Sensor nodes in wireless sensor networks (WSNs) are energy constrained. So, one of the major design challenges in WSN is minimizing consumed energy at the sensor nodes. Therefore, a number of routing schemes are designed that make efficient use of limited energy of the sensor nodes. These schemes typically use lowest energy path for data transmission. It has been observed that utilization of same path is not optimal as considered for network lifetime. Therefore, we propose a new scheme called balanced routing scheme, which transmit through multiple routes. The proposed routing scheme keeps a set of multiple paths depending on its weightage. However, weightage of the paths are decided from its proportion of utilization. The main objective of this paper is to implement balanced routing in simulator NS-2. In addition to this, performance of balanced routing is compared with the basic routing scheme, expected transmission count (ETX) scheme on the basis of energy consumption at the greediest sensor nodes. The result shows that, compared with ETX routing scheme, balanced routing scheme improves network lifetime by minimizing consumed energy at the nodes.

The generated power from renewable energy source is always fluctuating due to environmental conditions. In the same way, wind power injection into an electric grid affects the power quality due to the fluctuation nature of the wind and the comparatively new types of its generators. On the basis of measurements and norms followed according to the guidelines specified in IEC-61400 (International Electro-technical Commission) standard, the performance of the wind turbine and thereby power quality are determined. The power arising out of the wind turbine when connected to a grid system concerning the power quality measurements, are: active power, reactive power, voltage sag, voltage swell, flicker, harmonics, and electrical behavior of switching operation. These are measured according to national/international guidelines. This paper clearly shows the existence of power quality problem due to installation of wind turbines with the grid. In this proposed scheme a FACTS device {STATIC COMPENSATOR (STATCOM)} is connected at a point of common. The FACTS Device — Static Compensator (STATCOM) control scheme for the grid connected wind energy generation system to improve the power quality is simulated using MATLAB/SIMULINK. The intended result of the proposed scheme relives the main supply source from the reactive power demand of the load and the induction generator. From the obtained results, we have consolidated the feasibility and practicability of the approach for the applications considered.

Power system stabilizers (PSS) must be capable of providing stabilization signals over a broad range of operating conditions and disturbance. Traditional PSS rely on robust linear design method in an attempt to cover a wider range of operating condition. Expert or rule-based controllers have also been proposed. Recently fuzzy logic as a novel robust control design method has shown promising results. The emphasis in fuzzy control design center is around uncertainties in the system parameters and operating conditions. In this paper a novel Fuzzy Logic Power System Stabilizer (FLPSS) design is proposed. A proposed FLPSS basically utilizes two signals; namely change in rotor angular speed and rate of change of angular speed. A proposed FLPSS provides a good damping over a wide operating range. The effectiveness of the proposed fuzzy stabilizer is demonstrated by a digital computer simulation in MATLAB 7.0/SIMULINK of a single machine and a resistive load power system.

Carotid signal obtained from the patient with the help of piezoelectric sensor may be used to assess the patient's cardiac activity. Many methods based on various principles have been developed to measure the carotid pressure waveform. A piezoelectric sensor based system has been designed, developed and placed on the subject's carotid artery. The piezoelectric sensor has a transducing element adapted to sense movement due to carotid pulse and produce piezoelectric signal data in response thereto. The real time data of carotid pulse waveforms of ten human subjects in various body postures are acquired using wired as well as wireless system and filtered using MATLAB software. RR period and pulse amplitudes are quantified from the recordings by visual inspection. The technique may be used to measure and manage G stress effect on aircraft pilot.

Nature has always been an inspiration for developing new models using technology. An emerging and promising field which has natural phenomena and their principles as its roots is Neural Computing. In an era of information processing, the most challenging yet efficient processing model offered by the nature, for technological inspiration, comes in the form of human brain. This inspiration brings along with it an opportunity for technology to unite with the abnormal natural cases and enable them to operate correctly. This paper explores the potential of this field which has the capability to open new horizons and generate new possibilities. Although technology can't replace nature for gifting life, it can use Neural Computing to support and guard it in times when nature sees no self-cure. A new methodology under Neural Computing, named as Coordinated Artificial Neural Network (CANN) is proposed where nature and technology work in unison. CANN is capable of replacing parts of the damaged human nervous system, thus supporting normal body processes and giving a new life. The paper concludes with a discussion about the power of this field, especially CANN, and its feasibility.

Internet has emerged as a medium to connect people across the world for emailing, conferencing, on-line trading, gaming and so on. Internet of Things (IoT) is aimed at making daily lives more sophisticated, flexible and highly reachable to any objects across the world. In IoT, physical objects such as home appliances, vehicles, supply chain items, containers etc. will have digital identities and they will be context aware to sense the environment around them and interact with each other. The objects will be able to respond with the information useful for real-time decision making such as safely changing the lane while driving, automatically switching off the lights in a room when no one is around and so on. Effective monitoring of the environmental conditions to control issues such as pollution, disaster and global warming is another important objective of IoT. For IoT, objects are required to be made smart by embedding intelligence into them using technologies such as Wireless Sensor Networks (WSN) and Radio Frequency IDentification (RFID). In addition to mobile communication technology, Internet will be the primary backbone of the communication channel of IoT. As Internet is a public (and insecure) channel, security is an important concern in IoT infrastructure to communicate the voluminous information across the globe in a secure and timely manner. In this paper, we discuss the potential scope of IoT, the major technologies involved in IoT infrastructure and some important application domains for IoT. We also discuss the security and privacy issues of two important technologies of IoT, namely, WSN and RFID.

Grid computing provides a high performance computing platform to solve applications with large number of independent jobs. However, user jobs developed for grid might be small and of varying lengths according to their computational needs and other requirements. In fact, it is a big challenge to design an efficient scheduler, but there exists some grouping based job scheduling strategy that intends to minimize total processing time by reducing overhead time and computation time, and on the other hand maximizing resource utilization than without grouping based scheduling. Further analysis and research on job scheduling can be carried out to enhance the performance of grouping based scheduling algorithm in grid computing. This study intends to achieve better performance by extending the concept of grouping based job scheduling. Therefore, this paper proposes “A modified grouping-based job scheduling in computational grid” with the objective of minimizing overhead time and computation time, thus reducing overall processing time of jobs. The work is verified through simulation and the results obtained shows that the proposed grouping-based scheduling algorithm is better than, others.

The monopulse antenna tracking system is the preferred choice where higher pointing accuracy is required because of its inherent advantages. There are three possible configurations for realizing monopulse tracking system. One of the configurations is called single channel monopulse tracking system as it requires only one down converter chain. In this configuration, the sum and both (AZ/EL) error signals are combined to reduce the required number of down converters. A single channel monopulse processor is vital subsystem of a single channel monopulse tracking system which extracts the pointing error information from the IF signal. During the development, these processors need to be tested for its functionality in the laboratory which requires a stimulus generator. The stimulus generator generates an IF signal which mimics the real time signal and can be used for debugging and functional verification. This paper presents a simple approach for realizing a stimulus generator for single channel monopulse processor. A stimulus generator has been developed using this approach and has been used for laboratory testing of a single channel monopulse processor. The tested single channel monopulse processor has been successfully integrated with the earth station antenna tracking chain at NRSC, Hyderabad, India and used for tracking the LEO satellites.
