A fundamental trade-off lies between the average queueing delay and the power consumption when transmitting stochastically arriving data over a fading channel. Providing real-time services on low-energy-supply and low-complexity devices has attracted much attention from both academia and industry, for its extensive use in transportation, manufacturing, living, and so on. In this paper, we investigate...
Joint channel-aware and buffer-aware scheduling along with rate/power adaptation is a promising solution to assure Quality of Service (QoS) and improve energy efficiency. In this paper, an analytical delay-power tradeoff and optimal threshold-based scheduling are proposed. In particular, we are interested in the scheduling policies where the scheduler only needs to decide transmitting or not. More...
Owing to the capability of accumulating mutual information from the transmission of previous nodes, rateless codes can boost the network performance considerably, and hence have sparked much interest recently. However, how to efficiently schedule multi-hop multi-relay transmissions with the aid of rateless codes remains a challenging work. Particularly, it requires high complexity to find an optimal...
