SUMMARY:ECE PhD Proposal Review: Abhimanyu Venkatraman Sheshashayee
DESCRIPTION:PhD Proposal Review: Wake-up Radio-enabled Wireless Networking: Measurements and Evaluation of Data Collection Techniques in Static and Mobile Scenarios \nAbhimanyu Venkatraman Sheshashayee \nLocation: 432 ISEC \nAbstract: Multi-hop Wireless Networks such as Wireless Sensor Networks and similar networks that enable most applications of the Internet of Things\, are comprised of wirelessly communicating nodes that are powered by batteries. In many relevant scenarios\, it is inconvenient or impossible to replenish or replace the batteries of these nodes\, which limits the operational lifespan of the network. One of the most significant sources of power consumption comes from idle listening on the node’s main radio. This can be ameliorated by Wake-up Radio (WuR) technology: Nodes keep their main radio off while listening for a signal via an ultra-low-power auxiliary radio used only for wake-up purposes. When the appropriate signal is received\, the node turns its main radio on\, conducts the necessary exchange of packets\, and then turns off its main radio. This strategy allows for a considerable reduction in power consumption.\nThis dissertation studies data collection approaches that leverage WuR technology to maximize the lifespan of multi-hop networks for data gathering via routing and via a Mobile Data Collector (MDC). We analyze contemporary WuR technology\, isolating the main criticalities of the state-of-the-art\, including range and data rates. We use a prototype with highly desirable characteristics to conduct experiments to measure its effective communication range\, in both static and mobile scenarios. We then examine the application of WuR technology to data collection scenarios based on multi-hop routing. We devise new techniques and evaluate the effects of different WuR characteristics on the performance of routing\, considering for the first time what the network performance could be if we could overcome the limitation of current WuRs.\nThe remainder of the dissertation will focus on mobile data collection protocols and approaches. We are conducting a comprehensive survey of mobile data collection protocols. We plan to execute exhaustive simulation-based experiments with selected protocols applied to various scenarios. We will evaluate the performance of those protocols and determine how their features influence their performance. We will use the information gleaned from our investigations to develop a novel mobile data collection protocol that effectively utilizes WuR technology to maximize network lifespan. The effectiveness of our protocol will be evaluated using both simulations and physical experiments\, sporting an ad hoc testbed of WuR-enabled nodes and a quad-rotor drone for the MDC.

SUMMARY:ECE PhD Proposal Review: Stella Banou
DESCRIPTION:PhD Proposal Review: Coupling Methods for Wireless Intra-body Communication and Sensing \nStella Banou \nLocation: 432 ISEC \nAbstract: Advances in miniaturized bio-compatible Internet of Things (IoT) device design and wireless connectivity have resulted in rapid strides towards realizing the vision of connected health and ubiquitous monitoring of physiological conditions. Core enablers of this capability are wearable and implanted IoT devices\, albeit with limitations arising from their low energy storage and computational power. This thesis goes beyond the RF-only communication standards by exploring alternate communication modalities that are more amenable for inter- and intra-body communication. In summary\, this thesis explores the conductive and radiating nature of the human body as a channel for three non-RF coupling communication methods – Galvanic\, Magnetic and Capacitive coupling.\nIn part I\, an implementation of Galvanic Coupling-based beamforming is presented for implant to wearable communication. The key idea here is to exploit the conductivity of human tissue and transmit weak electrical signals by coupling them via electrodes to muscle tissue in a way that concentrates energy at the receiver location. In part II\, we focus on realizing a relay network of IoT devices for both implant-implant and implant to on-skin sensor communication using Magnetic Resonance Coupling. The advantage of this method over Galvanic Coupling is that the former reduces attenuation when signals pass through human tissue. In part III\, we enhance the scope of the connected health paradigm to now include sensing for proximity and for automated encouraging of healthy habits that mitigate the spread of communicable diseases using Capacitive Coupling.\nAs part of proposed work\, we will design a novel human antenna field to sense and communicate with other IoT devices in the near field – within 2.5 meters\, also using Capacitive Coupling. This will complete the full cycle of data flow\, from implanted to wearable devices and finally connect the body network to the computational cloud for the next generation of IoT-enabled healthcare.
