Waltenegus Dargie Principles and Applications of Ubiquitous Sensing


Applications which use wireless sensors are increasing in number. The emergence of wireless sensor networks has also motivated the integration of a large number of small and lightweight nodes which integrate sensors, processors, and wireless transceivers. Existing books on wireless sensor networks mainly focus on protocols and networks and pay little attention to the sensors themselves which the author believes is the main focus. Without adequate knowledge of sensors as well as how they can be designed, realized and used, books on wireless sensor networks become too theoretical and irrelevant. The purpose of this book is to intimately acquaint readers with the technique of sensing (resistive, capacitive, inductive, magnetic, inertial, etc.) and existing sensor technologies. It also discusses how the sensors are used in a wide application domain and how new sensors can be designed and used in a novel way.

Muhammad Ahmed Khalid, Michael Chai Optimisation of AODV for Wireless Sensor Networks


Deployment of wireless sensor networks is rapidly increasing day by day to monitor physical environments for critical everyday applications. The main challenge for wireless sensor networks is establishing a reliable and fault tolerant communication channel and able to respond quickly and efficiently to the base station. Usually large numbers of micro sensors are deployed and replacing the battery in many cases is not an option thus long system lifetimes are required. Standalone measures such as choosing low power micro sensors are not alone sufficient to achieve energy efficiency, also applications have various limitations depending upon their architecture which makes it further more exigent to design networks without degrading the performance. This book focuses on identifying the performance challenges based on the statistical data obtained by analysing traffic trends in OPNET Simulator and proposes an enhanced RREP packet for AODV to improve its performance.

Joana Diekmann Coupling of Capillary Electrophoresis with Nuclear Magnetic Resonance Spectroscopy for the Analysis Pharmaceutical and Environmental Relevant Compounds


Master's Thesis from the year 2009 in the subject Chemistry - Analytical Chemistry, grade: 1,0, University of Hannover (Anorganische Chemie), language: English, abstract: Separation and identification of mass-limited chemical samples is the key to understand the complex nature of pharmaceutical and environmental systems. High efficiency separation techniques, such as capillary electrophoresis (CE), coupled to a non-destructive, information-rich detection, such as nuclear magnetic resonance (NMR) spectroscopy, have revolutionized the ability to separate and identify components in small sample volumes. Using this hyphenated system, structure elucidation of analytes separated during an electrophoretic process can be performed using NMR as an on-line detector. Although sensitivity remains an issue for on-line NMR detection, capillary NMR spectroscopy using microcoils has emerged as a major breakthrough for increasing the mass-sensitivity of NMR spectroscopy, because the limit of detection is proportional to the coil diameter. A further development is the miniaturization of the magnet enabling the possibility of a truly portable NMR system. This portable, low-cost NMR sensor, coupled to the rapid CE separation system could enable high-throughput and on-site identification of nanoliter amounts of solution. Furthermore, CE can provide on-line pre-concentration via electrokinetic injection or other stacking techniques to increase the sample concentration.In this research, couplin...

Sabit Ekin, Aly I. RF-Based Location Determination In Heterogeneous Sensor Networks


Today, wireless sensor networks have become a key technology for different types of "smart environments", and an intensive research effort is currently under way to enable the application of wireless sensor networks for a wide range of industrial problems. The need for a cost-effective means for sensor localization eliminates a variety of options including GPS. Several approaches are available to determine the location of the sensor nodes. Most of these algorithms require extra hardware resulting in higher costs that is not feasible for large networks. In this book, an RF-based localization approach is presented that utilizes particle filters. Due to the availability cheap wireless transmitters with received signal strength indicators, the proposed approach provides an effective solution to the challenging problem of localization. A prediction algorithm is designed to overcome the complications caused by fast fluctuations in the received signal power due to the propagation channel. Particle filters are then utilized to estimate the position of the sensors. A major development that has been presented in this book leads to significant increase in the positioning accuracy.

Gonizzi Pietro Low-power Distributed Data Storage in Wireless Sensor Networks


Sensor networks are a promising approach and a multi-disciplinary venture that combines computer networks, signal processing, software engineering, embedded systems, and statistics on the technology side. On the scientific applications side, they cover a large spectrum: safety and security of buildings or spaces, measuring traffic flows, environmental engineering, and ecology, to cite a few. Sensor networks also play an essential role in the era of the Internet of Things, as our personal mobile devices interact with sensor networks dispatched in the environment. Unfortunately, experimentation of sensor networks quickly becomes a nightmare if the number of nodes to be installed exceeds a few dozens. SensLAB is a very large scale open wireless sensor network testbed, which deploys 1024 nodes over 4 interconnected sites and offers a reference tool for the wireless sensor network community. This book gives a comprehensive description of the Senslab platform through two relevant topics. The first topic covers IP connectivity in low-power smart objects and Internet of Things. The second topic covers distributed data storage techniques to reduce packet loss and energy consumption.

