Second, to build a relay-assisted mmWave\u0026nbsp;backhaul network with a tree topology, which consists a set of pre-defined logical links between BSs, the relay selection algorithm is enhanced to not only consider\u0026nbsp;controlling the intra-path mutual interference, but also have the ability to minimize the inter-path mutual interference as well. Several methods are also proposed to improve the feasibility of finding a solution where all logical links are interference-minimal. Third, upon a new interference model, through linear programming, the\u0026nbsp;traffic demand of small-cell BSs can be maximized in the mmWave backhaul network in either the downlink or uplink case. An efficient distributed scheduling\u0026nbsp; algorithm is also proposed, which can be deployed easily in the practical system. Fourth, as for deploying mmWave backhaul networks along the urban roadside\u0026nbsp;environment to provide 5G service to vehicles, a novel interference-minimal backhaul topology is proposed. Fifth, to enable the simulation of mmWave out-of-band\u0026nbsp;backhaul networks in ns-3, the design of a new mmWave backhaul module in ns-3 is proposed. On the other hand, the existing mmWave in-band backhaul module\u0026nbsp;in ns-3 is also extended to support the simulation of basic functionalities of the mmWave out-of-band backhaul network.\u0026nbsp; \u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Design and Analysis of Millimeter-wave Backhaul Networks in Urban Environments "}],"uid":"28475","created_gmt":"2019-08-08 20:55:47","changed_gmt":"2019-08-08 20:55:47","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-08-20T10:30:00-04:00","event_time_end":"2019-08-20T12:30:00-04:00","event_time_end_last":"2019-08-20T12:30:00-04:00","gmt_time_start":"2019-08-20 14:30:00","gmt_time_end":"2019-08-20 16:30:00","gmt_time_end_last":"2019-08-20 16:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
