Impact of Transmission Power Control in multi-hop networks [PDF]

open access: yesFuture generations computer systems, 2017
Many Transmission Power Control (TPC) algorithms have been proposed in the past, yet the conditions under which they are evaluated do not always reflect typical Internet-of-Things (IoT) scenarios. IoT networks consist of several source nodes transmitting
