The IEEE 802.15.4 standard has been attracting strong interest, but in the academic community so far very little research related to the IEEE 802.15.4 MAC has been evaluated experimentally, with real hardware under realistic conditions. This is mainly due to the fact that a stable, open-source IEEE 802.15.4 MAC implementation has been unavailable for a long time. Vendor-specific implementations...

THE INCREASED USE of embedded predesigned reusable cores necessitates a core-based test strategy, in which cores are tested as separate entities. The goal of IEEE Std 1500-2005 (Standard Testability Method for Embedded Core-Based Integrated Circuits) is to simplify reuse and facilitate interoperability for testing core-based system chips, especially if they contain cores from different sources....

The IEEE 1599 standard offers new potentialities to the most common and effective synthesis systems for the manipulation of timbres. This articles describes how sounds produced in a particular synthesis system can be managed in a complete and intuitive environment thanks by interacting with files designed according to the IEEE 1599 standard and with their contents. It is shown how easy it is to...

An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. The architecture of the IEEE 802.11 WLAN is designed to support a network where most decision making is distributed to the mobile striation. The first, IEEE Standard 802.11a, is an orthogonal frequency domain mul...

In this paper, we propose a real-time transcoding system to generate contents for mobile networks with QoS provisioning. Video transcoding is widely used to change storage formats. However, as far as the authors know, it has not been proposed to generate real-time contents. Although the philosophy in this paper can be extended to alternative video sources (all major open TV channels are broadca...

Wireless sensor networks (WSN) consists of light-weight, lowpower and small size sensor nodes (SNs). They have ability to monitor, calculate and communicate wirelessly. In this paper we present a performance evaluation of ZigBee which is IEEE 802.15.4 standard, including the Physical (PHY) layer and Media Access Control (MAC) sub-layer, which allow a simple interaction between the sensors. We p...

This article is devoted to the development of scrambler circuit. Nowadays, new WiFi standard IEEE 802.11 being put into operation, so that there a huge need in modern, energy-efficient algorithms, which will be used data transmission. Consequently, some circuits, could implemented for are described with its comparison. In addition, an example Python given readers use it their researches.

Abstract This paper investigates the extent to which IEEE 11073 SDC standard family loads a communication network. An provider/consumer based on SDCLib/J from SurgiTAIX AG was implemented as test environment and several different scenarios were run in order gather data sets for use cases. The analysis of thus acquired measurements shows linear, predictable growth network utilization almost all ...
