Cost Analysis of Handover Manager Based Handover Method in LEO Satellite Networks

LEO satellite has an important role in global communication system. They have advantages like low power requirement and lower end-to-end delay, efficient frequency spectrum utilization between satellites and spotbeams over MEO and GEO satellites. So in future they can be used as a replacement of modern terrestrial wireless networks. There are a lot of handover techniques for LEO satellites like seamless handover (SeaHOLEO), PatHO-LEO. In our previous work, we have suggested a new handover technique for SeaHO-LEO by introducing a Handover Manager (HM) during the handover process and by simulation we have also shown that it a better approach by comparing it with other existing handover techniques as it reduces the handover latency, propagation delay, call blocking probability more than any other technique. In this paper we have evaluated the exact cost of our previous work i.e. Handover Manager based handover Method (HMBHO). Simulation results show that the cost of Handover Manager based handover management method is better than other handover methods.
