RSS ad ieee 802.11Wireless Mesh Networks: A Survey
White Paper The integration of WMNs with other networks such as the Internet, cellular, IEEE 802.11, IEEE 802.15, IEEE 802.16, sensor networks, etc.can be accomplished through the gateway and bridging functions in the mesh routers. [03 Jul 2008]
On Setting TCP's Congestion Window Limit in Mobile Ad Hoc Networks
White Paper It further refines this upper bound based on the IEEE 802.11 MAC layer protocol. Improving TCP performance has long been the focus of many research efforts in Mobile Ad hoc NETworks (MANET). This paper addresses one aspect of this endeavor: how to... [03 Jul 2008]
Benefits of Packet Aggregation in Ad-Hoc Wireless Network
White Paper Emerging mesh networks build on IEEE 802.11 wireless local area networking technology to deliver Internet access to mobile users or to areas where traditional wired access technologies are unprofitable. [03 Jul 2008]
DBASE : a Distributed Bandwidth Allocation/Sharing/Extension Protocol for Multimedia over IEEE 802.11 Ad Hoc Wireless LAN
White Paper In this white paper we propose a distributed bandwidth allocation/sharing/extension (DBASE) protocol to support multimedia traffics with the characteristics of variable bit rate (VBR) and constant bit rate (CBR)over ad hoc WLAN. [03 Jul 2008]
Estimating the Ad Hoc Horizon for TCP Over IEEE 802.11 Networks
White Paper The paper shows that with IEEE 802.11 this horizon is as narrow as 2 to 3 hops and approximately 15 nodes. This paper explores the hypothesis of an "Ad hoc horizon" for wireless multihop networks. This horizon is defined in terms of number of nodes... [15 Jan 2008]
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. [15 Jan 2008]
Split TCP for Mobile Ad Hoc Networks
White Paper Furthermore, if the MAC protocol de-fined in the IEEE 802.11 standard is used, the problems exacerbate due to the capture effect induced by this protocol, leading to a larger degree of unfairness and a further degradation of throughput. [15 Jan 2008]
Alleviating Effects of Mobility on TCP Performance in Ad Hoc Networks Using Signal Strength Based Link Management
White Paper It also proposes a simple mechanism that can help alleviate false link failures that occur due to congestion when the IEEE 802.11 MAC protocol is used. Mobility in ad hoc networks causes link failures, which in turn result in packet losses. [15 Jan 2008]
On Channel Selection Strategies for Multi-Channel MAC Protocols in Wireless Ad Hoc Networks
White Paper Multi-channel Medium Access Control (MAC) protocols have recently been proposed to improve the performance of the Transmission Control Protocol (TCP) in IEEE 802.11 wireless ad hoc networks. This paper uses ns-2 network simulations to study the... [27 Dec 2007]
Empirical Upper Bound on TCP Transmission Rate for Guaranteed Capture-Free Communications in Multi-Hop IEEE 802.11 Based Wireless Networks
White Paper This paper considers the well known problem of TCP capture in mobile ad hoc networks, which is an unfair distribution of network bandwidth between TCP flows. The conventional way of analysis of TCP performance in wireless networks is to consider... [27 Dec 2007]
Improving TCP Performance Over Wireless Ad Hoc Networks With Busy Tone Assisted Scheme
White Paper It is well known that Transmission Control Protocol (TCP) performance degrades severely in IEEE 802.11-based wireless ad hoc networks. The paper first identifies two critical issues leading to the TCP performance degradation: unreliable broadcast... [06 Dec 2007]
A Dynamic Adaptive Acknowledgment Strategy for TCP Over Multihop Wireless Networks
White Paper Multihop wireless networks based on the IEEE 802.11 MAC protocol are promising for ad hoc networks in small scale today. The 802.11 protocol minimizes the well-known hidden node problem but does not eliminate it completely. [06 Dec 2007]
Performance of Reliable Transport Protocol Over IEEE 802.11 Wireless LAN: Analysis and Enhancement
White Paper IEEE 802.11 Medium Access Control (MAC) is proposed to support asynchronous and time bounded delivery of radio data packets in infrastructure and ad hoc networks. The basis of the IEEE 802.11 WLAN MAC protocol is Distributed Coordination Function... [06 Dec 2007]
Extended Abstract: Understanding the Effect of Access Point Density on Wireless LAN Performance
White Paper This paper presents a systematic experimental study of the effect of inter-cell interference on IEEE 802.11 performance. With increasing penetration of WiFi into residential areas and usage in ad hoc conference settings, chaotic un-planned... [06 Dec 2007]
A Short Look on Power Saving Mechanisms in the Wireless LAN Standard Draft IEEE 802.11
White Paper This paper describes simulations of the power saving mechanism of the upcoming standard for wireless Local Area Networks IEEE 802.11. Simulations were made for a ad-hoc-network with 8 stations. They were performed in order to see how typical... [06 Dec 2007]
