Seamless Internetworking of WLANs and Cellular Networks: architecture and performance issues in a Mobile IPv6 scenario''

We review the problem of network mobility and internetworking between heterogeneous data networks and present an approach to the integration of WLAN and cellular networks based on loose coupling and the use of emerging mobility protocols. The handoff performance of such approach is studied, at network and transport level, in a realistic scenario along with the impact on global performance of transport protocols. Finally, a method for eliminating any packet loss at the network layer during the handoff is presented and evaluated.
