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
