The kappa-mu fading model is an advanced channel model in super dense wireless networks. In this paper, we evaluate the performance of the system over kappa-mu fading channel in super dense relay networks with consideration of multiple independent but not necessarily identically distributed (i.n.i d.) co-channel interference (CCI) under interferencelimited environment. More specifically, we derive a useful and accurate cumulative distribution CDF) expression of the end-to-end signal-to-interference plus noise (SINR) ratio. Moreover, we derive novel analytical expressions of the outage probability (OP), average bit error probability (ABEP) and average capacity for binary modulation types and arbitrary positive values of kappa-and mu of such system. Furthermore, we propose asymptotic analysis for both the OP and ABEP to give physical insights. A simplified analytical form for the ABEP at high-SNR regimes is provided as well. Finally, the accuracy of the derived expressions is well validated by Monte Carlo simulations.
