbitrary polygon area. Furthermore, the 2-connectivity with better robustness in a square area is numerically compared with that in a circular area, and then the network parameters that meet the actual applications are clearly given.
