An Approach to Energy Efficiency in a Multi-Hop Network Control System through a Trade-Off between H-inf Norm and Global Number of Transmissions

The present work proposes a new approach to energy effiency for filtering of a system interconnected by a Multi-Hop network. The minimization of the energy cost per time unit is obtained through limiting the number of packets retransmission in the Hop-by-Hop mechanism. We explore a trade-Off between system performance, measured by estimation error H-inf norm and energy consumption. The proposal is validated using a theoretical model for energy consumption of MICA2 transceivers.
