QoS Provisioning in a Cellular Network from a Multifaceted Perspective

Abstract

Most of the cellular network environments are aimed at cost minimization in such a way that either of uplink or downlink Quality of Service (QoS) are adhered. Although it is commercially more viable, however, these networks are not the right answer to the call of emergency situations and tactical scenarios. The reason is that when the dual QoS perspective of uplink and downlink is considered simultaneously, it becomes increasingly dicult to manage both these aspects owing to the associated computational complexity. In this work, we consider the case of dual QoS provisioning in a cellular network with regards to throughput when renewable energy sources are kept at base station (BS) disposal. Moreover, we opine that the residual energy of mobile terminal is critical factor in case of uplink, and dene an upper bound on its outage probability. With an aim of cost minimization, we devise two schemes to separately address the BS operation and energy harvesting for dual QoS provisioning, and validate our approach with simulation results
