INSIGNIA: An IP-Based Quality of Service Framework for Mobile ad Hoc Networks

White Paper Architecturally INSIGNIA is designed to support fast reservation, restoration,and end-to-end adaptation based on the inherent flexibility and robustness and scalability found in IP networks. Our results show the benefit... [03 Jul 2008]

TCP-Aware Resource Allocation in CDMA Networks

White Paper The work discusses in this paper explores cross-layer optimization of the rate adaptation feature of cellular networks to optimize throughput of a single long-lived TCP session. However, the set of data rates as well as... [27 Dec 2007]

Joint PHY/MAC Based Link Adaptation for Wireless LANs With Multipath Fading

White Paper Thus, a cross-layer based design approach along with link adaptation is required to improve the network performance under different channel conditions. Wireless local area networks offer... [03 Sep 2007]

An Adaptive Two-Dimensional Channel Estimator for Wireless OFDM With Application to Mobile DVB-T

White Paper The paper proposes an efficient algorithm for adaptation to time varying channels of the second filter. Depending on the channel conditions, the signal-to-noise ratio gain can be up to... [11 Apr 2007]

PER-Prediction for Link Adaptation in OFDM Systems

White Paper This possibility, termed Link Adaptation (LA), is a key element for meeting Quality of Service (QoS) requirements and optimizing system performance and bandwidth efficiency. The physical layers (PHY) of modern wireless... [02 Nov 2004]

Performance and Configuration of Link Adaptation Algorithms With Mobile Speed

White Paper Link Adaptation is an adaptive radio link technique that selects a transport mode, from a set of predefined modes of varying robustness, depending on the channel quality conditions and... [25 Jun 2004]

The Havana Framework for Supporting Application and Channel Dependent QOS in Wireless Networks

White Paper Our framework is based on three different mechanisms that operate over distinct adaptation time scales. Over even longer time scales an adaptor regulates flows taking into account the ability of wireless applications to... [25 Feb 2004]
