Description

We are pleased to invite you to the Asa Briggs guest lecture on Wednesday 6 September 2017, in the CHICHESTER 1 Lecture Theatre.

Prof. Victor C.M. Leung, from University of British Columbia (UBC) Canada, will be giving a talk on “Internet of Things – Some Challenges and Recent Results”. Abstract of his talk is below.

The seminar is going to take place between 12:00 – 13:00 and sandwiches will be served.

Abstract:
The Internet of Things (IoT) extends the Internet to connect not only computers and smart devices carried by people, but “things” with embedded sensors, actuators, and networking capabilities. IoT will enable many new services and applications such as smart grids, intelligent transportation, e-health, smart homes/buildings/offices/factories, which will be an integral part of the future smart cities. However, widespread deployment of IoT in society, especially in the context of smart cities, is challenged by a number of issues, most notably the utility, efficiency and security of IoT solutions. In this presentation, we shall focus on the first two of these issues. Conventionally IoT applications have been provisioned with dedicated protocol stacks that are fine tuned for the specific applications, which limit the utility of such systems to other possibly new applications that were not considered when these “application silos” were designed and implemented. Following the trend of network functions virtualization, software-defined networking, and virtualized cloud computing services, we present a framework for wireless sensors as a service, aided by sensor-cloud integration. Due to the distributed and heterogeneous nature of this framework and the fact that computations are increasingly migrated to the network edge, programming such a system, especially coordinating the multitude of software components that are deployed on the edge computing devices, is challenging. We present some results on programming model and process coordination mechanisms to address this challenge. Energy efficiency is another important issue in the design of IoT systems, due to the potentially widespread deployment of IoT devices and the fact that many such devices are battery operated and deployed in situations where battery replacement is awkward if not impossible. We address this issue from the sensor-cloud perspective by developing a sensor sleep scheduling scheme driven by the needs of sensor data by applications. On the other hand, we are developing embedded radio and enabling protocol for IoT devices that incorporate energy harvesting and message-driven wake-up capabilities. We conclude the presentation with a brief discussion on open problems and future research directions.
