This course is given as a specialization (M2) module for the ACN master, joint between École Polytechnique and Télécom ParisTech. It focuses on wireless self-organizing networks that shall become an important part of the Internet of Things, whatever this means. Vehicular networks, sensor and actuator networks, body area networks, delay tolerant networks or, more generally ad-hoc networks share some common characteristics that we will explore in this series of lectures given by Thomas Clausen and myself. You will find below the slides of the lectures I gave in 2014/2015.
