Introduction of Handover Manager for Better Handover Latency and Handover Throughput during Leo Satellite Handover

Abstract

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 (SeaHO-LEO) ,PatHO-LEO .In our proposed 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.

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

“…iv) FA decapsulate those packets and sent it to MN. Another method is Seamless handover management scheme (SeaHO-LEO) [14], [15] In our previous work [16] we have introduced a new Handover Manager (HM) which will reduce the binding updates and handover latency as it shows that there is no need to send and receive handover preparation request prior to handover. so, the process of the handover of the SeaHO-LEO is just as follows:…”
