The first one uses
the split-connection approach, which introduces a fix middle
agent between the mobile host (MH) and correspondent host
(CH) [4]. The connection between CH and MH is broken
into two parts, the fixed part between the CH and the agent
remains unchanged regardless of the position of the MH, and
the TCP connection between the agent and the MH will be
re-established whenever the MH handovers to a new address.
In this sense only the TCP at the MH is affected, while at the
