Abstract
In the communication scheme for Internet of Things (IoT) systems, reliability and low power are essential in ensuring the connection of a large lot of terminals. Multi-Hop based cooperative communication is a promising tool towards achieving that goals. Moreover, in many works of research, the channel fading is limited to multi-paths fading modeled by Rayleigh or Nakagami-m distributions, or a combination of the two with pathloss fading. In this paper, we have explored the Generalized K fading which offers a more general distribution encompassing multi-paths fading, pathloss fading and shadowing. Thus, we investigate the Decode and Forward relaying strategy over Generalized K channels for multi-hops IoT networks. We derive analytical expressions of the average symbol error probability and the outage probability. Finally, we show the validity of the theoretical results by simulation.
