Power saving is a very challenging issue in wireless sensor networks. Many solutions are cited in the literature, which have significant contributions in energy conservation. The aim of this paper is to propose a distributed technique able to guarantee communications over all sensors and reducing in a considerable rate the energy consumed. The originality of the solution is the use fundamental principles inherited from distributed computing (leader election, consensus, and abstract ring structure). The aim is to allow to the network to achieve a self organizing procedure which assigns a slot time to each sensor. Indeed, each sensor will have a particular slot for listening and another one for sending.
