Quebec Ecole Polytechnique (University of Montreal), Canada


Wireless communication and radar sensing are two of the most prominent applications of radio technology. In the past, these two systems operate differently and independently. However, if implemented, the system fusion of wireless communication and radar sensing would definitely bring up many benefits such as architecture unification, simplification, and miniaturization, functional reconfiguration and fusion, and especially efficiency enhancement and cost reduction. This presentation reviews the emerging advances in the waveform design and system development for multifunctional wireless systems that integrate both communication (radio) and sensing (radar) functions. State-of-the-art communication-radar (or radio-radar) modulation schemes are presented and their features are discussed with reference to the transceiver architecture fusion. Theoretical and experimental research results on integrated communication and radar T/R platform are highlighted to showcase the current system development. Future research topics in this direction are also pointed out.

Autonomous Navigation in a Human Environment
Prof. Anne Spalanzani
e-Motion team, LIG Laboratory, Pierre-Mendès-France University, France


Autonomous robot navigation in dynamic and human populated environments is still a challenging problem where the main addressed aspect in the state of the art has been the safety of the robot.

The assumption that environment is populated by human beings introduces a new important aspect: to include social awareness in the navigation solutions. Most of the previous approaches supposed that people are moving independently and considered people as dynamic obstacles or non-static objects. Recently, the social awareness issue has been addressed by considering humans not only as dynamic obstacles that respond to physical properties but also as social entities with intentions and feelings that follow social conventions according to psychological properties.

The main difficulties related to the presented problem are: (1) the uncertainty inherent to the future state of physical world. Models for the prediction of the most likely situation of the environment and the observed moving entities must be included. The representation of the environment must permit a fast updating with the new observations and be available when the navigation strategy requires information. (2) The uncertainty is linked to the perception of the physical world. Each sensor has a particular model with specific advantages and drawbacks therefore a robust fusion technique of data coming from multiple sensors must be implemented considering uncertainty. Robust real-time techniques are needed in order to detect and track humans in the environment providing useful information to reach high level reasoning on scene situations. Many robust current techniques employed to register human motion rely on invasive sensors which are not suitable for common life settings. (3) Mathematical models capable to reproduce social behavior in practice must be developed. While a perfect model of human behavior could not be available, some techniques have already been used to replicate expected social behavior in robotic fields. Navigation techniques must rely on that kind of models both to understand the scene and to filter non socially acceptable behaviors. Social conventions are a creation of human societies; they are difficult to model because they include always a subjective component invisible to sensors, they are situation dependent and very adaptive. But their function as regulator of social behaviors makes them essential to reach social awareness. (4) The navigation strategy to use must produce collision free solutions based on the dynamic environment model, social conventions model and robot dynamic properties. The motion planning algorithm chosen must reach equilibrium between the reactive properties desired in a dynamic environment with the stable solutions of a global planner.

This talk will present a socially-aware navigation method including both an assessment of a risk of collision using predictive models of moving obstacles, and an assessment of accordance with social conventions. Human management of space (personal space, o-space, activity space...) inspired from sociology and social robotics literature is integrated, but also models of behavior that enable the robot to make medium-term prediction of the human positions.

Radio-Frequency Energy Harvesting: Rectenna and Rectifier
Prof. Jean-Marc Duchamp
UJF-IMEP LAHC, Grenoble INP, France


Nowadays wireless power transfer is a promising technique for the long-term power supply of embedded wireless systems; e.g. heath applications (glucose measurement, body temperature, heart rate, etc…) or industrial applications (gas detection sensor, temperature measurement, …). These systems need low power electronic and alternatives for battery feeding. Several research teams are working on the possibility to create autonomous systems by ambient energy harvesting (electromagnetic, solar, vibration, thermal, etc ...).

The photovoltaic energy can provide a significant recovered power, 5 µW (panel size: 150 µm x 150 µm). A second solution is the vibration energy available, this source can provide up to 335 µW (piezoelectric, 2.25 m.s-2). Another possibility is the use of thermal energy with a possible recovery of about 250 µW (ambient indoor temperature). An interesting solution is based on the recovery of a radio frequency (RF) signal for supplying a DC power. It is possible to consider collecting up to 100 µW/cm².

This paper focuses on the state of art on RF harvesting. In a first part we describe the various solutions published of rectenna and their perfomances.

In a second part we present a new approach to a high-efficiency rectifier circuit design at 2.45 GHz, based on the principle of a "remix” successive of the harmonics generated by the diode. To validate this method, we developed a rectifier circuit capable of recover signals at 2.45 GHz with a high RF-DC efficiency conversion. The prototype has a RF-DC conversion efficiency of 70.4% for an RF input power of 0 dBm at 2.45 GHz.

P. Martinet, A. Abou Moughlbay, P. Long
UJF-IMEP LAHC, Grenoble INP, France


Complex systems like humanoid robots, multi arms systems, even platoon of vehicles, are difficult to handle because on their internal complexity and on the classical way of modeling used in robotics. Since the end of the eighties, a novel concept was introduced in order to formalize the task to be done not as a function of the internal joints of the robot but as a function of a set of interaction between the robot and the environment: it is named sensor based control.

