This paper presents a solution to the power balance control strategy for WSN with collaborating heuristic. A distance between the weight factors and obtained nodes interference value is used to establish a useful interference model for enhancing the signal-to-interference-noise ratio (SINR). The utility function of the nodes residual energy and transmission rate is modeled by apply heuristic strategy. The optimal transmission power is obtained after several iterations of the heuristic algorithm.

The investigation of magnetic field strength variations over subterranean layers may reveal their locations on Earth’s surface and provide physical and geometrical characteristics. Magnetic studies were carried out around Gölcük caldera lake using proton magnetometers to identify subsurface volcanic structures. The acquired data were inverted using four different edge detection algorithms such as analytic signal, tilt angle, theta map, horizontal gradient. Afterwards, the results were used to determine the locations of the anomalous structures.

This paper investigates a cognitive radio network where a secondary sender assists a primary transmitter in relaying primary information to a primary receiver and also transmits its own information to a secondary recipient. This sender is capable of jamming to protect secondary and/or primary information against an eavesdropper and self-powering by harvesting radio frequency energy of primary signals. Security capability of both secondary and primary networks are analyzed in terms of secrecy outage probability.

Multiple-input multiple-output (MIMO) millimeter wave (mmWave) systems are vulnerable to hardware impairments due to operating at high frequencies and employing a large number of radiofrequency (RF) hardware components. In particular, nonlinear power amplifiers (PAs) employed at the transmitter distort the signal when operated close to saturation due to energy efficiency considerations. In this paper, we study the performance of a MIMO mmWave hybrid beamforming scheme in the presence of nonlinear PAs.

In this Smart Grid network, a Smart Grid node can receive and send data to Smart Grid centre through a Smart Grid network gateway. Hardware analysis and design of a Smart Grid node and Smart Grid network gateway are proposed with a goal of low cost and efficient energy consumption. Through a practical test of received signal strength measurement in an urban environment, the reliability of data communications of this Smart Grid wireless device has been proved. And finally, by using NS-2 simulation, packet loss and network delay time for different network topologies are evaluated.

This short book provides basic information about bioinstrumentation and electric circuit theory. Many biomedical instruments use a transducer or sensor to convert a signal created by the body into an electric signal. Our goal here is to develop expertise in electric circuit theory applied to bioinstrumentation. We begin with a description of variables used in circuit theory, charge, current, voltage, power and energy. Next, Kirchhoff ’s current and voltage laws are introduced, followed by resistance, simplifications of resistive circuits and voltage and current calculations.

Signals and Signal Spaces The goal of this chapter is to give a brief overview of methods for characterizing signals and for describing their properties. Wewill start with a discussion of signal spaces such as Hilbert spaces, normed and metric spaces. Then, the energy density and correlation function of deterministic signals will be discussed. The remainder of this chapter is dedicated to random signals, which are encountered in almost all areas of signal processing. Here, basic concepts such as stationarity, autocorrelation, and power spectral densitywill be discussed. ...
