Wireless Sensor Networks (WSNs) consist of tens or hundreds of small, inexpensive computers equipped with sensors and wireless communication capabilities. Because WSNs can be deployed without fixed infrastructure, they promise to enable sensing applications in environments where installing such infrastructure is not feasible. However, the lack of fixed infrastructure also presents a key challenge for application developers: sensor nodes must often operate for months or years at a time from fixed or limited energy sources. The focus of this dissertation is on reusable power management techniques designed to facilitate sensor network developers in achieving their systems' required lifetimes. Broadly speaking, power management techniques fall into two categories. Many power management protocols developed within the WSN community target specific hardware subsystems in isolation, such as sensor or radio hardware. The first part of this dissertation describes the Adaptive and Robust Topology control protocol (ART), a representative hardware-specific technique for conserving energy used by packet transmissions. In addition to these single-subsystem approaches, many applications can benefit greatly from holistic power management techniques that jointly consider the sensing, computation, and communication costs of potential application configurations. The second part of this dissertation extends this holistic power management approach to two families of structural health monitoring applications. By applying a partially-decentralized architecture, the cost of collecting vibration data for analysis at a centralized base station is greatly reduced. Finally, the last part of this dissertation discusses work toward a system for clinical early warning and intervention. The feasibility of this approach is demonstrated through preliminary study of an early warning component based on historical clinical data. An ongoing clinical trial of a real-time monitoring component also provides important guidelines for future clinical deployments based on WSNs.

Energy Management in Wireless Sensor Networks discusses this unavoidable issue in the application of Wireless Sensor Networks (WSN). To guarantee efficiency and durability in a network, the science must go beyond hardware solutions and seek alternative software solutions that allow for better data control from the source to delivery. Data transfer must obey different routing protocols, depending on the application type and network architecture. The correct protocol should allow for fluid information flow, as well as optimizing power consumption and resources – a challenge faced by dense networks. The topics covered in this book provide answers to these needs by introducing and exploring computer-based tools and protocol strategies for low power consumption and the implementation of routing mechanisms which include several levels of intervention, ranging from deployment to network operation. Explores ways to manage energy consumption during the design and implementation of WSN Helps users implement an increase in network longevity Presents intrinsic characteristics of wireless sensor networks

Doctoral Thesis / Dissertation from the year 2017 in the subject Electrotechnology, grade: PhD, , course: Doctor of Philosophy, language: English, abstract: Wireless Sensor Networks (WSNs) is fast emerging as prominent study area that attracting considerable research attention globally. The field has seen tremendous development in design and development of application related interfaces with sensor networks. Sensor network finds applications in several domains such as medical, military, home networks, space and so on. Many researchers strongly believe that WSNs can become as important as the internet in the near future. Just as the internet allows access to digital information anywhere, WSNs could easily provide remote interaction with the physical world. It is going to be the backbone of Ubiquitous Computing (UBICOMP).Through local collaboration among sensors, elimination of duplicate data, participation of relevant nodes in the given task etc. can produce a significant difference in energy conservation, thereby increasing the life time of the sensor network. As the number of nodes increases, data security becomes the most challenging part of the network. The intruders can hack the data any time during processing, transmission or at the receiver end. So, as a popular approach data encryption is the most commendable approach in today’s network. Asymmetric key encryption consumes more energy in processing and so not recommended for WSNs. Symmetric key encryption gives better performance with respect to asymmetric key encryption in WSN applications. It uses less computational power due to relatively effortless mathematical operations, and eventually spends less power. This thesis also proposes a symmetric data encryption through Tabulation method of Boolean function reductionfor the WSNs for secure data transmission. It also suggests a new secure approach, SEEMd, Security Enabled Energy Efficient Middleware algorithmfor the critical data sensing and gives a second chance to the nodes before it falls into to sleep mode for energy management. WSNs are designed for applications which range from small-size healthcare surveillance systems to large-scale agricultural monitoring or environmental monitoring. Thus, any WSN deployment, data aggregation, processing and communication have to assure minimum Quality of Service (QoS) in the network from application to application. In this circumstances, the proposed algorithms in this thesis proved to be efficient and reliable in energy saving and life time enhancement.

Numerous national studies and working groups have identified low-cost, very low-power wireless sensors and networks as a critical enabling technology for increasing energy efficiency, reducing waste, and optimizing processes. Research areas for developing such sensor and network platforms include microsensor arrays, ultra-low power electronics and signal conditioning, data/control transceivers, and robust wireless networks. A review of some of the research in the following areas will be discussed: (1) Low-cost, flexible multi-sensor array platforms (CO{sub 2}, NO{sub x}, CO, humidity, NH{sub 3}, O{sub 2}, occupancy, etc.) that enable energy and emission reductions in applications such as buildings and manufacturing; (2) Modeling investments (energy usage and savings to drive capital investment decisions) and estimated uptime improvements through pervasive gathering of equipment and process health data and its effects on energy; (3) Robust, self-configuring wireless sensor networks for energy management; and (4) Quality-of-service for secure and reliable data transmission from widely distributed sensors. Wireless communications is poised to support technical innovations in the industrial community, with widespread use of wireless sensors forecasted to improve manufacturing production and energy efficiency and reduce emissions. Progress being made in wireless system components, as described in this paper, is helping bring these projected improvements to reality.

Abstract: Wireless sensor networks (SNets) is a cost-efficient technology that is typically comprised of many low-power, low-cost sensors. Current and potential applications of SNets include tracking, automation, control, surveillance, reconnaissance, security, and monitoring. All of these applications require some form of intelligent signal processing and decision making algorithms. Proposed algorithms involving fusion-center-based architectures do not scale well with increasing number of sensors. Instead, scalable, robust and power-efficient distributed signal processing and decision making algorithms are required in order to realize the full potential of SNets. Therefore, in this thesis, we propose and analyze power-efficient in-network signal processing and decision making algorithms for applications that are modeled as distributed classification, data aggregation and symmetric function computation problems. The work in this thesis is a step towards solving distributed signal processing and decision making problems in low-power distributed sensor networks in a cost-efficient manner. The low-power, constrained communication architecture of emerging sensor network technologies demand scalable, asynchronous, energy-efficient and robust sensor network architectures and algorithms. We address these concerns in this thesis by declaring the proposed algorithm as: (i) Scalable because communication is restricted to immediate one-hop neighbors. (ii) Asynchronous because no synchronization between sensor nodes or order of transmission of messages are required. (iii) Energy-efficient in terms of reduced total power and average power consumed. (iv) Robust to node and edge failures. In this thesis we propose our solution in two main categories. (i) We propose and analyze pair-wise message passing algorithms, where sensors achieve the optimal classification performance. (ii) We propose and analyze algorithms in order to calculate the measurement statistics of certain functions. Under both these problems and proposed solutions, we assume each sensor initially has immediate access only to its observation, each communication takes place between sensor and its immediate neighbors, communication is not reliable, and node and edge failures occur. The proposed distributed classification algorithm is inspired by Belief Propagation algorithm. Our contributions include the calculation of convergence time and energy expenditure of the algorithm for certain sensor network topologies. The distributed function computation algorithm is inspired by coalescing random walks. We prove the convergence time and message count of the algorithms for certain sensor network topologies. We also present detailed comparisons of the proposed function computation algorithm with existing gossip spreading algorithms. In the last part of our work, we generalize the studied communication strategies in order to achieve reduced power consumption. By introducing power-control to the sensor network, we seek for trade-offs between average power consumed and total convergence time. Finally, we show how our work can be applied to realistic sensor network scenarios.
