- End-to-end Fairness for TCP Traffic in 802.11e Wireless Mesh Networks Without Coordination
- This paper considers end-to-end per-station1 and per-flow fair bandwidth allocations for TCP traffic in 802.11 based multi-radio multi-hop networks. First it shows that TCP ACK packets have to be prioritised using IEEE 802.11e since otherwise congestion losses of ACK packets cause unpredictable performance. Then it proves that prioritising ACK packets...
