A new fairness index and novel approach for QoS-aware resource allocation in LTE networks based on utility functions

Abstract

In this paper, a new fairness index to measure resource allocation performance for real-time/delay-tolerant applications is introduced. This index can suggest a new approach for resource allocation. There are several methods have been previously introduced in the literature for resource allocation in cellular networks. Fairness index have an important role to evaluate the performance of these methods. Here, we focus on utility function based resources allocation and related algorithms. According to the introduced method, the base station (BS) allocates resources based on different services requirements. Because of using the appropriate utility function for each application, the requested quality-of-services (QoS) are satisfied. The new well-defined fairness index shows that the proposed method has a good performance for different real-time/delay-tolerant applications. Additionally, numerical results show that this approach is able to improve other important indicators such as throughput and mean opinion score (MOS) as well. © 2015 IEEE.
