Download The approach of Mobile IP (MIP) handoffs that can be controlled by a Generic Link Layer concept, which is described in this paper, is part of IPonAir project funded by BMB+F (German government). To provide seamless mobility between heterogeneous access networks, the IPonAir system architecture is based on Mobile IP, and its Hierarchical Mobile IP extension. However, the decision of Mobile IP handoffs between heterogeneous subnets will have to be more complex. The handoff decision should be based on application-specified policies and user requirements as well as periodic measurements of the quality of the underlying network connectivity.
