Design and analysis of the security assessment framework for achieving discrete security values in wireless sensor networks

The paper presents a ready-to-use security assessment framework for wireless sensor networks (WSNs). The parameters in the proposed security assessment framework perform independent security assessment of WSNs and of their applications. Our proposed framework uses actual responses of the entities (such as nodes, communication link and network response) to assign numerical values for security assessment of WSNs. The method for calculating the optimal values for each security parameter of the framework is also discussed. Our proposed framework is designed to avoid unwanted impacts of the complexities of security algorithms, communication protocols and strong cryptography. Usually, the complexity of algorithms disguises the actual assessment of the WSN, but the independence of the proposed framework from these security-disguising objects makes this framework better than other assessment frameworks in terms of scalability.

Development of Wireless Sensor Networks for Smart Civil Structures and Highway Safety

We propose a unique model Wireless Sensor Networks for Intelligent Spaces (WIS), for Smart Civil Structures, which aims to cover utility of WSN in Intelligent Structures. WIS uses smoke detectors that monitor different parts of the building and communicate to track the spread of the fire. WIS utilizes stress and motion sensors, built into the civil structures, in order to monitor the health of such large structures. We present a novel model of Vehicular Sensor Network (VSN), known as Sensor-VISION (sVISION) which extends the idea of WSN in Intelligent Transportation System (ITS). Few basic MAC protocols for WSN like Low Duty-Cycle (LDC) protocols and Wake up concepts, Sparse Topology and Energy Management (STEM) and Sensor-MAC (SMAC) have been discussed and two of them have been simulated using MATLAB. Using Crossbows Basic WSN kit, we have obtained real-time sensor values that can be extended utilizing application-specific sensors.

Implementation of line tracking algorithm using Raspberry pi in marine environment

In recent days it is necessary to maintain continuous surveillance of underwater transmission lines or oil pipelines. For such purpose, we require an underwater vehicle rover capable of tracking these wires or pipelines and detect the fault if it occurs. For this purpose we have designed an intelligent quad leg rover. Image processing as a key deployed for tracking and tracing the fault or damage. Houghs Transformation is used for the detection of the wire, and threshold levels were also set of the underwater environment for vehicle to focus only on wire. For tracking the transmission lines and proper navigation, we have used a masking technique. The system is implemented on Raspberry pi (Broadcom BC2835) as well as Intel Core Processor T7250 to improve and analyze the performance in terms of size and mobility. The results presented in this paper are simulated on Intel T7250 processor and on raspberry pi. It helps in evaluating the response time of the raspberry pi when compared to any other processors in terms of computation and robustness.

Web Support System for Business Intelligence in Small and Medium Enterprises

Last decade belongs to business intelligence (BI) because it is one of the few concepts that have actually lived to the expectations. Not only the businesses have adopted it but also have reaped the fruits out of it. But the cost of BI solutions is very high and has restricted small and medium enterprises to use BI solutions. The human resource is also limited and resultantly expensive in this field. This research proposes a web support system for business intelligence which provides automated data mapping and loading from user application to BI framework and also validates it. The system also assists users in getting the outputs in terms of reports and dashboards. The implementation of the proposed framework demonstrates convenience of use and effective cost saving as it does not require any technical expertise. The beauty of this web support system is that all the steps are menu driven and any non-technical user can get hold of it easily.

Wireless Sensor Networks for Developing Countries

To improve the sampling frequency of water diversion to distributary canals and to improve equity of distribution and data handling we have developed a smart electronic water meter based on ultrasonic sensors and GPRS modem to frequently record and transmit the water diversion data to a centralized server. The server processes the data to extract useful information for example seasonal cumulative water deliveries and discharge time series. The Wireless Sensor Node (WSN) inspired design is extremely low-power, field deployable and scalable with respect to cost and numbers. This paper, reports the first steps towards practical realization of a smart water grid in the Indus river basin, conceptualized by the authors in previous theoretical studies.

Quadrature Phase Shift Keying modulator & demodulator for Wireless Modem

Digital modulation is a process that impresses a digital symbol on to a signal suitable for transmission on a wired or wireless medium in order to receive that signal at receiving end correctly with out any loss of information. Quadratic phase shift keying (QPSK) modulation technique is the most widely used modulation scheme in modern digital communication system; it provides high performance on bandwidth efficiency and bit error rate. In this paper the complete model of Quadrature Phase Shift Keying (QPSK) modulator and demodulator has been developed. The model has been simulated in Matlab using Simulink. Complete results are tested and verified. In final hardware design and implementation of QPSK for Wireless Modem has been proposed. QPSK modulation has various applications particularly in the design of wireless modem, cellular CDMA communication.
