This paper studies an Internet-of-Things (IoT) network employing areconfigurable intelligent surface (RIS) over generalized fading channels.Inspired by the promising potential of RIS-based transmission, we investigate aRIS-enabled IoT network with the source node employing a RIS-based accesspoint. The system is modelled with reference to a receiver transmitter pair andthe Fisher-Snedecor F model is adopted to analyse the composite fading andshadowing channel. Closed-form expressions are derived for the system withregards to the average capacity, average bit error rate (BER) and outageprobability. Monte-Carlo simulations are provided throughout to validate theresults. The results investigated and reported in this study extend earlyresults reported in the emerging literature on RIS-enabled technologies andprovides a framework for the evaluation of a basic RIS-enabled IoT network overthe most common multipath fading channels. The results indicate the clearbenefit of employing a RIS-enabled access point, as well as the versatility ofthe derived expressions in analysing the effects of fading and shadowing on thenetwork. The results further demonstrate that for a RIS-enabled IoT network,there is the need to balance between the cost and benefit of increasing the RIScells against other parameters such as increasing transmit power, especially atlow SNR and/or high to moderate fading/shadowing severity.
