This letter proposes a novel data gathering scheme for wireless sensor networks (WSNs) that limits the energy expenditure, and hence, prolongs network lifetime. Data gathering is modeled as an auction where a node broadcasts its own result only if it is higher than the maximum already-broadcasted result by other nodes. For a WSN of 100 nodes, the m...

This paper considers a communication model containing two users that exchange their information with the help of multiple parallel relay nodes. To avoid interference at these common nodes, two users are required to transmit over the different frequency bands. Based on this scenario, the achievable rate region is initially derived. Next, an optimiza...

Bounds on the achievable rate of a Gaussian channel in the case that the transmitter knows the interference signal but not its fading coefficients are given. We generalize the analysis which were studied in many other references such that their results are special cases of our analysis. We enforce our bounds by simulations in which many numerical...

This paper presents a novel practical method for evaluating the local sensing performance of the participating users in collaborative spectrum sensing in cognitive radio networks. The proposed method considers data delivery as a base to evaluate the local sensing performance of each user. Moreover, the proposed method does not rely on any prior inf...

An important part of the Jordanian government strategy to overcome the energy challenge is to diverse to renewable sources, such as photovoltaic (PV) solar power. In this context, many projects have been initiated by both government and private sector. The southern part of the country has an outstanding potential for such projects. This study inves...
Article
One of the necessities to get the best performance of photovoltaic (PV) solar modules is monitoring its parameters. The data acquired from monitoring, are significantly required for research purposes and development activities in universities and research centers. In this paper, a proposed technique is developed for remotely monitoring of most comm...

A new approach for studying the performance of single-mode optical fiber surface plasmon resonance sensor for refractive index sensing is presented. Intensity interrogation technique is used to observe and examine the effect of changing the value of the operating wavelength, within the single-mode operation region, on sensor performance. Effect of...

In this paper, a study of the lightning phenomenon and its harmful effect on Aqaba pThermal Power Station (ATPS), located in the south-western border of Jordan, is presented using the Electromagnetic Transients Program – Alternative Transients Program (EMTP- ATP). This study has been arisen due to an installation need of appropriate lightning arres...

This paper investigates setup optimization of Spatial Modulation (SM) systems. Specifically, the optimal pair of the number of the transmit antennas and the modulation order, for a given spectral efficiency, that minimizes the error rate at the receiver has been discussed. Interesting results regarding the behavior of bit error rate and symbol erro...

The authors discuss the importance of using the singular value decomposition (SVD) in computing the capacity of multiple input multiple output (MIMO) and in estimation the channel gain from the transmitter to the receiver. Examples that show how the SVD simplifies computing the MIMO channel capacity are discussed. Numerical results that show what f...

We derive the optimal power allocation for Gaussian two users broadcast channel. To find the optimal power allocation between the two users, two optimization schemes are considered. In each optimization scheme, an analytical expression for the optimal power allocation between the two users is derived. The first optimization criterion finds the opti...

In this work, we consider a relay channel model, with an out-of-band relay, in which the interference signal is available non-causally only at the source. The case in which the relay operates over different frequency bands with respect to the direct link is investigated. In particular, the source-destination (S-D), the source-relay (S-R) and the re...

In this paper, an industrial electrical network that contains some of industrial loads connected through a converter, which is a harmonic source in the power systems, is modelled. The Alternative Transient Program (ATPDraw) is used to simulate this problem, which is considered as a common power quality problem occurring in most of industrial networ...

V příspěvku budou prezentovány výsledky změny výkonu, který je přenášen jádrem step-index málovidového optického vlákna v důsledku ohybu. Tyto výsledky jsou získané za předpokladu, že při ohybu dochází pouze k redistribuci výkonu mezi jádrem a pláštěm vlákna. Dále bude studováno Chování jednotlivých vedených vidů z hlediska ohybových ztrát.
