Summary :

This paper proposes "Mobility-Aware TCP" to solve the problem that arises with New-Reno TCP if Post Registration Handover is used. In Mobility-Aware TCP, when the MT holds an unreturned ACK after handover, lost segments are retransmitted by Flow Control instead of Congestion Control. Therefore, the sender can retransmit segments without throttling the transmission rate. Moreover, if there is no ACK, the MT chooses retransmission schemes that can get higher throughput. Computer simulations compare Mobility-Aware TCP to New-Reno TCP with Post Registration Handover, and New-Reno TCP without Post Registration Handover. The simulations show that the proposal can maintain high throughput even in the face of high segment loss or long handover latency.
