The ever-increasing demand of electrical energy makes it necessary to develop an efficient load demand management system for the electricity grids so that it gets converted into Smart grid. There are several standardized wireless communication technologies available for various smart grid applications among which (WiMAX) is seen as a well recognized technology able to fulfill the requirements of smart grid's applications namely wide area connectivity and the quality of service (QoS) differentiated services. This paper proposes a WiMAX based traffic priority model for smart grid connecting Neighborhood Area Network (NAN) and Home Area Network (HAN) serving five different applications. Parameters namely overall network delay, throughput and network capacity are studied using OPNET 14.5 and also the implications of the cell size, number of users and interpolling interval (IPT) are analyzed.

Steganography is the art of hiding the existence of data in another transmission medium to achieve secret communication. Steganalysis is the method of discovering the secret message. These two areas are very useful in secret communication. In this paper the proposed scheme is an image steganography that can verify the integrity of the secret information which is transmitted to the receiver. Integrity is the method to verify whether the information is altered by the attacker. The process embeds the encrypted secret message into the cover image with the veracity verification code. To verify the integrity the veracity verification code is used. Two special AC coefficients are used to create the veracity verification code. The Bit Error rate (BER) and the Peak Signal to Noise Ratio (PSNR) calculation are performed.

Hardware implementation of FIR Filter has major applications in Analog and Digital areas. In digital signal processing FIR filters are used in separation of signals and in signal restoration purpose. The filter in the existing method is designed using multiplier technique which increases the area, delay, power and also designed using multiplier less technique by using binary input which requires much scaling. It is aimed to design a reconfigurable FIR filter which reduces area, delay also improves the speed and performance. In this method the input is converted into its residues by introducing residue number system and encoded as thermometer code which provides a simple means to perform modular inner product computation. The proposed work is designed using distributed arithmetic algorithm by introducing inner product computation method. The reconfigurable FIR filter is designed using reconfigurable look up table. The reconfigurable filter is coded using Verilog code and synthesized using Cadence Software.

Detection of blood volume change in the skin by using Photoplethysmogram (PPG) sensor is based on the principle that hemoglobin in the blood absorbs infrared light than the other tissue. Favorable optical window is around 990 nm range. The reflectance type photoplethysmographic sensor is designed using two different detectors. Objective is to compare the response of PPG sensor by using Light Dependent resistors (LDR) and OPT101 as a detector. Signal is recorded by placing the sensor on a finger tip for wavelength ranging from visible to near IR (400 to 1000 nm) range. It is observed that the PPG signal captured using LDR is around 660 nm wavelength but for the OPT101 response is 500 nm to 1000 nm. That is OPT 101 can be used to capture PPG in visible and infrared region. Brain mapping using optical sensor OPT101 is preferable for the measurement of blood volume and blood flow. For source of 660 nm, LDR or OPT 101 can be used to detect the peripheral pulse. LDR is not suitable for the measurement in infrared range.

Low Power Transmitter design requires to optimize the energy efficiencies of key building blocks including Voltage Controlled Oscillator, Mixer, and Power Amplifier (PA). Traditional Power Amplifier design for low power application use various classes of amplifiers such as Class A, Class AB, Class E to avoid output filters that degrades the output efficiency. Class-E PA is a nonlinear switching type PA which can ideally achieve 100% efficiency. Generally the output of the Power Amplifier should match with antenna's 50Ω resistance; this high efficiency has spurred many research interests on the design and analysis of Class-E PAs. The aim of the paper is to design a microwave PA which works in the narrow band range of 2.35-2.45GHz. This paper presents a new Class-E PA with a π-matching output network which produces increased efficiency. The proposed circuit consists of power amplifier stage along with the Pre-driver stage. The Pre-driver stage is an indispensable stage when we refer to the rest of power amplifier. The N-Channel Field Effect Transistor (NFET) Inverter with a serial inductor reduces the power consumption of the switching capacitance of the PA stage is used as the pre driver stage. The PA stage realised by NFET. In order to increase the efficiency of PA a parallel inductor is introduced to the conventional Class-E PA structure. The Proposed structure needs a supply voltage of 0.5 V. The structure is simulated using the Advanced Design System (ADS) simulator. The output of the simulator produces graph of current with time and voltage with time. The efficiency of the PA is also plotted using ADS. It is possible to achieve increased efficiency when the width of the transistor is reduced. The inductor introduced at the output stage also has an impact on the efficiency of the PA. The proposed PA finds applications in Bio-Telemetry, short distance communications etc.

MANET is a type of infrastructure less wireless communication network/system that can be set up at anytime, anywhere. In MANET each and every process consumes power. Power consumption is one of the most crucial design concerns in Mobile Ad-hoc networks as the nodes in MANET are battery limited. To increase the life time of nodes as well as network energy management is necessary. The life time of a node can be increased when less power is consumed by the nodes during active as well as during inactive communication. In order to increase the life time of a node, traffic should be routed in a way that, power consumption is minimized. DSR is a routing protocol used in MANET. It uses two mechanisms in routing Route Discovery and Route Maintenance. During route discovery it selects the path to establish communication between source and destination. The flooding of routes creates overhead in routing traffic which cause extra consumption of energy. In this paper anew route discovery mechanism is proposed to conserve the energy of nodes during route discovery and data transmission phase compare to original DSR protocol. The proposed work is verified using NS-2 simulator.

Measurement of blood volumetric changes in human body by photoplethysmographic sensors is used in present study. Objective is to measured different parameters that are heart rate, respiratory rate, BP. PPG signal is acquired by PPG sensor, microcontroller and RS 232. The acquired PPG signal is displayed in MATLAB. Frequency domain analysis of PPG signal shows a two peaks first at around 0.25 to 0.35 Hz and second at around 1 to 1.5 Hz. FFT at 1Hz relates to 60 BPM and FFT at 0.25 Hz relates to 15 respiratory cycles per minute. For BP Measurement, the pulse height of PPG is proportional to the difference between the systolic and the diastolic pressure in the arteries. The standard blood pressure monitoring instrument is used to calculate correlation coefficient. The arterial blood pressure is calculated based on these coefficients. PPG signal is used to detect blood pressure pulsations in a finger and achieved an accuracy of (0.8 ± 7) mmHg and (0.9 ± 6) mmHg for systolic and diastolic pressure, respectively. The developed PPG based method can be used as a noninvasive alternative to the conventional occluding-cuff approaches for long-term and continuous monitoring of blood pressure, heart rate and respiratory rate.

This paper presents a colour image encryption algorithm based on cross-coupled chaotic map and fractional order chaotic systems. Firstly the algorithm employs the cross-coupled chaotic skew tent map to perform the shuffling operation, and then uses the fractional order versions of Lorenz's system and Chen's system to disturb image pixel intensity values. Fractional order extensions of the chaotic systems provides a much larger key-space than their original integer order versions. The encrypted image exhibits uniform histogram and a very high entropy for all the three colour channels. Also, the property of zero correlation is satisfied by the intensity values of adjacent pixels in each channel of the encrypted image. Moreover, the algorithm possesses a key-space which is large enough to resist all possible kinds of statistical attacks. Theoretical analysis and experimental results thus demonstrate that the proposed scheme has an excellent efficiency and satisfactory security attributes. However, solving fractional order differential equations is a computationally heavy process. Some efficient computing techniques are successfully employed to deal with this problem, so that the encryption-decryption process is executed reasonably fast.
