Loss Recovery Scheme for TCP Using MAC MIB over Wireless Access Networks

In the wireless network, if the TCP cannot identify the wireless error, it overly reduces the transmission rate by unnecessarily cutting the congestion window down. Therefore, to improve TCP goodput by accurately detecting wireless loss, we propose the MAC MIB based loss recovery scheme that can differentiate between congestion loss and wireless loss without intervention of any intermediate node. The simulation results show that the goodput is substantially enhanced compared to existing schemes in the wireless access network environment, where errors tend to occur in burst due to the intrinsic wireless link characteristics.
