Estimation of the Energy Consumption of Mobile Sensors in WSN Environmental Monitoring Applications

The increasing necessity to have wireless sensor nodes capable to be active for a long time without battery recharge asks for technologies and methods that can anticipate the level of energy drain in these devices. In this paper a modelling approach based on Fluid Stochastic Petri Nets is proposed. The main contribution of the paper is the definition of a model to estimate single node performance in presence of several energy consuming entities. The definition of this single node model is relevant in order to properly support the design of more complex network topologies. The paper also reports first experimental results on model analysis mainly conducted by simulation.
