ABSTRACT
Though Low Earth Orbit (LEO) satellites have some distinct characteristics such as low propagation delay, low power requirements and more efficient spectrum allocation due to frequency reuse between satellite and spot beams but the higher relative speed than terrestrial mobile networks but it decreases the quality of service as a result of a huge number of handovers. To overcome this problem a number of handover management schemes have been proposed out of which Mobile IP (MIP) is the standard one. But its mobility management cost is too high. Here we have proposed a low cost Coordinates based paging mobility management method (CBPMM) using translation of Coordinates and Paging for LEO satellite networks, which we can find the destination of the mobile node using GPS and translation of coordinates to decrease paging cost in loose location management. Through mathematical analysis simulation results shows that this method is better than the standard mobility management methods.
