The booming growth and rapid development in embedded systems, wireless communications, sensing techniques and emerging support for cloud computing and social networks have enabled researchers and practitioners to create a wide variety of Cyber-Physical-Social (CPS) Systems that reason intelligently, act autonomously, and respond to the users' needs in a context and situation-aware manner. The CPS systems are the integration of computation, communication and control with the physical world, human knowledge and sociocultural elements. It is a novel emerging computing paradigm and has attracted wide concerns from both industry and academia in recent years.
Generally, CPS systems collect massive data (Volume) from the physical world by various physical perception devices (Variety) in structured/semistructured/unstructured format and respond the users' requirements immediately (Velocity) and provide the proactive services (Veracity) for them in physical space or social space. These collected big data are normally high dimensional, redundant and noisy, and beyond the processing capacity of the computer systems.
This talk will present our latest research about a Big Data-as-a-Service framework which includes data representation, dimensionality reduction, processing (securely) and proactive service layers (including deep computation) aiming at representing and processing the big data generated from CPS systems and providing more valued smart services. Corresponding case studies in some applications such as smart home, campus and traffics will be shown to demonstrate the feasibility and flexibility of the proposed framework.

The advent of IoT, a few years back, opened up new avenues for smart-technology deployment which posed newer research challenges, having wide ramifications, affecting application and deployment scenarios in transportation, logistics, energy, health, cities and even, homes. Initially, these domains seemed too futuristic and unrealizable. They seemed too good to be true, with most of them being signed off as hype. However, with rapid advances in technology, as well as exposure of the populace to these technologies, has enabled the realization of these myths into actual technologies. These technologies are rapidly challenging the traditional approaches of transportation, logistics, healthcare, living and business. The rise in popularity, advancements and rapid commercialization of technologies such as smartphones, wearables, 3D printing, drones, cyber-physical systems, connected and autonomous vehicles, among many others, have caused the rise in popularity of IoT and has made it an essential technology for functioning of these previously mentioned technologies. The world is on the brink of an explosion of fully connected, autonomous and intelligent devices, with the capability of sensing its surroundings, making decisions and acting upon the decisions made and communication using the Internet as its backbone. These devices not only need minimal human supervision but, they may do away with the human supervision completely, in the near future. This trend is clearly visible with the rapid indulgence of technology powerhouses such as Google, Microsoft, Baidu and others into the domain of IoT, cloud and autonomous devices. The hypes of the past are rapidly converging into reality, with the use of IoT as the main driving force.

Internet of Things was proposed about a decade ago, and since then has attracted many research interests in both academia and industry. In the last few years, the industry has picked up the steam and developed a number of real-world applications with specialized hardware and system development.
In this talk I will give a brief overview on our effort in designing some basic theory related Internet of Things (or wireless networking and mobile computing in general), developing related prototype systems for verifying the theoretical results, and visioning future research directions in this area. I will use sensing and localization as running examples to illustrate our effort and endeavors in this fast-growing area.
In this talk, I will first give a quick review of our collaborated projects on large scale wireless sensor networking systems. I will then present our object localization and tracking using COTS RFID tags and readers. Tracking mobile RFID tags in real time has been a daunting task, especially challenging for achieving millimeter-level accuracy. I present several RFID-based systems for locating objects. One category is device-based where RFID tag is attached to the object-to-be-localized, and the other category is device-free method where no RFID tag is attached the object at all. For lab environment, we can track the mobile tags in real time with accuracy to a median of 5mm along the moving direction. In our year-long large-scale trial studies in real luggage sortation systems of two airports, our results show that Tagoram can achieve accuracy to a median of 63.5mm in these real deployments. The results are collaborated with research groups at Tsinghua University.

In a cooperative cognitive radio network, secondary users are able to negotiate with primary users for dedicated transmission opportunities through providing tangible service. Two novel and simple user cooperation frameworks are introduced to improve the spectral efficiency and utilization. To this end, an orthogonal signaling-based cooperation technology for leveraging the degrees of freedom in two-dimensional modulation is discussed. In the proposed framework, an SU is enabled to simultaneously transmit its own data and relay another user's packets in two orthogonal channels. Specifically, in the framework of user cooperation between PUs and SUs, a cross-layer design for cooperative communications between an active PU and an SU is first investigated. In the framework of cooperative spectrum leasing by a group of SUs, a cross-layer design for cooperation among SUs is then presented.
