APPLICATION OF COMPRESSED SENSING THEORY TO RADAR SIGNAL PROCESSING: TUTORIAL AND RECENT DEVELOPMENTS

 

Date:  Thursday July 11th, 2019.

Location: Royal Military College of Canada, Kingston, Room S4214

Speaker:  Dr. Soheil Salari

 

Abstract

During the last decade, the emerging technique of compressed sensing has become a popular subject in signal processing and sensor systems since it can reduce the sampling rate and computational complexity of practical systems without performance loss. The technique of compressed sensing has been successfully applied in signal acquisition, image compression, and data reduction. Based on compressed sensing theory, the original radar echo can be sampled at a lower rate, and then the detection and imaging can be implemented. Although the theory of compressed sensing has been investigated for some radar and localization problems, several important questions have not been answered yet. This presentation introduces the main principle of compressed sensing theory, and then reviews some recent developments in the application of the compressed sensing theory to radar signal processing.

The Joint Communications & Computer Chapter of IEEE Kingston Section is proud to present the following IEEE distinguished lecture:

 

SECURITY IN SDN/NFV AND 5G NETWORKS – OPPORTUNITIES AND CHALLENGES

&

MOBILITY HANDOVER OPTIMIZATION FRAMEWORK AND IEEE 5G INITIATIVE

 

 

Date:  Tuesday April. 2nd, 2019.

Time:  10:30 AM

Location: Queens University, Walter Light Hall, Room 302

Speaker:  Dr. Ashutosh Dutta

 

Talk 1: Security in SDN/NFV and 5G Networks-Opportunities and Challenges – 30 minutes

Software Defined Networking (SDN) and Network Function Virtualization (NFV) are the key pillars of future networks, including 5G and Beyond that promise to support emerging applications such as enhanced mobile broadband, ultra low latency, massive sensing type applications while providing the resiliency in the network. Service providers and other verticals (e.g., Connected Cars, IOT, eHealth) can leverage SDN/NFV to provide flexible and cost-effective service without compromising the end user quality of service (QoS). While NFV and SDN open up the door for flexible networks and rapid service creation, these offer both security opportunities while also introducing additional challenges and complexities, in some cases. With the rapid proliferation of 4G and 5G networks, operators have now started the trial deployment of network function virtualization, especially with the introduction of various virtualized network elements in the access and core networks. These include elements such as virtualized Evolved Packet Core (vEPC), virtualized IP Multimedia Services (vIMS), Virtualized Residential Gateway, and Virtualized Next Generation Firewalls. However, very little attention has been given to the security aspects of virtualization. While several standardization bodies (e.g., ETSI, 3GPP, NGMN, ATIS, TIA) have started looking into the many security issues introduced by SDN/NFV, additional work is needed with larger security community involvement including vendors, operators, universities, and regulators. This tutorial will address evolution of cellular technologies towards 5G but will largely focus on various security challenges and opportunities introduced by SDN/NFV and 5G networks such as Hypervisor, Virtual Network Functions (VNFs), SDN Controller, Orchestrator, Network slicing, Cloud RAN, and security function virtualization. This tutorial will also highlight some of the ongoing activities within various standards communities and will illustrate a few deployment use case scenarios for security including threat taxonomy for both operator and enterprise networks. In addition, I will also describe some of the ongoing activities within IEEE Future Network initiative including roadmap efforts and various ways one can get involved and contribute to this initiative.

 

Talk 2: Mobility Handover Optimization Framework and IEEE 5G Initiative – 30 minutes

As mobile networks continue to grow and converge with the Internet, new wireless devices and their use are outnumbering the use of fixed network. Mobility management needs to meet the requirements of existing and emerging network technologies and applications. It may be supported in different layers of the network protocol stack. At the IP layer, Mobile IP, an IP-based mobility management, has the advantage of being applicable in any IP-based network, but is faced with many deployment challenges. Numerous variants of Mobile IP have been proposed to address these challenges in different network environments. Research in mobility management has become more active, especially with the mobile networks continuing to evolve from hierarchical towards more flattened network and densification of wireless networks. This talk presents the basics, recent advances, and future directions for mobility protocols at various layers (e.g., network, transport and application). This talk then provides taxonomy of existing mobility protocols, illustrates an abstract mobility model that can be used to support various handoff scenarios. Various handoff optimization methodologies will be explained supported by experimental and simulation results. This talk cites a few deployment scenarios to describe applicability of mobility protocols to various network environments. Finally, the talk goes through the best practices for mobility management and provides some research directions.

Integrated Terrestrial/Aerial 6G Networks for Ubiquitous 3D Super-Connectivity in 2030s

Monday, November 5th, 2018

The Joint Communications & Computer Chapter of IEEE Kingston Section is proud to present the following IEEE distinguished lecture:

 

INTEGRATED TERRESTRIAL/AERIAL 6G NETWORKS FOR UBIQUITOUS 3D SUPER-CONNECTIVITY IN 2030s

 

 

Date:  Tuesday Nov. 13th, 2018.

Time:  2:00 – 3:00 PM

Location: Queens University, Walter Light Hall, Room 302

Speaker:  Professor Halim Yanikomeroglu

Abstract:  As the 5G standards are currently being developed with a scheduled completion date of late-2019, it is time to reinitiate a brainstorming endeavour followed by the technical groundwork towards the subsequent generation (6G) wireless networks of 2030s.

One reasonable starting point in this new 6G discussion is to reflect on the possible shortcomings of the 5G networks to-be-deployed. 5G promises to provide connectivity for a broad range of use-cases in a variety of vertical industries; after all, this rich set of scenarios is indeed what distinguishes 5G from the previous four generations. Many of the envisioned 5G use-cases require challenging target values for one or more of the key QoS elements, such as high rate, high reliability, low latency, and high energy efficiency; we refer to the presence of such demanding links as the super-connectivity.

However, the very fundamental principles of digital and wireless communications reveal that the provision of ubiquitous super-connectivity in the global scale – i.e., beyond indoors, dense downtown or campus-type areas – is infeasible with the legacy terrestrial network architecture as this would require prohibitively expensive gross over-provisioning. The problem will only exacerbate with even more demanding 6G use-cases such as UAVs requiring connectivity (ex: delivery drones), thus the need for 3D super-connectivity.

In this talk, we will present a 5-layer vertical architecture composed of fully integrated terrestrial and aerial layers for 6G networks of 2030s:

  • Terrestrial HetNets with macro-, micro-, and pico-BSs
  • Flying-BSs (aerial-/UAV-/drone-BSs);                      altitude: up to several 100 m
  • High Altitude Platforms (HAPs) (floating-BSs);       altitude: ~20 km
  • Very Low Earth Orbit (VLEO) satellites;                  altitude: 200-1,000 km
  • Geostationary Orbit (GEO) satellites;                        altitude: 35,786 km

In the absence of a clear technology roadmap for the 2030s, the talk has, to a certain extent, an exploratory view point to stimulate further thinking and creativity. We are certainly at the dawn of a new era in wireless research and innovation; the next twenty years will be very interesting
