Enhanced Scheme for Improving of TCP Performance on Handover in Mobile IPv6 Networks

In the TCP over Mobile IPv6 (MIPv6) Networks, TCP responds to losses such as high bit errors and handovers by invoking congestion control and avoidance algorithms. In this paper we propose new handover notification algorithm scheme that is to send an explicit handover notification message to the source host from mobile host when occurring to handover. Upon receipt of explicit handover notification, the source host enters persist mode. This way, data transmissions at the source host during handover are frozen. In numerical result, proposed algorithm scheme provides a little performance improvement compared with general TCP method, and expects to greater performance improvements while having frequent handover in MIPv6 Networks.
