TCP Contention Control: A Cross Layer Approach to Improve TCP Performance in Multihop Ad Hoc Networks
White Paper This paper proposes a novel cross layer solution called "TCP Contention Control" that dynamically adjusts the amount of outstanding data in the network based on the level of contention experienced by packets as well as the throughput achieved by... [19 Dec 2007]
Improving TCP Performance Over Mobile Ad Hoc Networks by Exploiting Cross-Layer Information Awareness
White Paper TCP performance degrades significantly in mobile ad hoc networks because most of packet losses occur as a result of route failures. Prior work proposed to provide link failure feedback to TCP so that TCP can avoid responding to route failures as if... [30 Oct 2007]
A Cross Layer Analysis of TCP Instability in Multihop Ad Hoc Networks
White Paper As this paper shows, TCP instability is truly a cross layer problem which needs to be addressed by considering the interaction of multiple layers with each other. It is well-known that due to the nature of some ad hoc network applications (e.g... [26 Dec 2007]
TCP-Friendly Medium Access Control for Ad-Hoc Wireless Networks: Alleviating Self-Contention
White Paper This paper focuses on self-contention - contention between packets of the same transport layer connection along the path from source to destination. The paper proposes and studies two MAC-layer approaches to alleviate self-contention. [23 Aug 2007]
Data Link Layer Control Methods for Performance Improvement of TCP Over an Ad Hoc Network
White Paper In order to increase TCP performance in an ad hoc network, support from the lower layers of the transport layer is required. Although retransmission by the data link layer is generally required for errors on a wireless channel in ad hoc networks... [20 Dec 2007]
Hidden Terminal Analysis on TCP Stability Over Multihops Ad Hoc Networks
White Paper This paper points out and verifies that the TCP instability comes from the hidden terminal problem due to the MAC layer collisions through the analysis of the tracing data in extensive simulations. The hidden terminal will produce large volumes of... [08 Jan 2008]

TCP Over Multihop 802.11 Networks: Issues and Performance Enhancement
White Paper Analyzing TCP operation over 802.11 multihop ad hoc networks involves a cross-layer study. This paper investigates the effect of congestion and MAC contention on the interaction between TCP and on-demand ad hoc routing protocol in the 802.11 ad hoc... [06 Oct 2005]
Improving the Performance of TCP in the Presence of Interacting UDP Flows in Ad Hoc Networks
White Paper This paper studies how fairness affects the performance of TCP over ad hoc networks with IEEE 802.11 at the MAC layer. The problem addressed is that the throughput of TCP flows degrades severely in the presence of heavily loaded UDP flows. [14 Jan 2008]
ATP: A Reliable Transport Protocol for Ad-Hoc Networks
White Paper Toward this end, it presents a new reliable transport layer protocol for ad-hoc networks called ATP (ad-hoc transport protocol). Existing works have approached the problem of reliable transport in ad-hoc networks by proposing mechanisms to improve... [05 Dec 2007]

On Channel Selection Strategies for Multi-Channel MAC Protocols in Wireless Ad Hoc Networks
White Paper This channel selection strategy reduces link-layer data frame losses and provides higher TCP throughput compared to the other channel selection approaches. Multi-channel Medium Access Control (MAC) protocols have recently been proposed to improve... [26 Dec 2007]
Performance of TCP/UDP Under Ad Hoc IEEE802.11
White Paper TCP is the De facto standard for connection oriented transport layer protocol, while UDP is the De facto standard for transport layer protocol, which is used with real time traffic for audio and video. [06 Nov 2007]
