WP Welcome and workshop presentation 26 November 2017 10:00-10:15 Room 302, 3rd Floor, Building 26 ICQTK ICQT2017 Keynote The impact of the Sharing Economy on mobility Costas Courcoubetis (Singapore University of Technology and Design) It is widely believed that ride sharing, the practice of sharing a car such that more than one person travels in the car during a journey, has the potential to significantly reduce congestion by filling up cars more efficiently. By analyzing a game-theoretic model will large number of players we find that the ratio of ownership to usage costs is the crucial determinant that decides how ride sharing is organized in society. If this ratio is low, ride sharing is offered as a peer-to-peer (P2P) service, and if this ratio is high, ride sharing is offered as a business-to-customer (B2C) service. In the P2P case, rides are initiated by drivers only when the drivers need to fulfill their own transportation requirements. In the B2C case, cars are driven all the time by full time drivers taking rides even if these are not motivated by their private needs. Our analysis specifies how car ownership and congestion are effected by platform prices, cost parameters, and the distribution of the individuals' types. In particular we discover that traffic and ownership may increase as the ownership cost increases, and that a revenue maximizing platform might prefer a situation where cars are driven with only a few seats occupied, creating high congestion. In this talk we like to discuss regulation policy design issues, avoiding excess congestion but profiting from the sharing economy. 10:15-11:00 2017-11-26T10:15:00+09:00 2017-11-26T11:00:00+09:00 Room 302, 3rd Floor, Building 26 Bruno Tuffin (Inria Rennes, France) CB Coffee break 11:00-11:30 Room 302, 3rd Floor, Building 26 MC1 Session 1: Economics of spectrum management 11:30-13:00 2017-11-26T11:30:00+09:00 2017-11-26T13:00:00+09:00 Room 302, 3rd Floor, Building 26 Kyoko Yamori (Asahi University, Japan) 11:30 12:00 1570375159 ICQT1.1 Simulation Model for Regulatory Impact Assessment of Next Generation Spectrum Authorization Regimes 9th International Workshop on Internet Charging and QoS Technologies - Full papers Stephan Wirsing 857079 University of Vienna Austria 1 Peter Reichl 1222927 University of Vienna Austria 0 12:00 12:30 1570378350 ICQT1.2 Duopoly Price Competition in Secondary Spectrum Markets 9th International Workshop on Internet Charging and QoS Technologies - Full papers Xianwei Li 524025 Suzhou University China 0 Bo Gu 827267 Kogakuin University Japan 0 Cheng Zhang 524025 Waseda University Japan 0 Zhi Liu 533679 Shizuoka University Japan 1 Kyoko Yamori 166307 Asahi University Japan 0 Yoshiaki Tanaka 92747 Waseda University Japan 0 12:30 13:00 1570378445 ICQT1.3 Regulating Wireless Access Costs for Not Vertically Integrated Content Providers 9th International Workshop on Internet Charging and QoS Technologies - Full papers George Kesidis 1499473 Pennsylvania State University USA 0 Xinyi Hu 12901 Pennsylvania State University USA 0 Seung Jun Baek 12901 Korea University Korea 0 Lunch Lunch 13:00-14:30 Restaurant Mori-no-Kaze, 15F, Bldg.26 ICQT2 Session 2: Wireless services 14:30-16:00 2017-11-27T14:30:00+09:00 2017-11-27T16:00:00+09:00 Venue: Room 302, 3rd Floor, Building 26 Patrick Maille (Institut Mines-Telecom, Rennes, France) 14:30 15:00 1570375144 ICQT2.1 Wireless Sensor Network-based service provision: a three-sided market model 9th International Workshop on Internet Charging and QoS Technologies - Full papers Luis Guijarro 1507099 Universitat Politecnica de Valencia Spain 1 Jose Ramon Vidal 3211 Universitat Politècnica de València Spain 0 Vicent Pla 655707 Universitat Politecnica de Valencia Spain 0 Maurizio Naldi 655707 University of Rome Tor Vergata Italy 0 15:00 15:30 1570375262 ICQT2.2 Analyzing Human Mobility and Social Relationships from Cellular Network Data 9th International Workshop on Internet Charging and QoS Technologies - Full papers Zheng Liu 1454447 Beijing University of Posts and Telecommunications China 1 Yuanyuan Qiao 1454447 Beijing University of Posts and Telecommunications China 1 Siyan Tao 1454447 Beijing University of Posts and Telecommunications China 1 Wenhui Lin 1454447 Aisino China 1 Jie Yang 1454447 Beijing University of Posts and Telecommunications China 1 15:30 16:00 1570378939 ICQT2.3 Cost- and Energy-Aware Multi-Flow Mobile Data Offloading under Time Dependent Pricing 9th International Workshop on Internet Charging and QoS Technologies - Full papers Cheng Zhang 1485254 Waseda University Japan 1 Bo Gu 1511216 Kogakuin University Japan 0 Zhi Liu 869349 Shizuoka University Japan 0 Kyoko Yamori 393083 Asahi University Japan 0 Yoshiaki Tanaka 393083 Waseda University Japan 0 ICQT3 Session 3: Quality of Service 16:30-17:30 2017-11-27T16:30:00+09:00 2017-11-27T18:00:00+09:00 Room 302, 3rd Floor, Building 26 Bo Gu (Kogakuin University, Japan) 16:30 17:00 1570373793 ICQT3.1 Capacity Optimization for Ultra-Reliable Low-Latency Communication in 5G - The SON Perspective 9th International Workshop on Internet Charging and QoS Technologies - Full papers Elke Roth-Mandutz 1211913 Fraunhofer IIS Germany 1 Abubaker Matovu Waswa 1403357 Technische Universität Ilmenau Germany 0 Andreas Mitschele-Thiel 154796 Ilmenau University of Technology Germany 0 17:00 17:30 1570378921 ICQT3.2 User Association for Load Balancing in Cellular Network with Hybrid Cognitive Radio Relays 9th International Workshop on Internet Charging and QoS Technologies - Full papers Hongfu Guo 1155545 Beijing University of Posts and Telecommunications China 0 Fanqin Zhou 1155545 Beijing University of Posts and Telecommunications China 0 Lei Feng 1155545 Beijing University of Posts and Telecommunications China 0 Peng Yu 1155545 Beijing University of Posts and Telecommunications China 0 Wenjing Li 1155545 Beijing University of Posts and Telecommunications China 0 CR Closing remarks 17:30-17:40 Room 302, 3rd Floor, Building 26
