Abstract:

This document studies the influence of the features of the propagation scenario in the performance of energyefficient routing algorithms for wireless sensor networks (WSN). Although there are a lot of works regarding energyefficient routing protocols, almost no reference to realistic propagation channel models and their influence is made in the literature. Considering that the propagation channel may affect the efficiency of the different energy-efficient routing algorithms, different propagation scenarios are studied in this work, from the most simplistic free-space propagation model to more complex ones. The latter includes the effects of multipath propagation, shadowing, fading, etc. In addition, spatial diversity transmission/reception models are considered to mitigate the effects of hard propagation fading.
