The development of a reliable and energy-efficient protocol stack is important for supporting various WSNs applications. The penalty is increased complexity of the central node. This is a major problem because the central node is expected to have significantly more power and processing resources. On the distributed case, the coordinator (Distributed Coordination Function) only sends the active nodes to the sensors to keep the reliability and consumes less energy. As a result of this analysis, distributed mechanisms for QoS in WSNs built which extend wide area applications. This paper presents an energy-efficient aware of MAC application specific protocol with enhanced, integrated type in the distributed environment. Let to study the significant procedures for energy reduction compared to the available MAC protocols by cluster head election schemes as per the coverage issues. Most specifically, the cross-layer effects of routing, medium access, physical layers are considered. The proposal concentrates to point out and identifies the key problems of distributed MAC algorithm such as SLCH and MLCH election schemes focus towards the energy-efficiency designed for Wireless Sensor Networks (WSNs) with lemmas and theorems along with coverage strategies.

This paper addresses the performance analysis of Zigbee transceiver using IEEE 802.15.4 standard under 2.4 GHz frequency band in terms of Energy and Error over various fading channel conditions. Energy is a critical aspect in Wireless Sensor Network (WSN) for improved network lifetime. The multipath nature of the wireless sensor network channel imposes adverse effect on the received signal characteristics. These unreliable links increases the error level to a greater extent and hence, degrades battery life. In this paper, we investigate the energy efficiency of a Zigbee transceiver using Direct Sequence Spread Spectrum- Offset Quadrature Phase Shift Keying (DSSS-OQPSK) modulation under 2.4 GHz frequency band in a WSN. The Symbol Error Rate (SER) is computed for a Zigbee transceiver, and an expression for energy efficiency measurement is obtained. Simulation results on SER are obtained for AWGN, Rayleigh and Rician fading channels and used in energy efficiency computation. It is found that the energy efficiency of Zigbee transceivers is as low as 10% for Rayleigh channels, but it is over 90% for AWGN channels, when the received SNR is 10 dB, whereas, for Rician channels, it lies in between Rayleigh and AWGN, depending upon the fading level.

In order to provide the user's quality of service, the service level agreement between the customers and providers should be satisfied. However the resources available in a single datacenter are limited. Thus if a large demand is observed in a given time, a cloud provider is not able to deliver a uniform QoS. To avoid this scenario, I enable the application to scale it across multiple independent cloud datacenters by forming federated clouds. In such a case, from the customer's point of view it is always difficult to decide whose resources they should use. To handle this case a ranking mechanism is proposed which measures the quality and prioritize the cloud resources. In this work I propose a framework and mechanism for coordinator based advance reservation and ranking of cloud resources which allows the users to book resource in advance. Advance reservation provides guaranteed delivery of resources to the right customers at the right time.

Spatial modulation is a transmission technique that uses multiple antennas. It involves mapping of a block of information bits to two information carrying units, as a symbol chosen from constellation diagram and a unique transmit antenna number. The importance of Spatial modulation is that it increases overall spectral efficiency. In this paper we show the performance comparison of MIMO using Trellis Coded Spatial modulation, Space Time Block Coded Spatial modulation and New Trellis Coded Spatial modulation. And performance of each coding systems yields slightly different values. TCM concept is utilized to combat performance degradation of Spatial modulation in correlated channel conditions. Whereas the STBC-SM scheme is useful for high-rate, low complexity, emerging wireless communication systems such as LTE and WiMAX. The New SM-TC scheme offers significant error performance improvements over alternatives while having a lower decoding complexity for 2, 3, and 4 bits/s/Hz transmissions.

