 This work is especially useful for battery-powered wireless sensor nodes in QoS-constrained applications and offers a solid framework for network design and performance analysis of heterogeneous multi-hop wireless industrial networks.
<meaning-changed>  This work is especially useful for battery-powered wireless sensor nodes in QoS-constrained applications and offers a solid framework for network design and performance analysis of heterogeneous multi-hop wireless industrial networks.
 Moreover, we show, using extensive simulation study, that the proposed bound-based power allocation performs reasonably well compared to the real optimum, especially in the case of WirelessHART networks.
