Title: Strong coordination of signals and actions over noisy channels with two-sided state information

Abstract: In decentralized networks, communication devices must be able to cooperate, to take decisions in a distributed fashion and to reconfigure dynamically by reacting to changes in the environment. To achieve such behavior, efficient techniques to coordinate the actions of different nodes must be developed.
In this talk, we consider a two-node network with a noisy channel and two-sided state information, in which the input and output signals have to be coordinated with the source and its reconstruction.
We propose a joint source-channel coding scheme and derive inner and outer bounds for the strong coordination region. Moreover, we are able to give a complete characterization of the coordination region in some particular cases. Finally, we show that polar codes achieve the best known inner bound for the strong coordination region.

Date/Location: 4th July, 14h, TD-D Building Chappe, INSA Lyon.

Title: IF Neuron: theoretical study and application to digital communication

Abstract: In the context of digital communication, one main mechanism proposed in the literature to overcome the large consumption of MAC layers when establishing communications is called wake-up radio: The main processor is only waking up when receiving a specific signal, as for instance the node ID in the network. Unfortunately, since most of the wake-up receivers rely on standard micro-controller, they suffer a large decrease of energy efficiency. Nevertheless, if the wake-up receivers was designed with neuromorphic circuits, one could achieve high energy efficiency for IoT and ad hoc networks.

The main question that is tackled in this presentation is whether a neuro-inspired detection scheme using an Integrate-and-Fire neuron is reliable enough when one needs to detect a weak signal surrounded by noise.

(6) On 12th July I will be presenting a seminar at IETR in Rennes, hosted by Philippe Mary.

Title: Communication in Open Systems: From the IoT to the Nanoscale

Abstract: The large-scale nature and varying levels of coordination in modern communication systems means that they no longer can be viewed as isolated. That is, control in the form of resource allocation and scheduling cannot be done, either in a centralised or decentralised fashion, for all devices in the network. Necessarily, for a given transmission the quality of communication is influenced by the behaviour of devices external to those devices directly involved in the transmission. In the context of the Internet of Things, such a setting arises due to the multiple operators and uncoordinated nature of supporting wireless communication networks. In this talk, I will discuss design in the presence of external wireless IoT devices, leveraging our recent work on information theoretic limits for these systems. I will also introduce emerging communication strategies for nanoscale networks, which should also be viewed as open systems. These nanoscale networks are subject not only to the influence of other communication networks but also external biological processes. To begin understanding the capabilities of these communication networks, information theoretic models and their limits will be developed via new analogies to open wireless communication systems.
