Abstract :
In the future mobile Internet, one of the most challenging aspects is to discover the available neighbor access networks and it´s characteristics as the user moves. Using the IEEE 802.21 Media Independent Handover (MIH) standard, this letter 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 proposed model can significantly improve the mobility user experience.
