Abstract

A network with a multidirectional relay is used in a wireless sensor network so that nodes can exchange their information with each other more efficiently. It assumes three distinct transmission strategies previously defined. They differ in the way the nodes transmit, one is in pairs, the other is all together and in the third half transmits simultaneously. An analysis of the energy efficiency of these strategies was carried out. The one where all the nodes transmit together had the best energy efficiency when the maximum effective rate was considered. By relaxing this condition, the others proved to be more efficient.
