Wireless sensor network is mainly used for real time applications which raise fundamental problems. These problems are like limited energy resources and replacement task. Therefore good functioning of such networks depends on energies of nodes. In this paper we have introduced analytical model which predict the energy consumption. We have also compared two different formats of nodes which are organized as cluster based and grid based. We have used new existing tool for simulation analysis QualNet.

This paper presents an innovative design and accurate approach to the measurement of flow rate for moderate flow applications. It also deduces linear relationship between flow rate and the change in resistance of the bend sensor used in the setup. The sensor apparatus is very simple to calibrate and install which is a fixed beam cantilever system with one moving end which would give a digital output. The displacement values of free end of the sensor are analysed using ANSYS Finite Element Analysis software.

The peculiar features of Wireless sensor Networks (WSNs) suggest to exploit the distributed computing paradigm to perform complex tasks in a collaborative manner, in order to overcome the constraints related to sensor nodes limited capabilities. In this context, we describe a lightweight middleware platform to support the development of distributed applications on WSNs. The platform provides just a minimal general-purpose software layer, while the application components, including communication and processing algorithms, as well as the exchanged data, are described symbolically, with neither preformed syntax nor strict distinction between data and code. Our approach allows for interactive development of applications on each node, and requires no cross-compilation, a common practice that makes the development of WSN applications rigid and time-consuming. This way, tasks and behavior of each node can be modified at runtime, even after the network deployment, by sending the node executable code. (C) 2014 Published by Elsevier B.V.

Because malicious nodes always drop packets deliberately, send redundant packets arbitrarily and modify packets illegally, Ad hoc networks are prone to be threatened by interior attacks. Through the analysis of these malicious behaviours, a trust evaluation model based on Linux Net-filter frame is proposed, which could monitor the illegal operations and evaluate the trust value of nodes, the Trust Dynamic Source Route protocol is implemented finally by this approach, which could improve the performance of the network. The performance of the improved DSR is analyzed and compared with the traditional DSR. Simulation results show the improved protocol can identify dangerous sensor nodes effectively and improves the quality and success ratio of tasks.

international conference on VLSI Design

The microfabrication technology has had a chequered history of over 50 years in the field of microelectronics. Aggressive miniaturization of microelectronic devices has resulted in faster logic circuits and it has also reduced their power requirements. MOSFET device dimensions have already entered the sub-100 nanometer regime. The same principles of microfabrication were applied to make miniaturized 3-dimensional mechanical structures. This helped in the advent of micro electro-mechanical systems or MEMS. Initially, i.e. in early nineties, the MEMS field was dominated by mechanical applications. However, now MEMS refers to all miniaturized systems including silicon based mechanical drivers, chemical and biological sensors and actuators, and miniature devices made from plastics or ceramics. The half-day tutorial would begin with a synoptic overview of the area, highlight some of the challenges and outline the scope of the tutorial. It would be followed with an introduction to the design of microsensors, such as the pressure sensor and the accelerometer that began the MEMS revolution. Micromachined Electro-Mechanical Systems (MEMS), also called Microfabricated Systems (MS), have evoked great interest in the scientific and engineering communities. This is primarily due to several substantive advantages that MEMS offer: orders of magnitude smaller size, better performance than other solutions, possibilities for batch fabrication and cost-effective integration with electronics, virtually zero dc power consumption and potentially large reduction in power consumption, etc. The application domains cover microsensors and actuators for physical quantities (MEMS), of which MEMS for automobile & consumer electronics forms a large segment; microfabricated subsystems for communications and computer systems (RF-MEMS & MOMS); and microfabricated systems for chemical assay (microTAS) and for biochemical and biomedical assay (bioMEMS and DNA chips).

Wireless communication and sensor networks would form the backbone to create pervasive and ubiquitous environments that would have profound influence on the society and thus are important to the society. The wireless communication technologies and wireless sensor networks would encompass a wide range of domains such as HW devices such as motes, sensors and associated instrumentation, actuators, transmitters, receivers, antennas, etc., sensor network aspects such as topologies, routing algorithms, integration of heterogeneous network elements and topologies, designing RF devices and systems for energy efficiency and reliability etc. These sensor networks would provide opportunity to continuously and in a distributed manner monitor the environment and generate the necessary warnings and actions. However most of the developments have been demonstrated only in controlled and laboratory environments. So we are yet to see those powerful, ubiquitous applications for the benefit of the society. The conference and consequentially the proceedings would provide opportunity to the researchers to interact with other researchers and share their researches covering all the above areas. The proceedings of the conference thus covers the research work of different authors in the area of wireless sensor networks, wireless communications, devices, tools and techniques for WSN, and applications of wireless sensor *** book is beneficial for those researchers who are working in the area of wireless sensor networks, wireless communication, and developing applications of Wireless sensor networks.

