Compound TCP will play a central role in future home WiFi networks supporting Internet of Things IoT applications. Compound TCP was designed to be fair but can manifest throughput unfairness in infrastructure-based IEEE 802.11 networks when devices at different locations experience different wireless channel quality. In this paper, we develop ...

This paper introduces an extensible simulation tool for the study of speed scaling designs for a single server with variable service rates. This simulator facilitates detailed performance analysis of scheduling and speed scaling policies under different background settings. Our component-based design separates the system configuration, like the power consumption model ...

Multimedia streaming services such as YouTube and Netflix consume a staggering amount of Internet bandwidth [1]. Furthermore, traditional mechanisms such as proxy caches, content distribution networks, and redundant traffic elimination are rendered ineffective by copyright concerns, regulatory issues, and the growing prevalence of end-to-end encryption. One possible solution is a ...

In this paper, we introduce the notion of decoupled speed scaling, wherein the speed scaling function is completely decoupled from the scheduling policy used in a simple single-server computer system. As an initial result, we first demonstrate that the Fair Sojourn Protocol (FSP) scheduling policy does not work properly with ...

Cluster-based data gathering is widely used in wireless sensor networks, primarily to overcome scalability issues. While clustering is not the most efficient means of gathering data, many clustering algorithms have attempted to provide energy efficiency as well. In this paper, we first demonstrate that the general problem of optimal clustering ...

This paper introduces a novel analytical model for estimating the cache hit ratio as a function of time. The cache may not reach the steady-state hit ratio when the number of Web objects, object popularity, and/or caching resources themselves are subject to change. Hence, the only way to quantify the ...

Anonymous network communication protocols provide privacy for Internet-based communication. In this paper, we focus on the performance and scalability of anonymity protocols. In particular, we develop performance models for two anonymity protocols from the prior literature (Buses and Taxis), as well as our own newly proposed protocol (Motorcycles). Using a ...

We propose a new way of navigating the Web using interactive information visualizations, and present encouraging results from a large-scale Web study of a visual exploration system. While the Web has become an immense, diverse information space, it has also evolved into a powerful software platform. We believe that the ...

We present Fluid Views, a web-based search environment designed to bridge overview and detail by integrating dynamic queries, semantic zooming, and dual layers. The most common form of search results is long ranked and paginated lists, which are seldom examined beyond the top ten items. To support more exploratory forms ...

Protocol-independent redundant traffic elimination (RTE) is a method to detect and remove redundant chunks of data from network-layer packets by using caching at both ends of a network link or path. In this paper, we propose a set of techniques to improve the effectiveness of packet-level RTE. In particular, we ...

ADSL and cable connections are the prevalent technologies available from Internet Service Providers (ISPs) for residential Internet access. Asymmetric access technologies such as these offer high download capacity, but moderate upload capacity. When the Transmission Control Protocol (TCP) is used on such access networks, performance degradation can occur. In particular, ...

In this work, we explore the notion of 'turbocharging' in speed scaling systems, and ask whether this is sufficient to preserve the strong dominance property of FSP over PS. The answer turns out to be no, but the analysis yields useful insights into the design of speed scaling systems that ...

In this work, we describe how EdgeMaps provide a new method for integrating the visualization of explicit and implicit data relations. Explicit relations are specific connections between entities already present in a given data set, while implicit relations are derived from multidimensional data based on similarity measures. Many data sets ...

Quality of Service (QoS) can be provided in a Wireless Local Area Network (WLAN) using the Enhanced Distributed Channel Access (EDCA) mechanism specified in IEEE 802.11e. However, 802.11e WLANs are not widely deployed and not all WLAN vendors implement the 802.11e mechanisms. In this paper, we propose and evaluate an ...

Sensor nodes in a Wireless Sensor Network (WSN) are scattered in an environment to collect data. These nodes are limited in resources and cannot process the collected data or store it for long periods of time. Thus, the sensor nodes rely on routing protocols to relay the collected data wirelessly ...
