Abstract

The utility optimization problem of radio access network-slicing aided mobile systems is formulated considering both throughput and delay demands from a mobile network operator's perspective, whilst relying on stochastic geometry and Lyapunov optimization. Then a joint virtual resource optimization algorithm is proposed to dynamically allocate both virtual spectral and the power resources. Our numerical results support both the high-throughput slice and the low-delay slice and quantify the associated throughput vs. delay trade-off. Moreover, we compare the proposed algorithm with the benchmark one, which ensures better utility.
