| Abstract: | In order to achieve the mobility of computers during communication,it is necessary to distinguish between losses due to congestion and non-congestion reasons.This paper analyzes the reasons that result in packet losses,succes-sive timeouts,and slow recovery during and after handoff of mobile computer.Aim at the problem existing in fast re-transmission,propose s a strategy that based on the value of window advertisement of ACK.The principle,design and per-formance of the strategy are described in detail. |
