Abstract
In Long Term Evolution (LTE) networks, centroid topology optimization (CTO)-based schemes have been widely used to construct network topologies such that overall network performance is improved. In this paper, we systematically analyze CTO-based schemes and develop new schemes to improve network performance by reconnecting disconnected devices. First, we conduct an investigation of CTO-based schemes to understand their limitations. Then, we propose two schemes, called the Power Control-based scheme and Femto Relaybased scheme, to overcome this limitation in LTE networks, in which CTO-based schemes are implemented. Via intensive performance evaluation using NS3, we validate the effectiveness of our proposed schemes towards addressing the limitations of CTO-based schemes. Our results demonstrate an improvement in LTEnetwork performance above both the unoptimized and CTO-based schemes with respect to throughput, delay, delay standard deviation (DSD), etc.
