Inside wireless LAN, access point always sends long term TCP packets first followed by short term TCP packets. Due to this, there is unfairness for short term packets. In this paper, we come up with a novel approach to address this issue using a priority based scheme and URG (urgent) flag in TCP header. At the same time round robin mechanism is used for non-priority based short term TCP packets which not only improves throughput of the network and provides fairness but also avoids TCP from implementing the slow-start and congestion avoidance strategy assuming the loss of packets inside wireless networks.
