Distributed, networked communication systems, such as\u0026nbsp;relay beamforming networks are typically designed without\u0026nbsp;considering how the positions of the respective nodes might\u0026nbsp;affect the quality of the communication. However, in most cases,\u0026nbsp;the Channel State Information (CSI) observed by each network\u0026nbsp;node, per channel use is both spatially and temporally\u0026nbsp;correlated. In this talk, we address the problem of enhancing\u0026nbsp;Quality-of-Service (QoS) in power constrained, mobile relay\u0026nbsp;beamforming networks, by optimally exploiting relay mobility.\u0026nbsp;Adopting a spatiotemporal stochastic field model of the wireless\u0026nbsp;channel, we propose a novel 2-stage stochastic programming\u0026nbsp;formulation for specifying the relay positions at each time slot,\u0026nbsp;such that the QoS of the network is maximized on average, based\u0026nbsp;on causal CSI and under a total relay transmit power budget. The\u0026nbsp;motion control problem considered is shown to be approximately\u0026nbsp;equivalent to a set of simple subproblems, which can be solved in\u0026nbsp;a distributed fashion, one at each relay.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBiography. Athina P. Petropulu is Professor of the Electrical and\u0026nbsp;Computer Engineering (ECE) Department at Rutgers, having served\u0026nbsp;as chair of the department during 2010-2016. Before that she was\u0026nbsp;faculty at Drexel University. She held Visiting Scholar\u0026nbsp;appointments at SUPELEC, Universite\u0026#39; Paris Sud, Princeton\u0026nbsp;University, and University of Southern California. Her research\u0026nbsp;interests span the area of statistical signal processing,\u0026nbsp;wireless communications, signal processing in networking,\u0026nbsp;physical layer security, and radar signal processing\u0026nbsp;A. Petropulu is Fellow of IEEE and recipient of the 1995\u0026nbsp;Presidential Faculty Fellow Award given by NSF and the White\u0026nbsp;House. She has served as Editor-in-Chief of the IEEE Transactions\u0026nbsp;on Signal Processing (2009-2011), IEEE Signal Processing Society\u0026nbsp;Vice President-Conferences (2006-2008), and member-at-large of\u0026nbsp;the IEEE Signal Processing Board of Governors. She was the\u0026nbsp;General Chair of the 2005 International Conference on Acoustics\u0026nbsp;Speech and Signal Processing (ICASSP-05), Philadelphia PA. In\u0026nbsp;2005 she received the IEEE Signal Processing Magazine Best Paper\u0026nbsp;Award, and in 2012 the IEEE Signal Processing Society Meritorious\u0026nbsp;Service Award for \u0026quot;exemplary service in technical leadership\u0026nbsp;capacities\u0026quot;. She is IEEE Distinguished Lecturer for the Signal\u0026nbsp;Processing Society for 2017-2018.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003E\u003Ca href=\u0022https:\/\/events.vtools.ieee.org\/m\/44772\u0022\u003EPlease RSVP here.\u003C\/a\u003E\u003C\/strong\u003E\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EIEEE Distinguished Lecture, Atlanta Signal Processing\u0026nbsp;Chapter - Dr. Athina Petropulu, Rutgers University\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"IEEE Distinguished Lecture, Atlanta Signal Processing\u00a0Chapter - Dr. Athina Petropulu, Rutgers University"}],"uid":"27469","created_gmt":"2017-04-10 13:36:01","changed_gmt":"2017-04-13 21:12:03","author":"Kristen Bailey","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-04-26T13:00:00-04:00","event_time_end":"2017-04-26T14:00:00-04:00","event_time_end_last":"2017-04-26T14:00:00-04:00","gmt_time_start":"2017-04-26 17:00:00","gmt_time_end":"2017-04-26 18:00:00","gmt_time_end_last":"2017-04-26 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"https:\/\/events.vtools.ieee.org\/m\/44772","title":"RSVP Link"}],"groups":[{"id":"1182","name":"General"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EAlessio Medda\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Ca href=\u0022mailto:alessio.medda@gtri.gatech.edu\u0022\u003Ealessio.medda@gtri.gatech.edu\u003C\/a\u003E\u003C\/p\u003E\r\n","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
