TL;DR: It is demonstrated theoretically and by means of an experimental system that the high peak-to-average ratio in OFDM can be exploited constructively in visible light communication to intensity modulate LEDs.
Abstract: In this paper wireless communication using white, high brightness LEDs (light emitting diodes) is considered. In particular, the use of OFDM (orthogonal frequency division multiplexing) for intensity modulation is investigated. The high peak-to-average ratio (PAR) in OFDM is usually considered a disadvantage in radio frequency transmission systems due to non-linearities of the power amplifier. It is demonstrated theoretically and by means of an experimental system that the high PAR in OFDM can be exploited constructively in visible light communication to intensity modulate LEDs. It is shown that the theoretical and the experimental results match very closely, and that it is possible to cover a distance of up to one meter using a single LED.

TL;DR: Indriya as mentioned in this paper is a large-scale low-cost wireless sensor network testbed deployed at the National University of Singapore (NU) which uses TelosB devices and it is built on an active-USB infrastructure.
Abstract: This paper presents Indriya, a large-scale, low-cost wireless sensor network testbed deployed at the National University of Singapore. Indriya uses TelosB devices and it is built on an active-USB infrastructure. The infrastructure acts as a remote programming back-channel and it also supplies electric power to sensor devices. Indriya is designed to reduce the costs of both deployment and maintenance of a large-scale testbed. Indriya has been in use by over 100 users with its maintenance incurring less than US$500 for almost 2 years of its usage.

TL;DR: The idea of VDE is very effective but straightforward simple and can be applied in very many configuration to provide several services.
Abstract: The idea of VDE is very effective but straightforward simple and can be applied in very many configuration to provide several services. It is a sort of Swiss knife of emulated networks. It can be used as a general virtual private network as well as a support technology for mobility, a tool for network testing, a general reconfigurable overlay network, a layer for implementing privacy preserving technologies and many others. A prototype VDE has been implemented and released as free software under the GPL licence.

TL;DR: The DETER testbed provides unique resources and a focus of activity for an open community of academic, industry, and government researchers working toward better defenses against malicious attacks on the authors' networking infrastructure, especially critical infrastructure.
Abstract: The DETER testbed is shared infrastructure designed for medium-scale repeatable experiments in computer security, especially those experiments that involve malicious code. The testbed provides unique resources and a focus of activity for an open community of academic, industry, and government researchers working toward better defenses against malicious attacks on our networking infrastructure, especially critical infrastructure. This paper presents our experience with the deployment and operation of the testbed, highlights some of the research conducted on the testbed, and discusses our plans for continued development, expansion, and replication of the testbed facility.

TL;DR: This work characterize the energy consumption of a visual sensor network testbed, namely Crossbow's Stargate, equipped with a wireless network card and a Webcam, and reports both steady-state and transient energy consumption behavior obtained by direct measurements of current with a digital multimeter.
Abstract: In this work we characterize the energy consumption of a visual sensor network testbed. Each node in the testbed consists of a "single-board computer", namely Crossbow's Stargate, equipped with a wireless network card and a Webcam. We assess energy consumption of activities representative of the target application (e.g., perimeter surveillance) using a benchmark that runs (individual and combinations of) "basic" tasks such as processing, flash memory access, image acquisition, and communication over the network. In our characterization, we consider the various hardware states the system switches through as it executes these benchmarks, e.g., different radio modes (sleep, idle, transmission, reception), and Webcam modes (off, on, and acquiring image). We report both steady-state and transient energy consumption behavior obtained by direct measurements of current with a digital multimeter. We validate our measurements against results obtained using the Stargate's on-board energy consumption measuring capabilities.
