Power Optimization Of Solar Powered Standalone Wireless Sensor System, Rajan Amatya
Power Optimization Of Solar Powered Standalone Wireless Sensor System, Rajan Amatya
Masters Theses
Wireless sensor systems are common in applications where harsh environmental conditions or remote locations make it difficult to run wires. Having these sensor systems self-powered is essential as it is difficult for battery replacement. Using solar as an alternative source of energy can be a medium to charge the battery in such scenarios. With an increasing number of portable devices powered by battery; more and more research is focused on low-power design technique. For this thesis, a microcontroller (Texas Instruments MSP432) was used along with a digital sensor (Bosch BME280) to provide temperature, pressure and humidity information, and Wi-Fi module …

Bandwidth and computation-intensive Big Data applications in disciplines like social media, bio- and nano-informatics, Internet-of-Things (IoT), and real-time analytics, are pushing existing access and core (backbone) networks as well as Data Center Networks (DCNs) to their limits. Next generation DCNs must support continuously increasing network traffic while satisfying minimum performance requirements of latency, reliability, flexibility and scalability. Therefore, a larger number of cables (i.e., copper-cables and fiber optics) may be required in conventional wired DCNs. In addition to limiting the possible topologies, large number of cables may result into design and development problems related to wire ducting and maintenance, heat …

One of the most important Internet of Things applications is the wireless body sensor network (WBSN), which can provide universal health care, disease prevention, and control. Due to large deployments of small scale smart sensors in WBSNs, security, and privacy guarantees (e.g., security and safety-critical data, sensitive private information) are becoming a challenging issue because these sensor nodes communicate using an open channel, i.e., Internet. We implement data integrity (to resist against malicious tampering) using the secure hash algorithm 3 (SHA-3) when smart sensors in WBSNs communicate with each other using the Internet. Due to the limited resources (i.e., storage, …
Wireless Power And Data Transfer Using Inductively Resonant Coils, Seth C. Raymond
Wireless Power And Data Transfer Using Inductively Resonant Coils, Seth C. Raymond
Honors College
In electronics, resonance occurs when the admittances of circuit components, the imaginary parts of the component impedances, cancel each other out. Operation of circuits at their resonant frequencies can cause oscillation of signals at extreme levels. Nikola Tesla developed the concept of harnessing the capabilities of resonance by transmitting energy wirelessly between two inductively resonant coils. In 1897, his newly patented design, known as the Tesla coil, was an early prototype used to realize his theory. However, only in relatively recent history has the idea been expanded upon and used for commercial applications. Medical devices, such as pacemakers, are powered …
