The fairness of resource allocation and its impact on the 5G ultra-dense cellular network performance

This paper proposes novel insight that the performance of a network depends on the Resource Allocation Fairness level. In the observed network, 5G Ultra Dense Cellular Network with a single gateway, a macro cell consists of dozens of ENBs (Enode B) and a single gateway. When there is large variation in the traffic of each ENB in a macro cell there will be high performance loss. In order to maintain the network performance, a new formula to calculate an index which is called Harmony-in-Gradation Index is proposed. The index plays important role in determining the network performance. The main idea of resource allocation method with implementing the new formula is to maintain the ratio of an ENB traffic to its backhaul link capacity allocated by the gateway of each ENB in a macro cell to have a value that is in proximity to each other. This method is believed to be able to maintain a good network performance.
