Title: Mechanism design in on-demand transport

Abstract: Uber is one of several recent companies adopting a business model that lies in stark contrast with the standard approach used by taxi services. Underlying Uber’s business model is a new architecture–based on a market mechanism–which governs how commuters, drivers, and the company interact with each other. In this talk, we develop a new general model for on-demand transport networks with self-interested passengers and drivers. With this model, we introduce market mechanisms to allocate and price journeys, as well as the market formation subproblem. By analysis and simulation, we characterize the performance of the mechanisms and discuss insights using data obtained from a real on-demand transport provider.

(4) Mauro de Freitas from Université Lille 1 has been visiting me in Lyon from the 12th to 18th May. He presented some of our joint work on impulsive noise in communications. Here are the details:

Title: Wireless Networks in Dynamic Interference

Abstract: This work is motivated by the Internet of Things, where devices can transmit for very short periods of time. A consequence is that interference is dynamic; that is, the active transmitter set can change very rapidly. In this case, the Gaussian interference model may not be the most appropriate. In fact, dynamic interference can be better modeled by impulsive interference, particularly alpha-stable noise. In this talk, we characterize the capacity in the presence of alpha-stable noise via upper and lower bounds, and consider the behavior in medium interference regimes. This analysis reveals many similarities with the well understood Gaussian case, such as outage probability characterizations and power control in parallel channels.
