Since the second World War, technological (r)evolutions have been further integrating our societies, causing a disruption not only in our life styles and know-how but also mentalities. Environmental awareness is a good example. Nowadays, everyone wants to be able to produce his/her own “green” and local energy. However, the French power grid, very...

The Smart Grid (SG) aims to transform the current electric grid into a “smarter” network where the integration of renewable energy resources, energy efficiency and fault tolerance are the main benefits. This is done by interconnecting every energy source, storage point or central control point with connected devices, where heterogeneous SG applicat...

The Smart Grid (SG) aims to transform the current electric grid into a "smarter" network where the integration of renewable energy resources, energy efficiency and fault tolerance are the main benefits. A Wireless Sensor Network (WSN) controlling and exchanging messages across the grid is a promising solution because of its infrastructure free and...

La transformation des réseaux électriques existants en Smart Grids (SGs) ambitionne d'en faciliter l'automatisation pour une meilleure qualité de service tout en y facilitant l'intégration de sources d'énergies renouvelables. Cette évolution vers un réseau électrique plus intelligent nécessite de pouvoir transmettre en temps réel un maximum de donn...

The transformation of existing power grids into Smart Grids (SGs) aims to facilitate grid energy automation for a better quality of service by providing fault tolerance and integrating renewable energy resources in the power market. This evolution towards a smarter electricity grid requires the ability to transmit in real time a maximum of data on...

The Internet of Thing is an ongoing revolution which promises to interconnect most of our world with billions of connected devices. Hence, data routing and prioritization in IoT is a main challenge in this gigantic network. This is all the more true for the Smart Grids data management where heterogeneous applications and signalling messages have di...

L'acheminement des données dans l'Internet des Objets a depuis toujours été un défi. En effet, il s'agit de router des données dans un réseau caractérisé par une hétérogénéité omniprésente : logicielle, matérielle, mais aussi applicative. En réponse, l'IETF (Internet Engineering Task Force) a standardisé le protocole de routage généraliste RPL (Rou...

This thesis is about wireless multi-hop networks such as wireless sensors networks or hybrid sensor/actuator networks and actuator networks. Those kinds of networks are composed of independent entities (nodes, i.e. the robots) which have very limited computing and memory capabilities. Moreover, they are battery powered and have to work in an effici...

One of the most current routing families in wireless sensor networks is geographic routing. Using nodes location, they generally apply a greedy routing that makes a sensor forward data to route to one of its neighbors in the forwarding direction of the destination. If this greedy step fails, the routing protocol triggers a recovery mechanism. Such...

Controlled mobility is one of the most complex challenges in Wireless Sensor Networks (WSN). Only a few routing protocols consider controlled mobility in order to extend the network lifetime. They are all designed to optimize the physical route topology from a source to a destination. However, there is often more than one sensor which reports an ev...

In typical mobile wireless sensor networks, flows sent from collecting sensors to a sink could traverse inefficient resource expensive paths and experience arbitrary delays. This is particularly problematic in event-based sensor network where flows are of great importance. In this paper, we are interested in energy-aware routing algorithms that exp...

This paper addresses the usage of actuators (sensors with controlled mobility) for routing in wireless sensor and actuator networks. Different routing protocols have been proposed to improve routing in terms of energy efficiency through the use of controlled mobility enabled sensors . We introduce MobileR. Unlike literature proposals also using act...
