09:00 - 09:45: WT03-S1: Morning Keynote

Prof. José M. F. Moura: Distributed Localization for Interconnected Devices: An Iterative Linear Solution

IoT interconnects ever more physical devices that are instrumented with embedded electronics, sensors of different modalities, and actuators. To make full use of IoT and expand the range of potential applications, for example, tracking resources deployed in Hospital environments, or to manage deployed assets, it is important to localize them efficiently, not only outdoors, but, and increasingly more relevant, indoors where GPS is not available. To minimize infrastructure, communications, and power needs, these instrumented devices should cooperate with other nearby objects. In this keynote, I will present a distributed (cooperative) solution that solves the essentially nonlinear localization (triangulation) problem by an iterative linear algorithm that asymptotically converges to the correct localization of each and every device. I will discuss the minimal requirements for convergence and extensions of the basic algorithm to account for motion and noise.

José M. F. Moura, www.ece.cmu.edu/~moura, is the Philip L. and Marsha Dowd University Professor at CMU, with interests in signal processing and data science. He invented (with Alek Kavcic) a patented detector found in at least 60% of the disk drives of all computers sold worldwide in the last 13 years (over 3 billion and counting) – the subject of the recent settlement (February 2016) of $750 Million between CMU and Marvell, the largest settlement ever in the information technologies IP area and 3rd largest overall. He is (2016) IEEE VP for Technical Activities, IEEE Board Director, and was President of the IEEE Signal Processing Society (SPS), and Editor in Chief for the Transactions on SP. Moura received the IEEE SPS Technical Achievement Award and Society Award. He is Fellow of the IEEE and of AAAS, corresponding member of the Academy of Sciences of Portugal, Fellow of the US National Academy of Innovators, and member of the US National Academy of Engineering.

Dr. Christos Laoudias: Cellular Network Localization: Current Challenges and Future Directions

Slides: Keynote by C. Laoudias

Positioning technologies are important to cellular operators for enabling a variety of network planning and optimization features, while offering the opportunity to open new revenue streams through the monetization of user location data. This talk will first discuss industry interests with respect to the requirements of operators in existing location-dependent processes and envisioned location-aware application scenarios ranging from network event root cause analysis to indoor gaming and retail analytics. The technology landscape will be outlined next through an overview of commercial localization solutions for network operators. In the following, selected technical challenges in user/event localization will be presented focusing on solutions that leverage the high volume of measurement reports recorded at the network side as part of standard network operation. Such challenges include indoor/outdoor identification, 3D location, and mobility state estimation among others. Finally, future directions related to network-based positioning will be discussed in view of recent industry trends, such as network densification, and upcoming communication technologies in the context of 5G that can be greatly assisted by the availability of user location information.

Dr. Christos Laoudias has recently joined the KIOS Research and Innovation Center of Excellence at the University of Cyprus contributing to various projects related to localization, tracking, and navigation in telecommunication and smart camera networks. Before that he was leading the geolocation technology research in Huawei Ireland Research Center working on the design of data-driven positioning solutions for cellular network planning and optimization. He holds a Diploma in Computer Engineering and Informatics (2003) and a M.Sc. in Integrated Hardware and Software Systems (2005) from the University of Patras, Greece, and a Ph.D. in Computer Engineering from the University of Cyprus (2014). During his Ph.D. he coached the development of several award-winning indoor localization prototype systems, which have been released under open-source license, and for his doctoral research work he received the Alpha Bank Cyprus Award for "Creative Research and Innovation". His research interests include positioning and tracking technologies, mobile and pervasive location-awareness, fault-tolerant location estimation, and location-based services.
