Networking unattended sensors is expected to have a significant impact on the efficiency of many military and civil applications. Sensors in such systems are typically disposable and expected to last until their energy drains. Therefore, energy is a very scarce resource for such sensor systems and has to be managed wisely in order to extend the life of the sensors for the duration of a particular mission. In this paper, we present a new protocol of routing for wireless sensor networks named EERP (Energy-Efficient Routing Protocol for wireless sensor networks) that maximizes the lifetime of the sensors. Its principle is as follows: each node sends the data captured on the way which minimizes the consumption of energy as well as the variance of energies consumed by the sensors nodes. Our experimental results show that our protocol increase the lifetime of the sensors network and conserve the energy of the nodes up to optimum level better than the Energy Aware Routing protocol (EAR).
