The concept of a phasor synchronized with the power system was introduced in the 1980s and standardized for the first time with the standard IEEE 1344. That measurement concept was further developed in the current synchrophasor standard, IEEE C37.118 that was completed in 2005. It is currently undergoing revision to fully define the measurement in all conditions including dynamic changes in the...

IEEE 802.11e Enhanced Distributed Channel Access (EDCA) is the most popular standard used in WLAN to support QoS for various real-time service flows. Based on DCF, EDCA introduces some new QoS parameters, which are defined by IEEE 802.11e standard. But how to adjust these parameters is still worth investigating. In the paper, we present a novel saturated throughput analysis of the IEEE 802.11e ...

Wireless ADHOC networks are self organized dynamic networks can share wireless channel without any established central control standard for IEEE 802.11. The most common protocols are AODV, DSDV, DSR, IRAODV in ADHOC used to ensure the data transmission among them selves. To meet the need of low power and low cost IEEE 802.15.4 standard was developed for sensor networks. In this paper we focus h...

This standard specifies the air interface of fixed (stationary) point-to-multipoint broadband wireless access systems providing multiple services. The medium access control layer is capable of supporting multiple physical layer specifications optimized for the frequency bands of application. The standard includes a particular physical layer specification applicable to systems operating between ...

The IEEE Standard 1057 (IEEE-STD-1057) provides algorithms for fitting the parameters of a sine wave to noisy discrete time observations. The fit is obtained as an approximate minimizer of the sum of squared errors, i.e. the difference between observations and model output. The contributions of this paper include a comparison of the performance of the four-parameter algorithm in the standard wi...

The Project Authorization Request (PAR) for the IEEE P1900.4 Working Group (WG), under the IEEE Standards Coordinating Committee 41 (SCC41) was approved in December 2006, leading to this WG being officially launched in February 2007 [1]. The scope of this standard is to devise a functional architecture comprising building blocks to enable coordinated network-device distributed decision making, ...

The development of IEEE 802.16 was started by the IEEE in 2001. After that it was revised several times and ended in the final standard IEEE 802.16-2004 which corresponds to revision D and is often called Fixed WiMAX [1]. It defines Wireless Metropolitan Broadband access for stationary and nomadic use. This means end devices can not move between base stations (BS) but they can enter the network...

We give a short description of an OFDM system, which is planned to combat the long Delay Spread, Multipath and interference. The system proposed includes adaptive modulations for Uplink and Downlink, adaptive bandwidth allocation and ECC. Purpose The document aims to introduce an adaptive system in the Downlink and the Uplink, which has the capabilities of combating Multipath and interference. ...

Body Area Networks are a solution to remote monitoring in order to acquire vital signals of patients. Actual sensors provide its own interface which makes more difficult to integrate them in a system. Using standardized protocols and interfaces increases the usability and the integration of different sensors, to achieve this goal the IEEE 1451 standard has been defined. This paper presents a pr...

We present in this paper a reliable optimized transmission of H.264 video streaming over IEEE 802.11e Wireless Mesh Networks (WMNs) based on a Cross-Layer Adaptive Enhanced Distributed Channel Access (CLA-EDCA) MAC architecture. The IEEE 802.11e EDCA offers a prioritized transmission to guarantee the minimum packets delay and drop rate needed for time bound applications, such as VoIP and Video....
