This paper proposes a context aware routing in distributed sensor network for data gathering and dissemination. A Distributed Sensor Network (DSN) is composed of intelligent sensors that are geographically dispersed in the region of interest and interconnected through a communication network. The (acoustic, seismic, and infrared) data by leaf sensor nodes are transmitted over the network and integrated...
Among all physiological signals, present in the human body electroencephalogram (EEG) signals are accepted and productive in the application of mental state detection of a person. Electrical impulses produced by nerve firings in the brain diffuse through the head and can be measured by electrodes positioned on the scalp. EEG provides a coarse analysis of neural activity and has been utilized to non-invasively...
The Internet is going through several major changes. It has become a vehicle of Web services rather than just a repository of information. Web Services are heterogeneously developed software components invoked over the network viz. the Internet, Web Services are the most famous implementation of service-oriented architectures (SOA) that has brought some challenging research issues related to security,...
Knowledge of incidence and prevalence of a disease is vital in Community Medicine to control a disease. It is important in Internal Medicine for clinical diagnosis and presumptive treatment on a probability model. Prevalence informs the total case load at a given time. Incidence yields a pointer to extent of attention required and choice of measures. Initially K-means clustering is used to group the...
World is seeing a rapid growth in mobile communication and along with it is becoming difficult to maintain secrecy. There are device developments going on to mitigate this problem. The paper proposes a Mobile detection device which can be used as a metal detector to detect cell phones from the range of few centimeters to few feet's depending upon the Cell phones transmission strength and other parameters...
Improving network lifetime is the fundamental challenge of wireless sensor networks. One possible solution consists in making use of mobile sinks. Sink mobility along a constrained path can improve the energy efficiency in wireless sensor networks. However, due to the path constraint, a mobile sink with constant speed has limited communication time to collect data from the sensor nodes deployed randomly...
In this paper, we address the problem of joint transceiver optimization for downlink of multiuser multiple-input, multiple-output systems employing improper constellations such as binary phase shift-keying (BPSK) and M-ary amplitude shift-keying (M-ASK). Proposed are novel joint linear transceivers that minimize the total mean squared error (TMSE), subject to a total transmit power constraint. The...
A method to both reduce energy and improve performance in a processor-based embedded system is described in this paper. Efficient utilization of on-chip memory space is extremely important in modern embedded system applications based on microprocessor cores. In addition to a data cache that interfaces with slower off-chip memory, a fast on-chip SRAM, called Scratch-Pad memory, is often used in several...
SQL Injection poses a serious security issue over the Internet or over web application. In SQL injection attacks, hackers can take advantage of poorly coded Web application software to introduce malicious code into the organization's systems and network. The vulnerability exists when a Web application do not properly filter or validate the entered data by a user on a Web page. Large Web applications...
The function of the nodes in Wireless Sensor Networks which are connected via wireless links are sensing the events when placed in the environment and sending those sensed data to the base station. Routing, power management, and data dissemination protocols have been employed for WSN. In WSN where nodes are mobile and communicate directly to base station like MANET (Mobile Ad-hoc Network), the Proactive...
In this paper, a meta-heuristic approach called Adaptive Hybrid Harmony Search algorithm (AHHS), which is a variant of recently developed Harmony search optimisation algorithm is proposed. The harmony search is basically conceptualized using the musical process of searching for a perfect state of harmony. The proposed algorithm is hybridised with a customised neighbourhood search algorithm called...
The paper describes the various features enhancing the feature of power efficiency in the wireless sensor node for monitoring the industrial processes. The sensor node is deployed to monitor the process parameters in a remote location. The industrial processes are unique in their requirement of highly reliable operation in harsh environments. The robust, high efficient and reliable sensor node is...
In this paper we present a Mobile Ad-Hoc Network (MANET) which securely transmits Audio data. Even though studies on network security has been done before, secure transmission of audio has not been given much importance since both audio and Ad-Hoc network are both complex to handle. So some simple and efficient methods are required to encrypt Audio data. We aim to provide double security by encrypting...
Spatial queries are becoming integral part of many mobile applications. With revolutions in GPS and GIS, the location based spatial queries are exploring spatial information to mobile users to a large extent. Finding nearest neighbor, shortest path to the destination, retrieving skyline objects and spatial skyline keyword query are some of commonly used queries on road networks. In this paper we introduce...
The increasing incidence rate and mortality rate of cancer have stimulated the research for prevention, early diagnosis and appropriate treatment. DNA ploidy status of tumor cells is an important parameter with diagnostic and prognostic significance. In the current study DNA ploidy analysis was performed using digital image processing techniques. A normal human cell contains 46 chromosomes. In nonmalignant...
This paper presents a way to bring augmented reality in the field of automation. By bringing augmented reality in the field of automation it increases the interactiveness in controlling devices and machines. Virtual 3D models are created using a modelling software and plugins are used to communicate from the modelling software to the devices to be controlled. The virtual 3D models are three dimensional...
This paper describes a novel method of detecting an object using signature library which is very fast as compared to traditional methods. The traditional method deals with template matching based object detection. It involves sliding window based approach, which is very costly and time consuming. The template matching based object detection method searches for the object in all possible image sub-windows...
Human visual system can identify larger defects taking place on the woven fabric. But it is very difficult to classify and identify the small fabric defects by a human inspector. In the textile industries the defect detection by a human inspector affects the production tremendously. Thus this paper gives a solution of this problem by developing an automatic fabric defect detection system, based on...
Partial discharge (PD) measurement is used for condition monitoring of insulation in high voltage equipments. Extraction of PD pulses buried in noise and interferences is a challenging task encountered in PD measurement. Recent research shows that second generation wavelet transform (SGWT) can potentially be employed for extracting PD pulses from severe noise and interferences. In this work, an SGWT...
