Adaptive Selective Wireless-TCP by Type of Error

Abstract

Wireless network has high BERs because of its path losses, fading, noises and interferences. In the MIP environments, errors in wireless network are divided random error and burst error. Particularly, busty errors is increased the RTO greatly and is initialized window size. So as a result, affect the transfer rate significantly. To solve such problem, In this paper, we propose SSF-TCP that loads enhanced MF-SNOOP modules on the MAP to keep continuous TCP connection in the MIP whenever the handover happens. the paper proposes the SSF-TCP (Selective Snoop with Freeze-TCP) that loads Enhanced MF-SNOOP modules on the MAP in HMIP and maintains TCP connectivity during network layer handovers. The proposed protocol is to predict the random and burst error. So, the number of re-transmission packets is adjusted. Thereafter, as soon as MN in MIP finishes the handover, MN immediately receives its packets.