A novel method for managing and treating physical and psychological pain is the need of the hour. Although cybertherapy is at its development stage, a great potential can be reaped when it is moulded in the right way. Clinical virtual reality is found to be a promising way of distracting the patients from sensing the pain during medical procedures, physical rehabilitation or post-traumatic stress. There exists no single pain management methodology that is good for everyone, or even the majority of people. Research findings prove that pain has many causes and courses, and can impact individuals in a multitude of ways including the behavioral, physiological, emotional, psychological, social and spiritual levels. Though distraction through audio visual aids has a significant effect in decreasing the intensity of pain signals in the brain, the analgesic efficacy has to be well researched and improved. The perception of pain varies with factors such as age, ethnicity, sex and genetics. Increased nervousness of patients in virtual world, patients' confidentiality, subjectivity in effectiveness on individuals, array of pains to be handled with a single virtual platform and cost are the major barriers to be tackled. This paper discusses ways of providing such generic, acceptable and proven methods of cybertherapy. Such virtually painless world shall be greatly achieved only with close cooperation between technologists and medical experts.

This paper deals with the design and applications of digital differentiators. For real time applications it is mandatory that a differentiator should have as small an order as possible. Different procedures available for the design of FIR and IIR type digital differentiators are presented. The IIR Type digital differentiators are obtained by inversion and magnitude stabilization of the existing digital integrators. In some applications like controls, waveshaping, oscillators and communications require a constant 90° phase for differentiators. In this paper an attempt is made to study about the variation of phase angle of digital differentiators with the application of fractional delay. The use of digital differentiators for the detection of edges in an image, QRS detection in an ECG signal is illustrated. It has been observed that the digital differentiators have shown superior performance compared to the well known gradient method. With the proven efficiency of the differentiators in various applications, they have been implemented in hardware using Verilog.

Design of an algorithm for vehicle identification by recognizing the number plate is presented. This new vehicle identification technique consists of vehicle detection, plate localization and character recognition. Here, Genetic algorithm (GA) is employed at two levels: for detecting vehicle from traffic image and recognizing character from the number plate. Detection is based on contour and shape information. GA controls the window size to capture each vehicle in a separate widow. Connectivity and adjacency concepts are used to locate and extract number plate and its characters. A digital board (DB) with window panes is introduced to recognize each character uniquely. GA is adopted at the second level to map character pixels into the window panes as lines. For each character in the number plate, distinct feature vector is computed. Finally, a feature based matching is adopted for character recognition. Experiments have been conducted with images taken from various scenes and conditions and the detection rate is found to be 92.5 %. Experiments have conducted for recognition with LPR images taken at different conditions and the recognition rate is found to be 91 %. Detection time is linear function of number of objects in the input image. Potential applications include provisioning of vehicle parking facilities and campus security system for permitting authorized vehicles into the premises.

The larger size and complexity of software source code builds many challenges in bug detection. Data mining based bug detection methods eliminate the bugs present in software source code effectively. Rule violation and copy paste related defects are the most concerns for bug detection system. Traditional data mining approaches such as frequent Itemset mining and frequent sequence mining are relatively good but they are lacking in accuracy and pattern recognition. Neural networks have emerged as advanced data mining tools in cases where other techniques may not produce satisfactory predictive models. The neural network is trained for possible set of errors that could be present in software source code. From the training data the neural network learns how to predict the correct output. The processing elements of neural networks are associated with weights which are adjusted during the training period.

Computer architectures are expected to change to support Exascale computing in the near future. As energy and cooling constraints limit increases in microprocessor clock speeds and number of cores, computer companies are turning to parallel programming. Nowadays, parallel programming is achieved by increasing the number of processing elements in processor cores, increasing the number of processor cores itself and complicated parallel programming where programmer has the responsibility of allocating memory and synchronizing the communication between the processing elements as well as processor cores. It becomes increasingly difficult and expensive to design and produce shared memory machines with ever increasing number of processors. Increase in the number of processors is a major disadvantage when it comes to energy consumption. In this work, we present a new architecture for processor design based on pairwise balanced combinatorial interconnection of processing and memory elements. The proposed processor uses two operand instructions, so that the set of executable machine instructions is partitioned by these pairs. This kind of partition allows parallel processing of data-independent instructions. Since this partition is done at the compile time, the architecture extracts the instruction level parallelism without run-time overheads. We analyze and confirm the performance improvements through simulations. The suggested combinatorial arrangement gives set of architectures with various degrees of performance enhancement.
