Abstract We propose a dynamic mobility management framework for Internet Protocol
version 6 (IPv6) and policy enforcement enabled heterogenous wireless networks. Policies
and policy rules are defined depending on network infrastructure facilities, service agree-
ments and negotiation results. Each traffic is coupled with an identifiable traffic flow while
the heterogenous interface flow bindings are regulated by polices. The network selection, flow
distribution, handovers and mobility procedures are flexible and we propose to improve the
decision making via Multiple Attributes Decision Making (MADM). Techniques considered
in the framework include the IPv6 based Network Mobility (NEMO), multihoming capa-
bility, transparent vertical handovers, horizontal handovers and dynamic policy enforcement
matching process to improve the Quality of Service (QoS), Quality of Experience (QoE) and
ubiquitous connectivity. A experiment testbed and simulation models have been constructed
to verify the mobility framework performance in a heterogeneous WiFi, WiMax and UMTS
hybrid environment.
