Available in PDF, EPUB and Kindle. Book excerpt: Recently, there has been an explosion in the growth of wirelessly connected devices. The number of autonomous devices is expected to reach trillions in total. Autonomous devices range from home thermostats to industrial sensors. To route communication from these devices to the end-user, a base station is required. Collectively, the base station and autonomous devices form a wireless sensor network. However, the proliferation of wireless sensor networks has led to an unprecedented energy management crisis on two fronts. First is energy generation, for which establishing methods of self-powering are critically important since battery replacement is infeasible for the trillions of autonomous devices. The second is efficient power use by the base station. Efficient power delivery to the RF power amplifier (PA) is imperative, which dissipates a majority of base station power. Motivated by these core challenges, this dissertation presents techniques for energy management and harvesting to achieve self-powered operation and envelope tracking techniques for optimized power delivery to the base station RF PA. First, a reconfigurable energy management unit (EMU) is introduced. The EMU achieves unification of an energy source, energy storage, voltage regulation, and energy recycling for dynamic voltage scaling by implementing multi-directional energy flow control. A reconfigurable switching converter architecture is implemented to accommodate flexible voltage conversion and multi-directional energy flow. Furthermore, supercapacitors are employed to enhance operation lifetime. Second, a piezoelectric vibration energy harvester is developed to achieve self-powered operation. However, significant challenges remain unresolved with regard to harvesting from time-varying vibrations. To overcome these challenges, an adaptive impedance matching technique is proposed. To retain reasonable efficiency at low power levels, the controller is designed with nanopower circuits. Last, a switching-converter-only envelope modulator is developed to achieve efficient power delivery to the base station PA. Conventionally, a linear regulator is required to attain fast tracking, but is a significant source of efficiency degradation. To eliminate the linear regulator, a dual-phase switching converter with synchronized adaptive voltage tracking (SAVT) control is employed. SAVT control enables synchronization and fast hysteretic response for voltage tracking. To overcome the switching converter slew rate limit, a push-pull slew rate enhancer is implemented.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, we develop and analyze effective energy management policies for wireless sensor networks in emerging applications. Existing methods in this area have primarily focused on energy conservation through the use of various communication techniques. However, in most applications of wireless sensor networks, savings in energy come at the expense of several performance parameters. Therefore it is necessary to manage energy consumption while being conscious of its effects on performance. In most cases, such energy-performance issues are specific to the nature of the application. Our research has been motivated by new techniques and applications where efficient energy-performance trade-off decisions are required. We primarily study the following trade-off cases: energy and node replacement costs (Case I), energy and delay (Case II), and energy and availability (Case III). We consider these trade-off situations separately in three distinct problem scenarios. In the first problem (Case I), we consider minimizing energy and node replacement costs in underwater wireless sensor networks for seismic monitoring application. In this case, we introduce mixed-integer programming (MIP) formulations based on a combined routing and node replacement policy approach and develop effective policies for large problem instances where our MIP models are intractable. In the second problem (Case II), we develop a Markov decision process (MDP) model to manage energy-delay trade-off in network coding which is a new energy-saving technique for wireless networks. Here we derive properties of the optimal policy and develop insights into other simple policies that are later shown to be efficient in particular situations. In the third problem (Case III), we consider an autonomous energy harvesting sensor network where nodes are turned off from time to time to operate in an "energy-neutral" manner. In this case, we use stochastic fluid-flow analysis to evaluate and analyze the availability of the sensor nodes under effective energy management policies. In each of the above problem cases, we develop analytical formulations, and derive and/or analyze policies that effectively manage the considered energy-performance trade-off. Overall, our analyses and solution methods make new contributions to both operations research and communication networking literature.

Download or read book Energy Aware System Design written by Chong-Min Kyung and published by Springer Science & Business Media. This book was released on 2011-06-17 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power consumption becomes the most important design goal in a wide range of electronic systems. There are two driving forces towards this trend: continuing device scaling and ever increasing demand of higher computing power. First, device scaling continues to satisfy Moore’s law via a conventional way of scaling (More Moore) and a new way of exploiting the vertical integration (More than Moore). Second, mobile and IT convergence requires more computing power on the silicon chip than ever. Cell phones are now evolving towards mobile PC. PCs and data centers are becoming commodities in house and a must in industry. Both supply enabled by device scaling and demand triggered by the convergence trend realize more computation on chip (via multi-core, integration of diverse functionalities on mobile SoCs, etc.) and finally more power consumption incurring power-related issues and constraints. Energy-Aware System Design: Algorithms and Architectures provides state-of-the-art ideas for low power design methods from circuit, architecture to software level and offers design case studies in three fast growing areas of mobile storage, biomedical and security. Important topics and features: - Describes very recent advanced issues and methods for energy-aware design at each design level from circuit and architecture to algorithm level, and also covering important blocks including low power main memory subsystem and on-chip network at architecture level - Explains efficient power conversion and delivery which is becoming important as heterogeneous power sources are adopted for digital and non-digital parts - Investigates 3D die stacking emphasizing temperature awareness for better perspective on energy efficiency - Presents three practical energy-aware design case studies; novel storage device (e.g., solid state disk), biomedical electronics (e.g., cochlear and retina implants), and wireless surveillance camera systems. Researchers and engineers in the field of hardware and software design will find this book an excellent starting point to catch up with the state-of-the-art ideas of low power design.
