- Modeling of Two-Flow Interactions Under SINR Model in Multi-Hop Wireless Networks
- Carrier Sense Multiple Access CSMA protocols in Multi-hop Wireless Networks MHWN are known to suffer from different forms of the hidden and exposed terminal problems, leading to inefficiency and unfairness. Recent studies have formally characterized the fundamental interactions in the IEEE 802.11 protocol by classifying and quantifying the possible interactions...

- TCP Over WiMAX: A Measurement Study
- This paper present active measurement results from a commercial IEEE 802.16/WiMAX-based network, with primary focus on TCP performance. This paper compare four TCP variants, namely New Reno, Cubic, Vegas and Veno, using throughput, Round-Trip Time RTT, and retransmission rate metrics. While all TCP variants achieve similar throughput, they do so...

- Endlessly extending copyright
- The European Commissioner for Internal Market and Services, Charlie McCreevy, recently declared that copyright for performers be extended from 50 to 95 years. This was proposed, according McCreevy, to remedy a fundamental unfairness, wherein the composer the author of a song has rights that extend 70 years after his death, whereas...

- TCP Testing - Preventing Global Internet Warming
- Do the new TCP congestion control algorithms and other changes have unfairness that could lead to congestion collapse? Testing multiple flows using applications rsync and ftp shows some unfairness exists when the bottleneck queue is large; but the new algorithms are no more unfair than standard TCP. The Transmission Control...

- 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...

- A Cross-Layer Approach for Per-Station Fairness in TCP Over WLANs
- This paper investigates the issue of per-station fairness in TCP over IEEE 802.11-compliant Wireless Local Area Networks WLANs, especially in Wi-Fi hot spot. It is asserted that the hot spot suffers from the unfairness among stations in exploiting the wireless medium. The source of this unfairness is analyzed from two...

- A Study of TCP Fairness in High-Speed Networks
- Under the TCP congestion control regime, heterogeneous flows, i.e., flows with different Round-Trip Times RTTs, that share the same bottleneck link will not attain equal portions of the available bandwidth. In fact, according to the TCP friendly formula, the throughput ratio of two flows is inversely proportional to the ratio...

- Wireless Local Area Networks WLANs based on the IEEE 802.11 technology have become increasingly popular and ubiquitous. The 802.11 standard allows each station in a WLAN equal opportunity to access the wireless channel, which can result in unfair sharing of network bandwidth between upstream and downstream TCP flows at an...
