 Our numerical study shows an overall transmit power savings of up to 95\% when compared to a fixed power allocation . We also apply our algorithm to a realistic WirelessHART network setup and observe that link heterogeneity can significantly influence network lifetime when no efficient power management is applied.

 Our numerical study shows an overall transmit power savings of up to 95\% when compared to a fixed power allocation scheme when using a service model in terms of the Shannon capacity limit. For a more realistic set-up, we evaluate the performance of the suggested algorithm in a WirelessHART network, which is a widely used communication standard for process automation and other industrial applications. We find that link heterogeneity can significantly influence network lifetime when no efficient power management is applied.
