L'énergie Dans Les Réseaux De Capteurs Sans Fil
Résumé: A sensor/micro sensor network is a cooperating set of sensor nodes using wireless communications as part of an ad-hoc network. Each node comprises a sensor making it possible to observe a phenomenon occurring nearby. This micro-sensor technology has opened up new and varied application perspectives in many fields (military, home automation, environmental, etc.). However, its exploitation remains difficult and poses many problems. The challenges are at the algorithmic level, localization, deployment, data collection/fusion, as well as coverage and reducing power consumption to maximize network lifetime. Indeed, the only energy source of a sensor node is its battery with a determined lifespan. And the network must perform its functions with the amount of energy it has without the intervention of the operator who deployed it. In this context, the objective of this work is to study the energy problem in the wireless sensor network.
