The selection of active units is an essential task for sensor networks because it allows to increase the service life of the networks while guaranteeing coverage. In this paper, we propose a fully distributed method for active units selection that automatically adapts to sensors extinction without activating unnecessary idle units. This method relies on both of the use of homology and the discrete...
The homology groups provide useful information about a space. In several applications, including sensor networks, a combinatorial space is built to reflect the data and their relations about a specific topic to be analyzed. Hence the computation of the homology groups is of prime interest. However, the combinatorial space may vary and the computation of its homology groups becomes more difficult....