Conventional cryptography methods alone are not adequate for secure routing in Wireless sensor Networks (WSNs). These networks are more vulnerable to security attacks due to their diverse applications, lack of supervision and limitations in view of resource, processing and storage. To mitigate these problems, trust is widely used as a tool to provide better security by aiding routing protocols. In recent years, numerous researchers have proposed wide variety of solutions based on trust. However, all these solutions carry their own design. In this paper, we attempt to present steps for a systematic design of trust management systems for WSNs. In addition, we address the techniques followed by scholars in implementing trust frameworks. Furthermore, we provide discussion on state-of-the-art research in designing trust systems with summary and comparisons.

Augmenting women’s safety-in-numbers in railway carriages with wireless sensor networks

Sexual harassment of women traveling on railway carriages is a widespread problem. The predominant method used to address this problem is for women to travel in groups, utilizing Safety-in-Numbers, to hinder and discourage attacks against them. However, when the number of women in a railway carriage is low, there is no safety system in place to detect the imminent danger and proactively alert security personnel. In this work, we consider a system that keeps track of the number of passengers in a railway carriage using a wireless sensor network and automatically notifies security personnel when the number of passengers goes below a certain threshold. Here, we consider different scenarios and evaluate if our solution approach will work in the different cases considered. We also evaluated different techniques for automatically counting the number of people aboard a railway carriage. Our initial experimental results show that we are able to estimate the number of people in a room (considered in lieu of a railway carriage) with a high degree of accuracy using the background subtraction method. We hope that the proposed architecture in concert with the people counting technique will be able to significantly improve the safety of women traveling in railway carriages. © Springer India 2016.

Honey bees have held a critical role in agriculture and nutrition from the dawn of human civilisation. The most crucial role of the bee is pollination; the value of pollination dependant crops is estimated at € 155 billion per year with honey bees identified as the most important pollinator insect. It is clear that honey bees are a vitally important part of the environment which cannot be allowed to fall into decline. The project outlined in this paper uses Wireless sensor Network (WSN) technology to monitor a beehive colony and collect key information about activity/environment within a beehive as well as its surrounding area. This project uses low power WSN technologies, including novel sensing techniques, energy neutral operation, and multi-radio communications; together with cloud computing to monitor the behaviour within a beehive. The insights gained through this activity could reduce long term costs and improve the yield of beekeeping, as well as providing new scientific evidence for a range of honey bee health issues. WSN is an emerging modern technology, key to the novel concept of the Internet of Things (IoT). Comprised of embedded sensing, computing and wireless communication devices, they have found applications in nearly every aspect of daily life. Informed by biologists' hypotheses, this work used existing, commercially available WSN platforms together with custom built systems in an innovative application to monitor honey bee health and activity in order to better understand how to remotly monitor the health and behaviour of the bees. Heterogeneous sensors were deployed, monitoring the honey bees in the hive (temperature, CO2, pollutants etc.). Weather conditions throughout the deployment were recorded and a relationship between the hive conditions and external conditions was observed. A full solution is presented including a smart hive, communication, and data aggregation and visualisation tools. Future work will focus on improving the energy perform

sensors are battery powered devices which are attracting a tremendous attention owing to their wide range of applications. To overcome their intrinsic power limitations, reducing energy consumption in wireless sensor networks (WSNs) is a critical issue to expand their lifespan. Balancing nodes' activities and duty cycling are efficient ways that could enhance WSN's performances. Yet, most existing works only rely on these mechanisms to optimize energy consumption at MAC layer without taking into account the upper layers overhead. In this paper, we introduce a new power saving mechanism for wireless sensor networks that achieves cross-layer functioning to provide an adaptive duty cycle and a minimum routing overhead. This mechanism relies on two basic functions: an asynchronous duty cycling for nodes' activity balancing and a lightweight geographic routing. We show through several simulations that our proposed approach outperforms existing works in terms of residual energy, energy consumption balancing and packets delivery ratio.
