In the future mobile Internet, one of the mostchallenging aspects is to discover the available neighbor accessnetworks and it’s characteristics as the user moves. Using theIEEE 802.21 Media Independent Handover (MIH) standard, thisletter proposes a new neighbor network discovery mechanism,considering a hierarchical view of the network information.Through a NS-2 based simulation, it is shown that the proposedmodel can significantly improve the mobility user experience.
