Energy limitation of a sensor network is a very important feature which distinguishes it from traditional networks and a number of methods to saving energy consumption have been studied in sensor networks. Most of those works have focused on Network, MAC or PHY layer and the lifetime of a sensor network cannot be pre-determined. But some sensor network might be able to survive for some specified time. In this work, we propose an energy consumption scheduling model, at application level of a node, that ensures predetermined lifetime. To do this, first, we divide applications into six classes and define five operations of an application. Second, an energy consumption model is proposed using those five operations and consumption energies of each operation are calculated by a statistical method. Finally, energy consumption schedules of each application are rebuilt for a node to survive for predetermined lifetime, e.g. varying the period of response and sensing and the number of actuation, etc. Consequently, it is ensured for nodes to survive for the pre-determined lifetime.
