“…In pre-authentication schemes, the MN authenticates with the new satellite immediately after the scan cycle finishes. [8][9] Re-Association: Re-association is a process for transferring associations from old satellite to new one. Once the MN has been authenticated with the new satellite, re-association can be started.…”

Low Earth Orbit (LEO) satellite made a great impact to the scientists towards the end of the previous decade because of its some interesting features such as low propagation delay, low power requirements and the ability to communicate with handheld terminals. That's why future satellite networks are now conceived as complementary rather than competitive to terrestrial networks. But as the speed of LEO satellite is higher than Mobile Nodes (MN) and earth's speed, the no of handover occurrence is more which degrades the overall communication quality. Also the call blocking probability and forced call termination probability is more. To solve these problems, a number of handover methods have been proposed by different scientists. Here we have proposed a fast method for handover named Location Manager Based Handover method for LEO satellite networks where we have use Location Manager (LM) for reducing the scanning time. LM is used to store all the mobility pattern of all the satellites. To know how this method works, we run a set of simulations for handover latency, handover throughput and call blocking probability for our proposed method with the standard methods. Results show that this algorithm can significantly improve the overall communication performance.

Abstract-Now-a-days LEO satellites have an important role in global communication system. They have some advantages like low power requirement and low end-to-end delay, more efficient frequency spectrum utilization between satellites and spot beams over GEO and MEO. So in future they can be used as a replacement of modern terrestrial wireless networks. But the handover occurrence is more due to the speed of the LEOs. Different protocol has been proposed for a successful handover among which BMBHO is more efficient. But it had a problem during the selection of the mobile node during handover. In our previous work we have proposed an algorithm so that the connection can be established easily with the appropriate satellite. In this paper we will evaluate the mobility management cost of Algorithm based Billboard Manager Based Handover method (BMBHO). A simulation result shows that the cost is lower than the cost of Mobile IP of SeaHO-LEO and PatHO-LEO.Keywords-Component; Handover latency; LEO satellite; Mobile Node (MN); Billboard Manager (BM).

LEO satellites have important advantages over geostationary satellite such as low power requirements, low propagation delay and more efficient spectrum delay. But, the handover management in LEO satellite becomes challenging for supporting global mobile communication. Here we propose a new method of introducing a location manager which will store the previous ip s depending on users choice and comparing the new ip address with the stored one and taking the decision whether to register or not. This method also reduces the binding updates and the packet loss during communication. It is the most useful process when the previous ip addresses are repeated for several times during a short span.
