A New Method for Fast and Low Cost Handover in Leo Satellites

Now-a-days LEO satellites have an important role in global communication system. They have some advantages over GEO & MEO satellites such as power requirement and end-to-end delay is lower and it has more efficient frequency spectrum utilization between satellites and spotbeams. So in future they can be used as a replacement of modern terrestrial wireless networks. But they main problem of LEO satellites is that they have large relative speed than the speed of mobile nodes (MN) & earth. That's why the handover occurrence is more. So the call blocking Probaility (Pb) and force call termination Probability (Pf) is also higher. To overcome this problem several handover techniques is proposed.
