This SpringerBrief presents radio resource allocation schemes for
buffer-aided communications systems over fading channels under
statistical delay constraints in terms of upper-bounded average
delay or delay-outage probability. This Brief starts by considering
a source-destination communications link with data arriving at the
source transmission buffer. The first scenario, the joint optimal
data admission control and power allocation problem for throughput
maximization is considered, where the source is assumed to have a
maximum power and an average delay constraints. The second
scenario, optimal power allocation problems for energy harvesting
(EH) communications systems under average delay or delay-outage
constraints are explored, where the EH source harvests random
amounts of energy from renewable energy sources, and stores the
harvested energy in a battery during data transmission. Online
resource allocation algorithms are developed when the statistical
knowledge of the random channel fading, data arrivals, EH processes
governing the system dynamics is unknown a-priori. This Brief
continues with a source-relay-destination communications link with
buffers available at both source and relay, as part of a multi-hop
network. Optimal resource allocation schemes for this 3-node
relaying system to maximize its effective capacity under a
delay-outage constraint are proposed, with special emphasis on
relay roles: Half-duplex (HD) or full-duplex (FD) relay operation.
With HD relay, the adaptive link selection relaying problem jointly
with both fixed and adaptive power allocation schemes is
investigated. Within each transmission frame, either the
source-relay link or the relay-destination link is selected to be
active depending on the channel conditions. With FD relay under the
presence of non-zero residual self-interference (SI). This Brief
also presents source and relay power allocation schemes for both
cases of available knowledge of the channel state information at
transmitter (CSIT): instantaneous or statistical. Professional and
researchers working in this related field and advanced-level
students in electrical or computer engineering will find the
content valuable as a reference.
