Performance Analysis of Local Anchor Based 5g Hetnets Using Stochastic Geometry

In heterogeneous 5G networks (HetNets) a local anchor node ensures coordination among small cell low power nodes (LPNs). User equipment (UE) that cannot directly reach the local anchor node will transmit and receive data through LPN. To facilitate measurement of the interference power for this 2-hop hierarchical network topology, a total distance distribution between a UE and a local anchor is derived as a closed form expression in terms of hypergeometric functions. This distribution can be directly utilized in the interference power and outage probability analysis. Numerical results show that the interference power can be tightly approximated using the derived distribution for large distances, which significantly eases the outage probability analysis.