We will present the road which has been followed in the last decades and present the current work done in this area. We will illustrates through three applications the main concepts. Two applications will concern humanoid robots (HRP2 and NAO), and the last one will be focused on a multi arms system (3 arms) used in order to perform dual arm beef muscle separation.

Improvement Performance of Multi-hop Ad-hoc Networks based on Cross-layer Design
Quang-Khanh Nguyen, Van-Duc Nguyen
School of Electronics and Telecommunications


A new MAC and Network cross layer protocol for OFDMA-based Multi-hop Ad-hoc Networks is proposed. In wireless network, when a route is established, the radio resource allocation problems at MAC layer may decrease the end to end performance proportionally with the length of each route. The contention at MAC layer may causes routing protocol to respond by finding new routes and routing table updates. The cross layer protocol allows layers to exchange state information in order to solve the problem and obtain higher performance. The proposed MAC and Network optimized cross layer protocol based the dynamic Sub-channel Assignment Algorithm in to ensure the performance of ad-hoc and multi-hop networks is significantly improved.

Energy management in smart building
Minh-Hoang Le
Department PSI - MICA


Homes and offices are key elements in the sustainable urban development because they consume a large part of the electricity production in European countries. Because of the increasing part of renewable energy in electricity production, which is difficult to control, consumers will have to become more involved in the grid management by reducing but also by adjusting their consumption in order to reach equilibrium between production and consumption on the grid, on one hand, and to limit the use of production means with high emission of CO2 on the other hand. The objective is to optimize the energy consumption (electrical and thermal loads) and production (local sources and available generators) according to various criteria such as: the cost to the user, reducing the negative impact on the environment, smoothing peak consumption energy while maintaining the comfort of the user. The available flexibilities of the services provided by domestic appliances are used to compute optimal energy plans. These flexibilities are associated to time windows or heating storage abilities. A constraints formulation of the energy allocation problem is proposed. A derived mixed linear program is used to solve this problem. The energy consumption in houses is very dependent to uncertain data such as weather forecasts and inhabitants' activities. For its operation, the system will rely on weather forecasts to anticipate thermal and photovoltaic resources. It also gradually learns the user behavior to adapt to their needs. Various examples of apartments are used to illustrate the validity of the proposed methods.

Minh-Thuy Le
Department PSI - MICA


The activities of passenger and goods transport are constantly increasing worldwide and especially in the European Union, including the edge of tolls. To improve the fluidity and reduce the risk of congestion, one of the solutions is automatic toll payments more efficient. This free-flow electronic toll collection system (Free-Flow ETC) allows a payment without stopping vehicles on the road. It includes two main components: the vehicle identification using/including transponders UHF RFID or DSRC and vehicles classification system. However, extending operation range, reducing sensibility to inclement weather as well as low cost and small size of Free-Flow ETC system are always challenging. This presentation reviews our works to enhance the performance of vehicle identification systems and to design a vehicles classification system by using electromagnetic waves Free-Flow ETC system. The State-of-Art vehicle identification and classification systems are presented and discussed. The first part of this presentation deals with improving performance of two vehicle identification systems: UHF RFID and DSRC. Five new antennas were realized which are high gain and easy to be industrialized. The second part is devoted to the study of a classification of different types of vehicles from the scattered waves captured by the system. Three methods of vehicle classification are proposed and tested in the road environment. Such/This system detects the presence of vehicle and measures the distance between vehicle and itself with a good accuracy. The principle of the system is based on Ultra-Wideband radar technology in which transmitting signal with a very short duration pulse is used. The future researches related to this direction are also defined.

Multimodal indoor localization using heterogenous technologies
Department PSI - MICA


Many user localization technologies and methods have been proposed for either indoor or outdoor environments. Among the most used technologies are GPS, RFID, others methods based on WiFi, camera, accelerometer, microphones, etc. However, each technology has its own backwards, for example GPS is not good with indoor localization when number of visible satellites is reduced cause of walls blocking; WiFi positioning is only suitable for user localization with low precision because of its accuracy varying from few meters to tens of meters; RFID, a proximity scheme, is limited in a small range since RFID readers could not be installed at every location. Recently, many researches and designs have been proposed to build a combination of multiple localization technologies system which can provide higher precision results and solve the limitation in each localization technology alone. Pfeifer proposed a design to extract results from localization technologies as useful information in real time, however it lacks ideas and algorithms about how those results should be fused and analysed to produce better results. Few systems already combined some localization technologies, which showed to improve in precision, but these systems depend on specific technologies and lack of availability characteristics: GPS, WiFi, Zigbee; RFID, WiFi, camera; WiFi, step count. In this paper, a general approach to multimodal localization system combining multiple technologies based on the idea of dividing spaces into grid points where location result will be chosen as the point with highest probability depends on a given precision is proposed. The system does not depend on any specific localization technologies but is built to be an open platform so that multiple heterogeneous localization technologies can be integrated, since more technologies applied means we have more information to improve precision as well as availableness.
