Abstract

MATLAB® is a very popular high-level language and interactive environment used by millions of engineers and scientists worldwide. It lets you explore and visualize ideas and collaborate across disciplines ranging from signal and image processing, communications, and control systems, to computational finance.

In this session, Dr. Brett Shoelson from MathWorks will introduce the use of MATLAB for optimization, image processing and geospatial analysis. Using examples relevant to cell-tower positioning, and to the analysis and use of cell-tower data, they will discuss problem-solving approaches and workflows for solving complex optimization challenges. This discussion will include interactivity with web map services, data annotation and analysis, and optimization to maximize an objective function. Additionally, they will briefly discuss approaches to segmenting, classifying and quantifying regions in images, using color or other information.

Abstract:

Multiphysics RF Modeling and simulation tools are important part of RF system development and design verification. Multiphysics RF Modeling and simulation tools are used by designers of RF and microwave devices to design antennas, waveguides, filters, circuits, cavities, and metamaterials. By quickly and accurately simulating electromagnetic wave propagation and resonant behavior, engineers are able to compute electromagnetic field distributions, transmission, reflection, impedance, Q-factors, S-parameters, and power dissipation. Simulation offers you the benefits of lower cost combined with the ability to evaluate and predict physical effects that are not directly measurable in experiments. Compared to traditional electromagnetic modeling, you can also extend your model to include effects such as temperature rise, structural deformations, and fluid flow. Multiple physical effects can be coupled together and consequently affect all included physics during the simulation of an electromagnetic device.
In this presentation, Mr. Munn and Dr. Kalavagunta will introduce the core COMSOL Multiphysics and the RF module simulation tool. They will also provide an overview of the tool LiveLink for MATLAB simulation tools.

Agenda:
11:15am – 11:30am Registration
11:30am – 12:00pm Introduction to COMSOL Multiphysics
12:00pm – 1:00pm Emerging RF Technologies through Multiphysics Simulation

Backhauling in TV White Spaces by Dr. Narayan B. Mandayam, Ph.D

You are welcome to attend the COMSOC Distinguished Lecture "Backhauling in TV White Spaces" presented by Dr. Narayan B. Mandayam, Ph.D.  The presentation will commence at 11 AM on Saturday, May 18, 2013 in the Pioneer Room of the National Electronics Museum located at 1745 West Nursery Road Linthicum Heights, Maryland. Register online at https://meetings.vtools.ieee.org/meeting_view/list_meeting/18457 or RSVP Poitier Wright at PWright@IEEE.org.

Abstract:
The FCC’s opening up of TV white spaces for unlicensed use, has led to innovations in cognitive radio technology, spectrum sensing as well as novel proposals for dynamic spectrum access. Over a good part of the last decade, there has been a tremendous amount research on the theory and practice of cognitive radio networks such as dynamic spectrum access algorithms, networking protocols and software radio platform development.  There have also been efforts in the direction of advocating new spectrum governance and policy including models based on spectrum property rights, open access and hybrid versions that include a mix of the previous two approaches. While recent and prospective policy reforms and the wealth of wireless innovations hold great promise for realizing our national goals of achieving ubiquitous broadband and continued growth in our wireless sector and services, a significant barrier to entry is the lack of appropriate wireless backhaul solutions. Realizing the goal of ubiquitous wireless broadband, especially in rural areas represents the next major challenge for information technology that is increasingly dependent on mobile and wireless access.

Title:  Opportunistic Spectrum Access in Wireless Networks

Abstract:

In an opportunistic or dynamic spectrum access paradigm, devices sense the wireless environment for pockets of unused spectrum and dynamically tune their transmission and reception parameters to make efficient use of such spectrum holes.  The devices, generally known as cognitive radios, are said to be spectrum-agile and have the potential to recapture a significant portion of the idle spectrum. Spectrum holes arise in large part because of static spectrum allocation policies and may be characterized in terms of spatial, temporal, and frequential parameters.   

Opportunistic spectrum access seeks to increase spectrum utilization and overall network throughput without causing harmful interference to the primary users of the spectrum.  To achieve this, effective schemes for spectrum sensing and handoff of spectrum resources are needed.  In this talk, we provide an overview of the state-of-the-art in cognitive radio and opportunistic spectrum access technologies.  We also discuss some of our recent research activities related to the design and analysis of architectures and protocols for opportunistic spectrum access in wireless networks.

Abstract:

Dr.  Zhang presents a high level overview on the recent development of the cognitive radios/dynamical spectrum access (DSA) techniques, focusing on the following areas: standards activities in cognitive networks, characteristics of the available bandwidth of the primary users, sensing technologies and sensing intervals to detect white spaces, spectrum allocation schemes (graph coloring, game theory, machine learning), tradeoff between spectrum/performance gain versus additional overhead used in implementing DSA.  Some of tradeoff studies are presented in terms of price of anarchy, which is defined as the price that a decentralized system should pay for not being coordinated. We will also present a brief overview of the security issues associated with DSA networks, including communications, jamming/attacks and anti-jamming, and current projects related to DSA.

Abstract:

Cooperative communication is becoming a promising technology to increase the channel capacity of wireless networks.  The assignment of relay nodes to users plays a critical role to the resulting channel capacity.  A significant challenge is how to make the assignment scheme robust to selfish and cheating behavior of users while guaranteeing the social optimal system capacity.

In this talk, Dr. Xue will present an integrated optimal relay assignment scheme for cooperative networks.  To avoid system performance degradation due to selfish relay selections by the users, he proposes a payment mechanism for charging the users to induce them to converge to the optimal assignment.  To prevent relay nodes from manipulating the relay assignment by reporting transmission powers untruthfully, he proposes a payment mechanism to pay them for providing relaying service.
