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
For designers of wireless networked control systems, this offers a trade-off approach to reduce energy consumption while maintaining acceptable estimation error.
This work proposes a method to improve energy efficiency in multi-hop networked control systems by limiting packet retransmissions, balancing H-inf norm performance with energy consumption. Validation using MICA2 transceiver models shows reduced energy use.
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.
