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).
Highlights
Modern terrestrial networks are designed as per to give the low cost and best quality service
The paper is organized as follows: In the second section we have described the related works on handover management including Mobile IP, SeaHO-LEO, PatHO-LEO and our previously proposed Algorithm Based Billboard Manager Based Handover method (BMBHO)
The no of user who do not have a specific mobility pattern in a week is increasing day by day like salesman, LIC worker who have to go different place at different time in a week. To overcome these existing problems the handover management protocol proposed is named as BMBHO i.e. Billboard Manager Based Handover Technique where billboard manager (BM) only stores satellite location signal strength based on QoS parameters[12][13]
Summary
Modern terrestrial networks are designed as per to give the low cost and best quality service. Among which Low Earth Orbit satellite is the best for communication and as the replacement of future terrestrial wireless networks as it has some advantages like a. An unsuccessful handover can degrade the system performance like call quality as well as it call because the forced call termination To solve these problems different handover technique has been proposed [5] [6]. The main drawbacks of this protocol are: It has High handover latency packet lost rate is very high It has insufficient routing path Conflicts with network security solution. To overcome this drawbacks another protocol have been proposed i.e. Seamless handover management scheme (SEAHO-LEO) [9] [10] [11]
