Context

.

NeCS

is a joint CNRS (GIPSA-lab)-INRIA team. The team goal is to develop a new control

framework for assessing problems raised by the consideration of new technological low-cost and wireless

components, the increase of systems complexity and the distributed and dynamic location of sensors

(sensor networks) and actuators. The team is a bi-located at INRIA (Montbonnot) and at the GIPSA-lab (at

the Grenoble campus). This position will be funded by the EU

FeedNetBack

STREP project in the

Networked embedded and control systems area. The project addressed innovative problems of control co-

design issues in control/communication/computation and energy management in applications of control

through WSN.

Topic description.

Wireless low-cost sensor networks is an expanded technology in many new and varied

areas such as: traffic monitoring and control, undersea monitoring/exploration, environment sensing,

building services, etc. In this context, future generation of this type of sensors is expected to be packaged

together with communication protocols, RF electronics, and energy management systems. The

development of such integrated sensors will be driven by constraints like: low cost, ease of replacement,

low energy consumption, and energy-efficient communication links. The objective of this thesis is to study,

from different points of views, the problem of saving a maximum of energy at the sensor level (to maximize

the battery life-time), but also at the nodes. Issues of energy-efficient coding, and power control at each

sensor will be considered. In this context the main different with standard existing approaches for energy-

saving in SWN is that the coded information need to trade stability/precision of the closed-loop, with the

amount of energy used for the data transmission. Entropy coding was proposed in our previous work [1, 2]

as a good alternative to save mean energy consumption while coding the information.

From the other

hand, efficiency handling of power control is also an additional degree of freedom to cope with lost and

collision of packages leading to transmission delays and lost of information [3].

This items form part of the

WP3 of the EU project FeedNetBAck mentioned before.

Requested Work

. The doctoral work will focus on the development of

analysis, and constructive control

design methodologies accounting with the energy-aware behavior mentioned above.

The student will

participate to project meetings (FeedNetBack), stays, visits, and elaboration of deliverables concerning this

project.

Candidate profile

. Applicants should have an Engineering degree with a specialization in Control

Theory, with if possible a good knowledge in Wireless transmission and networks. Application should be

send electronically with and a CV including the school and last year university ranking. Applicants not filling

this requirement will not be considered.
