Abstract

Reduced throughput of TCP over WLAN is mainly due to traditional TCP protocols treat all packet loss as a sign of congestion, their inability to recognize non-congestion related packet loss has significant effects on the communication efficiency in the wireless networks,?But highly variable round-trip times (RTT) in wireless networks can induce spurious timeouts, thus unnecessarily degrading throughput for the (TCP) greatly[3]. TCP Veno improving traditional TCP achieves a significant success on solving the previous factor, this paper refines Veno mainly with optimization of RTO estimation. The simulated results show that our schemes can further improve TCP throughput in WLAN.