Nathan Gomes J. Next Generation Wireless Communications Using Radio over Fiber


Taking a coherent and logical approach, this book describes the potential use of co-ordinated multipoint systems supported by radio over fiber. It covers an impressive breadth of topics, ranging from components, subsystem and system architecture, to network management and business perspectives. The authors show the importance of radio over fiber in eliminating or mitigating against the current, perceived barriers to the use of co-ordinated multipoint, and the drivers for standardisation activities in future mobile/wireless systems over the next few years. The book brings together the system concept for centralized processing, including what is required for co-existence with legacy wireless systems, the algorithms that can be used for improving wireless bandwidth utilization at physical and MAC layers and the radio over fiber network and link design necessary to support the wireless system. Other important research is also covered as the authors look at compensating for radio over fiber impairments and providing simple network management functions. A study of service provision and the business case for such a future wireless system is also fully considered. This book comes at an important time for future wireless systems with standardization of fourth generation wireless systems still ongoing. The content enables readers to make key decisions about future standardisation and their own research work. The business analysis also makes the book useful to those involved in deciding the future directions of telecoms organisations. This information will be core to their decision-making as it provides technical knowledge of the state-of-the-art but also system level assessments of what is possible in a business environment.

Manik Gupta Security Model Beyond Energy Dependency in Wireless Sensor Networks


Sensor Nodes in Military Applications always suffer constraints over energy due to their small size & when we want to apply hard security algorithms we need to consider the energy factors as well because security and energy always behave in inverse proportions. In this book, we have presented a security model independent of energy (SMIE) for Wireless Sensor Networks designed with actual availability of never lasting energy within the network rather than any assumption. This model provides ample amount of energy supplied wirelessly to the Base Station as well as to the sensor nodes in the deployment area, besides a new key management technique that overcomes the drawback of all existing strong keying techniques is proposed at a very reasonable cost. The solution is designed keeping in mind the deployment of sensor nodes in isolated environment as well as in military applications, where human interference is low but surveillance is at high priority. The book considers Base Station as flying object like UAV and provides solution to the challenges which it can face in such type of scenario. The book will open a number of new research aspects in the field of Wireless Sensor Networks.

Saeed Ur Rehman Wireless Sensor Network


The emerging wireless technologies target a comprehensive range of new applications that the legacy wireless networks cannot support. On the contrary, low rate, low power data collection applications have been anticipated to have a crucial impact on our understanding of the physical world. Simplified technological versions of wireless networks are being worked upon to support these low rate applications in order to meet the stringent requirements of low energy consumption. In wireless networks, Medium Access Control (MAC) sublayer plays a vital role in satisfying the requirement of varying Quality of Service (QoS). Many MAC solutions have been proposed for these networks. In this book, the feasibility of existing solutions for MAC sublayer are reviewed and analyzed for Wireless Sensor Networks. Then the analysis of MAC protocol for recently emerged low rate, low power IEEE 802.15.4 standard is presented. The impact of packet size and number of nodes on the throughput, success probability and average delay is analyzed with Markov chain and OPNET simulation.

Anand Nayyar Improvised Energy Efficient Routing Protocol based on Ant Colony Optimization (ACO) for Wireless Sensor Networks


Doctoral Thesis / Dissertation from the year 2017 in the subject Computer Science - Miscellaneous, , course: Ph.D Computer Science, language: English, abstract: Routing and Energy Efficiency is regarded as highly challenging area of Sensor networks. Significant advancements in Wireless Sensor Networks (WSNs) opens doors for wide implementation in real-time applications like Industrial Monitoring, Smart Cities development, Underwater monitoring operations, tracking objects and many more. Energy Efficient routing is regarded as the most challenging task. Sensor networks mostly operate in complex and dynamic environments and routing becomes tedious task to maintain as the network size increases. Lots of routing protocols- Reactive, Proactive and Hybrid are proposed by researchers but every protocol faces some limitations in terms of energy, routing, packet delivery ratio and security. Therefore, to overcome all the routing issues, the trend has shifted to Biological based Algorithms like Swarm Intelligence based techniques. Ant Colony Optimization based routing protocols have demonstrated exceptional results in terms of performance when applied to WSN routing. This thesis outlines routing protocols in sensor networks, highlight the concept of Swarm Intelligence and presents various Ant Colony Optimization based routing protocols for sensor networks. In addition to this, we present Ant Colony based Energy Efficient routing protocol (IEEMARP = Improvised Energy Efficient Multipath...
