Proxy Based Mobility Management Scheme Using Prediction Algorithm

Abstract

Nowadays, mobile users are rapidly increased and many mobile environments are proposed by the improvement of wireless devices and network. There are many mobility management protocols are proposed to provide seamless mobile network environment. In this paper, we focused on transportation environment that is one of bus, train, airplane or ship that takes passengers using mobile devices. Transportation environment has a major problem that Mobile Node (MN) moves fast through multiple cells. Each MN in transportation keeps updating its current point of attachment to its Home Agent (HA) and corresponding node that causes triangle routing problem between HA of MN and HA of Mobile Router (MR). To remove triangle routing problem and minimize cost, we proposed mobility management scheme adapting proxy scheme then we propose prediction algorithm. Based on two features, we design proxy based architecture and extend router advertisement message to alert join in proxy domain. Then, we are classified the mobility into intra proxy mobility and global mobility. And we proposed proxy based mobility management scheme using prediction algorithm. We added heuristic that takes into account real world transportation’s movement. By numerical analysis, we shows proposed scheme reduces signaling overheads and increase packet transfer rate than NEMO and proxy MIP.
