A TCP Fairness Improvement Scheme for Wired and Wireless Heterogeneous Networks
Sung‐Joon Cho, Seong-Chul Kim · The Journal of Advanced Navigation Technology · 2006
Multiple wireless devices in wired and wireless heterogeneous networks communicate with counterparts via a single Access Point (AP). In this case, the AP becomes a bottleneck of the network, therefore buffer overflows occur frequently and result in TCP performance degradation. In this paper, the new algorithm that prevents buffer overflows at AP and enhances TCP fairness is proposed. Depending on the buffer usage of AP, the new algorithm adaptively controls each TCP senders' transmission rate, prevents buffer overflows and thus guarantees improved TCP fairness. It is proved that the algorithm makes better of TCP throughput and fairness by preventing buffer overflows.
