Abstract

The use of wireless sensor networks has been increased substantially. One of the main inconveniences of this kind of networks is the energy efficiency; for this reason, there are some works trying to solve it. Traditionally, these networks were only composed by sensors, but now auxiliary elements called routers have been included to facilitate communications and reduce energy consumption. In this work, we have studied the inclusion of routers in a previously established traditional wireless sensor network in order to increase its energy efficiency, optimizing lifetime and average energy effort. For this purpose, we have used two multi-objective evolutionary algorithms: NSGA-II and SPEA-2. We have done experiments over various sceneries, checking by means of statically techniques that SPEA-2 offers better results for more complex instances.
