Les Réseaux de Capteurs Sans-Fil (RCSF) sont des types spéciaux de réseau ad-hoc. Ils sont constitués d’un grand nombre de nœuds (capteurs sans-fil), capables de récolter et de transmettre des données environnementales de manière autonome. La position de ces nœuds n'est pas obligatoirement prédéterminée. Ils peuvent être aléatoirement dispersés dans une zone géographique, appelée « champ de captage » correspondant au terrain d'intérêt pour le phénomène capté. Les RCSF ont plusieurs domaines d’applications (militaires, médicales, environnementales, commerciales etc…). Ces réseaux sont apparus avec de nombreux défis à relever notamment les problèmes de routages, de couvertures, de gestion d’énergie et bien d’autres.
