Heterogeneous system consists of a node with low power including femto cells, relays and base stations. Heterogeneous network results in a interference between its network elements and hence makes the communication channel more complex and challenging for analysis. Successive interference cancellation (SIC) is a promising technology which helps in improving the efficiency of wireless networks. SIC continuously decodes and cancels out the interfering signal which are stronger, until it decodes the desired signal. The impact of SIC is analyzed on a multi-tier heterogeneous network consisting of cellular users, device-to-device (D2D) users, relay nodes and base stations. A stochastic equivalence model is derived to analyse the outage probability and success transmission probability for a multi-tier heterogeneous network (mHetNets). The successful transmission probability and outage probability using SIC technique is analysed for multi-tier and D2D tier (single-tier) network varying the SIC level and nth strongest interferers. Similarly, the successful transmission and outage probability is analysed for multi-tier and single tier varying the (SIRT) for device-to-device receivers and access points. The number of cancellations of nth strongest interferer is varied and transmission probability is analyzed. The probability of successful transmission is increased with an increase in cancellation of n interferers. The results for probability of successful transmission is 0.5 for multi-tiers, when the number of cancelled interferer n = 1. It reaches to 0.95 for n = 9. Outage probability is lower for higher value of n and is increased with an increase in SIRT.
