In the communication era congestion is the bottleneck which degrades the performance. In Ad hoc networks due to infrastructure less character there is no guaranteed bandwidth and node mobility. The traditional TCP variants were good for wired environment, whereas in Ad-hoc networks there are lots of other factors to be considered. We are comparing the traditional TCP Reno and its new variant HSTCP...
The voltage signal disturbances may lead to the difficulties viz. heating, device aging, etc. Enhancement of the devalued supplied power voltage is a prime task that needs identification and also the classification of the noise. Therefore, for disturbances namely voltage sag, transients, swell and harmonic voltage disparities, identification by Hilbert-Huang transform and classification by Support...
Image preprocessing and image enhancement plays a critical role in medical image processing. Considering the case study of breast cancer detection, it was found that there are various schemes of optimization techniques which is either training based or leads to recursive iterations leading to computationally complex process. Hence, the proposed system implements a unique and novel optimization technique...
The term cryptography which means “secret writing” has become the foundation primitive in providing security for many communication applications. In many applications, particularly in Group Communication, there is a need to hide secret data like passwords, encryption key, recipes etc. Here, efficient key management protocols are required to provide security for group's secret data, because it is very...
From the early days, images are being generally accepted as a proof of occurrence of the past events. The availability of low cost hardware and software tools, makes easy to create and manipulate digital images with no obvious traces. This has led to the situation where one can no longer take the integrity and authenticity of the digital images for granted. In many cases, the images are copied from...
The reliability of Wireless Sensor Networks (WSNs) is affected by faults that may occur due to various reasons such as communication link failure, malfunctioning hardware, software glitches, dislocation or environmental hazards. A WSN that is not prepared to deal with such situations may suffer from a reduction in network lifetime or lead to hazardous consequences in critical application contexts...
Iris Recognition is increasingly being used as the main method for biometric authentication since it is highly reliable and accurate. It considers the unique patterns of the iris to identify personnel by applying pattern recognition techniques. As the usage of iris recognition system increases, the number of iris code to be stored and retrieved for matching in large database of irises increases proportionally...
This paper presents the study on the effect of a rectangular slot defective ground structure on a rectangular microstrip patch antenna operating at 2.4 GHz. The rectangular microstrip antenna with rectangular defective ground structure(DGS) is simulated using HFSS software. The effect of defective ground structure on the rectangular microstrip patch antenna is observed by varying the length of the...
The data mining techniques are employed for efficient and real time analysis of Weather and Climate data. The main goal of studies on Climate is that users e.g. farmers, Scientist, decision & policy maker etc., from different industries e.g. Agriculture, Scientific, Aerospace etc., is required to understand the importance of various changes in weather and climate parameters like rainfall, humidity,...
Substantial amount of research has been performed on automated tool status monitoring systems. The research has tended to focus on the development of Tool and work Surface Texture Monitoring using machine vision. However, there has been relatively less effort to monitor surface texture. This paper presents machine vision system, capable of providing surface texture information in Turning Inconel 718...
The interest of the sports analytics has significantly grown higher recently. Manual analysis of the sports videos like extracting required shots and motion tracking of the player is very time consuming. Automatic motion tracking of players is useful for broadcasters and sportsmen's at individual level of player so can improve quality of game and automatic shot detection and extraction useful to extract...
Image processing has been proved to be a powerful tool for analysis in numerous fields and applications. Timely recognition of diseases is the main challenge in agriculture science. The present method uses naked eye observation to detect diseases which is less accurate and expensive for large farms. In this paper the system is proposed to identify and classify the diseases in carrot vegetable using...
With the proliferation of advanced telecommunication technologies and mobile computing, the transportation system is also getting smarter. There has been a good amount of research work done in the past decade to enhance the user experience in transportation facilities, however the existing systems are found to be less emphasizing on the traveler's requirements. In order to align the traveler's requirements...
Cloud Federation is an emerging technology for the effective utilization of cloud resources. Effective management of resources is very much required in order to increase the profits of individual CSPs in the federation. Hence, it is of crucial business value for a cloud provider to develop an effective mechanism so that the resource management is efficient in the cloud federation scope. In this paper,...
In today's fast growing and increasing complex world of VLSI circuits, test quality has significant effect on the quality of the product. A malfunctioning circuit is a result of design flaw, manufacturing defects or both. Testing is used as a measure to estimate the quality of design. High quality testing minimizes defect-per-million (DPM) and thus can significantly reduce manufacturing costs and...
The electric power is transmitted and distributed to the consumers along the transmission and distribution lines. Performance of distribution line becomes inefficient due to reduction in voltage magnitude and increasing distribution losses. Distribution system contributes the greatest amount of power loss. Distribution system reconfiguration is one of the techniques to minimize the losses. The standard...
The main aim of the biomedical signal processing is to extract information from a biological signal. Biomedical Signal Processing begins with the temporal record of the biological event of interest. Correlators give the Statistical Relationship between the two random variables or two sets of data. Correlations are useful because they can indicate a predictive relationship that can be exploited in...
The Adder is the important part in any processor/controller design. Till date there are a plenty of 1-bit full-adder circuits which have been proposed and designed. In this paper we have a analytic and comparative description of various full adder circuits, considering various constraints like power consumption, speed of operation and area. The circuits are designed in the virtuoso platform, using...
In most computer and communication networks, nodes share common medium for transmitting data. The Medium Access Control (MAC) protocol is responsible for regulating access to common medium. The use of Wireless Sensor Networks (WSNs) has been widely accepted in almost all the walks of life. As the nodes in WSN have limited power source, energy efficiency plays an important role. To increase the lifetime...
The thought of taking a perfect image gives way to a plethora of ideas which work towards improving the image quality using Image Stabilization. Currently, the methods used for Optical Image Stabilization(OIS) use Motion sensors and detect vibration and correct for any jitter using VCM (Voice coil motors).The concept of the proposed work is to simulate a MEMS gyroscope and monitor the system to detect...
