is introduced. Using this handoff mechanism, the FA will actively freeze the FH’s TCP sender
whenever it detects a handoff in progress. Following are the detailed operations of TCPMobile.
27.3.1 Connection Establishment and Data Transfer
If the FH initiates the connection, it will send a TCP segment with the SYN bit on and the ACK
bit off to the MH through the HA. When this segment reaches FA, FA will issue an ACK to the
FH on behalf of the MH, and the connection between FA and FH is established. The FA then

If the MH initiates the connection with another host (FH or another MH), it will ...
