Optic flow guides us in the right direction

The way we perceive the visual motion of objects as we move is a phenomenon called 'optic flow.' Now, Brown University researchers have discovered that optic flow helps us to walk. They've used Brown's Virtual Environment Navigation Lab, or VENLab, one of the largest virtual reality labs in the U.S....

Scalability Analysis of Rate Adaptation Techniques in Congested IEEE 802.11 Networks: An ORBIT Testbed Comparative Study

Recent real-world measurements in dense congested radio environments have pointed out the inefficiency of frame error-based bit-rate adaptation mechanisms, which significantly reduce network capacity by misinterpreting frame errors due to collisions. These effects are likely to be amplified with the heavy use of media applications. Fortunately, traditional SNR-based rate adaptation,...

On Enriching Ajax With Semantics: The Web Personalization Use Case

With the dawn of Ajax the capabilities of tracking user behavior multiplied. The same holds for the capabilities of adapting the user interface in a Web browser. To provide meaningful adaptation, the events, context and elements of an Ajaxified Portal must be given meaning. This paper shows the use of...

LDA+ TCP-Friendly Adaptation: A Measurement and Comparison Study

This paper presents an end-to-end adaptation scheme, called the enhanced Loss-Delay based Adaptation algorithm (LDA+) for regulating the transmission behavior of multimedia senders in accordance with the network congestion state. LDA+ uses the Real-time Transport Protocol RTP for collecting loss and delay statistics which are then used for adjusting the...

A Software Architecture for Cross-Layer Wireless Network Adaptations

Conventional data networks are based on a layered architecture. The introduction of wireless networks has created a need to violate this layered discipline to create cross-layer designs or adaptations. Ad-hoc implementations of such cross-layer adaptations reduce the level of modularity and abstraction in the network's implementation, giving rise to a...

Quality-of-Service Driven Power and Rate Adaptation for Multichannel Communications Over Wireless Links

This paper proposes a Quality-of-Service QoS driven power and rate adaptation scheme for multichannel communications systems over wireless links. In particular, the paper uses multichannel communications to model the conceptual architectures for either diversity or multiplexing systems, which play a fundamental role in physical-layer evolutions of mobile wireless networks. By...

Predictive Adaptation for Service Level Agreements on the Grid

Users of Grid systems often need to attach Quality of Service QoS information such as time or performance constraints to guarantee timely execution of their application. Grid resources have varying quality and reliability and can easily be swamped by competing applications. If this coincides with the user's execution their results...

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

Wireless local area networks offer a range of transmitted data rates that are to be selected according to estimated channel conditions. However, due to packet overheads and contention times introduced by the CSMA/CA multiple access protocol, effective throughput is much less than the nominal data rates. Most multimedia applications use...

Distributed Cooperative Rate Adaptation for Energy Efficiency in IEEE 802.11-Based Multi-Hop Networks

This paper studies the problem of using the rate adaptation technique to achieve energy efficiency in an IEEE 802.11-based multi-hop network. Specifically, it is formulated as an optimization problem, i.e., minimizing the total transmission power over transmission data rates, subject to the traffic requirements of all the nodes in a...

Peer Group-Based Dependency Management in Service-Oriented Peer-to-Peer Architectures

Dependency management in service-Oriented peer-to-Peer architectures aims at handling functional dependencies between a public service hosted by a service providing peer and all consumer peers that rely on that service. The analysis of dependencies on consumer peers is important for supporting the adaptation of a public service. The uncoordinated adaptation...

Fast-Responsive Link Adaptation for IEEE 802.11 WLANs

This paper proposes a truly-adaptive fast-responsive link adaptation scheme for IEEE 802.11 WLANs Wireless LANs. The key idea is to direct the transmitter station's rate-increasing attempts in a controlled manner such that the responsiveness of the link adaptation scheme can be guaranteed with minimum number of rate-increasing attempts. Since the...

Delay Aware Adaptive Scheduling in Wireless LAN

In this paper, an adaptive opportunistic scheduling scheme is proposed for wireless LANs in the presence of a link adaptation scheme such as Auto-Rate Fall-back ARF. Extensive simulation experiments and scenarios have shown that this scheme outperforms other alternatives in terms of throughput as well as adaptation to different channel...

Delay-Constrained Rate Adaptation for Robust Video Transmission Over Home Networks

This paper considers rate adaptation for robust transmission of high-quality video over home networks, in particular IEEE 802.11 wireless LANs. The approach includes on-line estimation of the time-varying bandwidth available at the application-/transport-layer. The paper proposes a delay-constrained rate adaptation algorithm to select an optimal bit rate, subsequently enforced by...
