Energy-aware routing in wireless ad hoc and sensor networks
Saoucène Mahfoudh, Pascale Minet · 2010
In this paper, we consider wireless ad hoc and sensor networks where energy matters. Our contribution deals with energy efficient routing. The idea consists in reducing the energy spent in the transmission of a packet from its source to its destination, while avoiding nodes with low residual energy. The solution we propose, called EOLSR, is based on the link state OLSR routing protocol. It comprises an energy model and three algorithms: selection of energy aware multipoint relays, computation of energy efficient routes and optimized broadcasts. All the design choices made for these algorithms have been validated by simulations. Moreover, EOLSR outperforms the solution that selects routes minimizing the end-to-end energy consumption, as well as the solution that builds routes based on node residual energy.
