Effect of Rotation of a High Altitude Platform on Handover

Abstract:

High altitude platform station (HAPs) system is a novel and promising communication infrastructure, providing various wireless mobile services in Third Generation (3G) even Forth Generation (4G) communication. Because of the wind, variation of temperature and some other complexity conditions in the layer of stratosphere, HAPs might inevitably encounter relative movement to the ground. In this paper, two rotation models rotate around z-axis and x or y-axis respectively are constructed to illustrate the effects on handover. Computer simulation shows that the average possibility of handover is definitely determined by the rotation direction, cell’s position and rotation angle; the critical rotation angle of handover is also calculated when the cell’s position and the altitude of platform are fixed.
