On the area and energy scalability of wireless network-on-chip: a model-based benchmarked design space exploration
Networks-on-Chip (NoCs) are emerging as the way
to interconnect the processing cores and the memory within
a chip multiprocessor. As recent years have seen a significant
increase in the number of cores per chip, it is crucial to guarantee
the scalability of NoCs in order to avoid communication to
become the next performance bottleneck in multicore processors.
Among other alternatives, the concept of Wireless Network-on-
Chip (WNoC) has been proposed, wherein on-chip antennas
would provide native broadcast capabilities leading to enhanced
network performance. Since energy consumption and chip area
are the two primary constraints, this work is aimed to explore
the area and energy implications of scaling a WNoC in terms of
(a) the number of cores within the chip, and (b) the capacity of
each link in the network. To this end, an integral design space
exploration is performed, covering implementation aspects (area
and energy), communication aspects (link capacity) and networklevel
considerations (number of cores and network architecture).
The study is entirely based upon analytical models, which will
allow to benchmark the WNoC scalability against a baseline
NoC. Eventually, this investigation will provide qualitative and
quantitative guidelines for the design of future transceivers for
wireless on-chip communication.Peer ReviewedPostprint (author’s final draft
Nano-Communication for Biomedical Applications: A Review on the State-of-the-Art From Physical Layers to Novel Networking Concepts
We review EM modeling of the human body, which is essential for in vivo wireless communication channel characterization; discuss EM wave propagation through human tissues; present the choice of operational frequencies based on current standards and examine their effects on communication system performance; discuss the challenges of in vivo antenna design, as the antenna is generally considered to be an integral part of the in vivo channel; review the propagation models for the in vivo wireless communication channel and discuss the main differences relative to the ex vivo channel; and address several open research problems and future research directions
Intra-Body Communications for Nervous System Applications: Current Technologies and Future Directions
The Internet of Medical Things (IoMT) paradigm will enable next generation
healthcare by enhancing human abilities, supporting continuous body monitoring
and restoring lost physiological functions due to serious impairments. This
paper presents intra-body communication solutions that interconnect implantable
devices for application to the nervous system, challenging the specific
features of the complex intra-body scenario. The presented approaches include
both speculative and implementative methods, ranging from neural signal
transmission to testbeds, to be applied to specific neural diseases therapies.
Also future directions in this research area are considered to overcome the
existing technical challenges mainly associated with miniaturization, power
supply, and multi-scale communications.Comment: https://www.sciencedirect.com/science/article/pii/S138912862300163
The Boston University Photonics Center annual report 2016-2017
This repository item contains an annual report that summarizes activities of the Boston University Photonics Center in the 2016-2017 academic year. The report provides quantitative and descriptive information regarding photonics programs in education, interdisciplinary research, business innovation, and technology development. The Boston University Photonics Center (BUPC) is an interdisciplinary hub for education, research, scholarship, innovation, and technology development associated with practical uses of light.This has undoubtedly been the Photonics Center’s best year since I became Director 10 years ago. In the following pages, you will see highlights of the Center’s activities in the past year, including more than 100 notable scholarly publications in the leading journals in our field, and the attraction of more than 22 million dollars in new research grants/contracts. Last year I had the honor to lead an international search for the first recipient of the Moustakas Endowed Professorship in Optics and Photonics, in collaboration with ECE Department Chair Clem Karl. This professorship honors the Center’s most impactful scholar and one of the Center’s founding visionaries, Professor Theodore Moustakas. We are delighted to haveawarded this professorship to Professor Ji-Xin Cheng, who joined our faculty this year.The past year also marked the launch of Boston University’s Neurophotonics Center, which will be allied closely with the Photonics Center. Leading that Center will be a distinguished new faculty member, Professor David Boas. David and I are together leading a new Neurophotonics NSF Research Traineeship Program that will provide $3M to promote graduate traineeships in this emerging new field. We had a busy summer hosting NSF Sites for Research Experiences for Undergraduates, Research Experiences for Teachers, and the BU Student Satellite Program. As a community, we emphasized the theme of “Optics of Cancer Imaging” at our annual symposium, hosted by Darren Roblyer. We entered a five-year second phase of NSF funding in our Industry/University Collaborative Research Center on Biophotonic Sensors and Systems, which has become the centerpiece of our translational biophotonics program. That I/UCRC continues to focus on advancing the health care and medical device industries
