Selection of handoff method for serving air traffıc control communication in Leo satellite constellation

Abstract

Due to the satellite motion with respect to the earth' s surface and the aircraft's mobility, it is required to handover frequently in the process of communicating , In This paper ,assuming that the aircraft's location and speed can be determined , we proposes a suitable study for managing handover in satellite constellations for serving air traffic communication . The main objective of This study is selecting the best scheme which reduce significantly contact failure Probability ,this techniques are: non priority, priority, and queuing handoff schemes ,in this paper we are interested only in schemes that prioritize handover request in particular handoff queuing schemes. Channel allocation strategy (FCA) is employed, and the simulation results obtained concern: call blocking probability, handover failure probability, and average waiting time in the queue. Also simulation results are compared to choose the best one which reduces the contacts failureownership ratios. That supports more firm specific information is incorporated into stock prices as the ratio of foreign ownership increases.
