Title: Slicing the next Generation Telecom Core Networks: Service Admission Control
Presented by: Prof. Vahid Shah-Mansouri, University of Tehran, Iran

Date and time:  Friday, August 31, 2018 at 11 am

Location: Room 418, Macleod Building, UBC, 2356 Main Mall, Vancouver

Abstract: Agile service provisioning for services with strict service level agreement (SLA) requirement is a new paradigm for service providers and network operators. A new service requires resources from different parts of the network. It requires independent life cycle, isolation from other services, and independent management. Resource allocation as well as life cycle management of new services, which co-exist with already deployed services arises new challenges. Network slicing is proposed to support simultaneous independent services on a single network. A network slice is viewed as a logical end-to-end network that can be dynamically created, modified, and released. A network slice provides a service with specific SLA. In this talk, I will review the concept of slicing for the core network. Then, we propose an admission control model for the new services requested in a telecom operator with dynamic slices.

Title: A Novel System for 5G Indoor Service Provisioning
Presented by:  Prof. Pin-Han Ho, University of Waterloo

Date and time:  Thursday, August 2, at 11 am

Location: Room 418, Macleod Building, UBC, 2356 Main Mall, Vancouver

Abstract: The talk presents a novel distributed antenna access architecture that allows the antenna units of an RRU to be distributed over a wide geographical range, instead of being hosted locally at the RRU, so as to achieve a cost-effective solution of 5G indoor service provisioning. The proposed architecture takes advantage of multi-pair LAN cables to support simultaneous transmission of multiple intermediate frequency (IF) signals between the RRU and each distributed antenna unit (DAU), so as to meet the high bandwidth requirements and overcome the non-line-of-sight nature of the indoor environment. To explore the capacity of the multi-pair cables, we introduce a real-time multi-pair Air-to-Cable (MP-A2C) scheduler that allows for a graceful mapping between the radio signals of each DAU and sub-carriers of the cable twisted pairs. We will show via extensive simulation that the formulated optimization problem based on the A2C mapping task can easily lead to quasi-optimal schedules.

IEEE ComSoc Distinguished Lecture

Title: Economic Thinking of Communication Networks
Presented by:  Prof. Jianwei Huang, The Chinese University of Hong Kong

Date and time:  Monday, July 9, at 11 am

Location:  Room 418, Macleod Building, UBC, 2356 Main Mall, Vancouver

Abstract: Today’s communication networks are highly complex, carry heterogeneous traffic in diverse environments, and are often owned by multiple profit-making entities. To successfully maintain, optimize, and upgrade such large distributed networks, it is important to design new economic incentive mechanisms as well as develop new technologies. The market deregulation of the telecommunication industry in many countries makes such economic consideration even more urgent, as there are often conflicting goals between the regulators and the commercial operators. We will first illustrate how economics can help us better understand the networking industry reality, predict user behaviors, envision new network services, and provide policy recommendations. Then we will focus on the case study of incentive mechanisms for user-provided networks (UPNs). UPNs is a new communication paradigm, which enables users to improve their communications experiences by exploiting the diverse communication needs and resources of other users. The success of UPNs, however, relies on carefully designed incentive mechanisms that effectively encourage users’ voluntary participations and cooperations. We will introduce a new paradigm of cooperative video streaming based on the concept of UPN, where mobile users crowdsource their Internet connectivities and adaptively choose video downloading sequences and streaming qualities. We will introduce a multi-dimensional auction framework, which effectively incentivizes users to cooperate in a distributed fashion.

Title: Physical Layer Millimeter-wave Communications
Presented by:  Prof. Danijela Cabric, UCLA

Date and time:  Monday, June 11, 2018, at 4 pm

Location: Room 418, Macleod Building, UBC, 2356 Main Mall, Vancouver

Abstract: Millimeter wave (mmWave) communications is viewed as the key enabler of 5G cellular networks due to vast spectrum availability that could boost peak rate and capacity. Due to increased propagation loss in mmWave band, transceivers with massive antenna array are required to meet link budget. While massive antenna arrays enable high gain, directionality and user multiplexing, practical realizations face many challenges in radio design and physical layer processing. In this talk, we first review emerging massive array architectures for mmWave communications and compare their performance, power consumption, and cost with comprehensive hardware block model under typical application use cases. We then discuss two important physical layer design aspects in mobile mmWave networks: directional link establishment via initial access and directional link maintenance via mmWave channel tracking. Lastly, we present the state-of-the-art designs of current mmWave standards, discuss their limitation and provide perspectives on innovative approaches for performance boosts and hardware improvements.

