Abstract
A method for reducing unnecessary retransmissions due to transmission delays in a wireless network environment, comprising: measuring a packet inter-arrival time with respect to a received data packet; transmitting an acknowledgement packet corresponding to the data packet received at the packet inter-arrival time in excess of a first threshold time when the measured packet inter-arrival time exceeds the first threshold time; and suspending transmission of an acknowledgement packet corresponding to a new data packet when a data packet received after having transmitted the acknowledgement packet is the new data packet that has not previously been received.
