Title: IEEE 802.11ax: Highly Efficient WLANs

Abstract:

In 1985 the US Federal Communications Commission (FCC) made several wireless spectrum bands available without a government license, known as “garbage band”, for Industrial, Medical, and Scientific (ISM) purposes, which unleashed a wave of innovations in the telecommunication industry that fundamentally changed humans experience and the interaction with wireless networks. This wave of innovations manifests itself in the introduction of affordable networking technologies capable of satisfying users’ needs in terms of mobility and connectivity. Among those technologies the Wi-Fi networking based on IEEE 802.11 Wireless LAN (WLAN) standards has distinguished itself as the technology of choice for the masses to satisfy their networking requirements at an affordable cost. Wi-Fi devices now are being deployed in diverse environments. These environments are characterized by the existence of many access points (AP) and mobile nodes in geographically limited areas. Increased interference from neighboring devices and severe collisions from channel contention in dense environments give rise to network performance degradation. Hence, recently, a new effort to seek fundamental improvement of IEEE 802.11, known as IEEE 802.11ax (a.k.a. 802.11 HEW), was approved to deliver a new generation of WLANs. This talk will firstly introduce the history and the state-of-the-art operation of WLANs protocol. The expected features and challenges for designing future WLANs protocol will also be discussed. Next, in this talk we will summarize the IEEE 802.11ax standardization activities in progress and introduce the key features proposed in the 802.11ax amendment. Finally, in this talk we will also address coexistence issues between the different communication technologies operating in the same band since LTE- advanced (4G) and 5G are also planning to make use of the unlicensed bands.

Title: FrameTalk: Human and Picture Frame Interaction through the IoT Technology

Abstract:

Picture frame has been used to demonstrate artworks since ancient times. The importance of the frame was emphasized by a quote of American novelist Chuck Palahniuk: “It’s funny how the beauty of art has so much more to do with the frame than the artwork itself.” Although the concept of frame plays a significant role in art design, traditional picture frames do not allow interaction with human. To provide another dimension of artwork demonstration of picture frames, we utilize the Internet of Things (IoT) technology to create human and picture frame interaction. Specifically, an application-layer IoT device management platform called IoTtalk is used to quickly establish connections and meaningful interactions between IoT devices without concerning the lower-layer IoT protocols.

The IoT devices are connected to the IoTtalk engine in the Internet through wireline or wireless technologies, where an input device sends data to the IoTtalk engine and an output device receives the data from the IoTtalk engine. The frame and human interaction is achieved by implementing an output device called frameTalk in IoTtalk, which provides animation in a digital frame to be controlled by the input devices (typically a smartphone). The frameTalk device is cyber (an animation program) that can be displayed in specific frame hardware or the screen of any computing device. We describe the functional block diagram of the frameTalk device and its default applications. Then we show two frameTalk application examples. The first example is CalligraphyTalk that allows the audience to interact with the frame to write the poems. A CalligraphyTalk artwork called CloudRising won a Finalists’ Award in Asia Digital Art Award FUKUOKA Japan in 2018. The second example is PortraitGuess that allows the audience to guess historical figures through the frame. PortraitGuess was one of the 2017 FarEastone IoT Contest award recipients. We measure the delays between the smartphone and the frameTalk device, and develop both analytic and simulation models

Title: Big-Data Driven Anomaly Detection in Mobile Wireless Networks

Abstract:

The demand on and assurance of ubiquitous access and information exchange in future wireless networks will yield massive data over wireless networks. The future mobile wireless networks will essentially evolve to be highly smart as well as autonomous. Consequently, the network needs to be able to find anomaly among vast networking behaviors, data, and signals, such that alarms can be reported to the network managers, which, however, is challenging due to the massive magnitude of data records as well as difficulty in using wireless signals flying over the air. This talk addresses big-data driven anomaly detection in mobile wireless networks with emphasis on two scenarios: 1) Activity-anomaly detection in cellular networks based on big call-record data; 2) Intrusion detection in massive machine-type communications driven by big air-interface data. Future research topics on big data applications and over mobile wireless networks will be also discussed.
