Performance Evaluation of Resource Management Mechanisms in LTE-Advanced Networks

Abstract

Recently, D2D (Device-to-Device) communication and MTC (Machine-Type Communication) in LTE-Advanced networks have become a promising technologies. In D2D communication, interference between cellular and D2D links should be controlled while guaranteeing QoS (Quality-of-Service) of communication service. In MTC, network congestion due to the mass concurrent access requests generated by MTC devices should be controlled while guaranteeing QoS of traditional cellular communication. In this paper, we provide an overview of resource management mechanisms for D2D communication and MTC. Besides, we investigate the performance of a typical mechanism of congestion control for MTC. EAB (Extended Access Barring) mechanism barring the radio access of the devices according to the their ACs (Access Classes) releases the overload and congestion of RA (Random Access) channel temporarily.