Title: Story Forest: Organizing Massive News Documents via AI and Natural Language Processing
Presented by:  Prof. Di Niu, University of Alberta

Date and time:  Friday, February 23, 2018, at 11 am

Location:Room 418, Macleod Building, UBC, 2356 Main Mall, Vancouver

Abstract: I will describe our recent experience of implementing a news content organization system in collaboration with Tencent that can discover hot events from vast streams of breaking news and connect events into stories for easy viewing. Our real-world system has distinct requirements in contrast to previous studies on document topic modeling and detection, in that 1) an event does not only contain articles of a similar topic, but is a cluster of documents that report exactly the same physical incidence; 2) we must evolve news stories in a logical and online manner. In solving these challenges, we propose Story Forest, a state-of-the-art news content organization system based on artificial intelligence and natural language processing. I will briefly describe the key enabling technologies in Story Forest, including identifying the relationship between text objects, e.g., whether they talk about the same event or whether one article is a follow-up of another, based on deep learning. Our system has been deployed in Tencent QQ Browser mobile app.

Title: Gaussian Residual Bidding-based Coalitional Framework for Renewable Energy Market
Presented by:  Prof. Hongseok Kim, Sogang University, Korea

Date and time:  Friday, September 29, at 11 am

Location: Room 418, Macleod Building, UBC, 2356 Main Mall, Vancouver

Abstract: To stabilize output variability of distributed renewable energy sources (RESs), integrating large-scale RESs is highly utilized, and aggregated RESs are treated almost as any other conventional generators in existing electricity markets. In this talk we first propose a coalitional framework to cope with the uncertainty of RESs when RES owners can participate in a wholesale electricity market as sellers, where a market operator financially penalizes RES owners for deviations between day-ahead and real-time markets. Our theoretical approach incentivizes participants in a coalition by mitigating penalty fees caused by renewable variability. Furthermore, we propose a bidding strategy called Gaussian residual bidding (GRB) to maximize a coalition gain of participants. We prove that the considered game is convex game when GRB is used for all participants. Our extensive simulations with real data demonstrate that the proposed bidding strategy combined with the coalitional framework outperforms other bidding strategies as well as non-coalition cases under various market scenarios. Our results exhibit the revenue of GRB is improved up to 200% compared to the existing empirical quantile bidding and forecast bidding strategies.

Title: EdgetIoT: Mobile Edge Computing for the Internet of Things

Presented by: Prof. Nirwan Ansari, New Jersey Institute of Technology, USA
IEEE Communications Society Distinguished Speaker

Abstract:  In order to overcome the scalability problem of the traditional Internet of Things (IoT) architecture (i.e., data streams generated from distributed IoT devices are transmitted to the remote cloud via the Internet for further analysis), mobile edge computing has been proposed to provision IoT by handling the data streams at the mobile edge. Specifically, each base station is connected to a fog node, which provides computing resources locally. On the top of the fog nodes, the software defined networking (SDN) based cellular core is designed to facilitate packet forwarding among fog nodes. Meanwhile, we propose a hierarchical fog computing architecture in each fog node to provide flexible IoT services: each user’s IoT devices are associated with a proxy VM (located in a fog node), which collects, classifies, and analyzes the devices’ raw data streams, converts them into metadata, and transmits the metadata to the corresponding application VMs (which are owned by IoT service providers). Each application VM receives the corresponding metadata from different proxy VMs and provides its service to users. In addition, a novel proxy VM migration scheme is proposed to minimize the traffic in the SDN-based core.
