This study studies a multi-relay assisted Internet of Things (IoT) network within the context of mixed fading environments. Here, data transmission from the source to the destination is assisted through multiple decode-and-forward (DF)relays. In particular, this work revolves around mixed fading environments, characterized by the first-hop relaying links conforming to a uniform distribution while the second-hop relaying links exhibit Rayleigh fading. To enhance the overall efficacy of the network, we introduce two relay selection criteria. Specifically, the first criterion entails an optimal selection process hinging on the identification of the most proficient relay. This selection relies upon the channel parameters of dual-hop relaying links. In contrast, the second criterion adopts a sub-optimal selection approach by singling out the optimal relay solely based on the channel parameters of the second-hop relaying links. The performance evaluation of the two aforementioned relay selection criteria entails the derivation of analytical expressions governing the system outage probability. To validate the theoretical works presented in this research, we supplement our analysis with simulation results. Notably, our findings underscore the efficacy of augmenting network performance by augmenting the number of relays within the network topology, even in complicated mixed fading environments.
