Resource Allocation Scheme to Support QoS in Mobile Multimedia Networks

Abstract

The macrocell-femtocell overlaid system is a promising means by which to extend coverage and to support higher data rates for mobile multimedia services. This paper proposes a resource allocation mechanism to enhance service continuity in a Long Term Evolution Advanced system. In order to support service continuity in real-time services, it performs load control to satisfy maximal data throughput. Moreover, it considers the QoS requirements of real-time and non-real-time services, such as voice, video streaming, and data. Simulation results show that our scheme provides better performance than a conventional one with respect to outage probability and data transmission throughput.
