The performance of the multi-hop relaying networks applied to Internet of Things (IoT) networks is investigated in the present work. To ameliorate the reliability of the whole network, for each hop, we employ cooperative communications subject to co-channel interference. In particular, several cooperative schemes are applied in the present work namely, incremental relaying, selection combining, and maximal ratio combining. In this context, we derive the exact closed-form expressions of end-to-end (e2e) outage probability (OP) of the whole systems over Rayleigh fading distribution. Numerical results based on the Monte-Carlo method are then employed to not only confirm the accuracy of the proposed mathematical framework but also to illustrate the advantages of the considered schemes compared with the conventional multi-hop relaying without using cooperative communications.
