While adopting an approach of innovation diffusion in terms of interacting agents, we emphasise the role of cumulated influence in the context of social networks. We first introduce a cumulative effect in the classical epidemic model which involves a slower starting phase followed by a more pronounced acceleration phase. We then show that the topology of the network affects both equilibrium selection as well the pace of diffusion. Hence the nature of uncertainty characterising the diffusion process is affected by the structure of the network and the distribution of initial adopters.En nous situant dans le cadre des modèles interactionnistes de diffusion de l'innovation, nous mettons en évidence le rôle joué par la notion de cumul d'influenc...
