Abstract

We propose and evaluate a vertical handover mechanism for TCP, based on receiver Bandwidth Delay Product (BDP) measurement and congestion control using the receiver's advertised window. It addresses the negative impact of abrupt changes in link capacity and latency on TCP performance during make-before-break vertical handover in heterogeneous networks, enabling TCP to seamlessly adapt to new conditions. It resolves the problem of buffer overflow in a low capacity network on handover from a high capacity network, and the under-utilisation problem on handover in the reverse direction. All modifications are restricted to the mobile device, and the proposed technique is fully interoperable with existing TCP and Mobile IP infrastructure. It maintains end-to-end semantics, supports IP security, and can be easily deployed.
