Advanced Cross-Layering Algorithm for Mobility Management Architecture in Heterogeneous Wireless Networks

The advantage of proxy mobility management protocol over IPv6 is that it efficiently manages the latency time caused by a handover as the router on the access network takes the role of the mobility management of a mobile device instead. However, the frequent occurrences of handovers on the nested access network causes the increase of load on the MAG, which then brings about the loss of packets and delay of the handover process. Although fast proxy mobility management protocol has been suggested to resolve this problem, various implementations of the beacon or router advertisement on the wireless network and continuous research are required to provide stable multimedia traffic services. The proposed advanced cross-layering algorithm (ACL) builds a bi-directional tunnel between MAGs, based on the mobility prediction between the access routers on the nested network, using the reverse binding mechanism to optimize the route of the packets and therefore increase the efficiency of packet forwarding.
