Abstract

Transport protocol in mobile devices of HCI (humancomputer interaction) operates both in wired and wireless heterogeneous network. It has been developed from reactive congestion control schemes to proactive congestion control schemes suitable for both wired and wireless networks environment to overcome the poor wireless environment and restricted mobility. Nevertheless, recently proposed TCP's proactive congestion control schemes could not reflect network environment status in detail, there is also a limit to support new mobile services of HCI users. In this paper, we described issues and problems of rate adjustment metrics used for reducing packet loss and congestion loss in TCP-Jersey's available bandwidth estimators. Also, we presented the guideline of selecting more adequate metrics to improve wireless TCP performance of mobile HCI.
