In this paper, we address the problem of how to make the wireless service provider have better profits with consideration of user experience provision in wireless video broadcasting systems. We propose a marginal-based pricing and a resource-allocation framework to achieve better resource utilization and profit improvement. The marginal principle includes 1) marginal user principle, in which a pricing...
In this paper, a joint channel-and-queue-aware relay selection and resource allocation scheme at the scheduling phase in an OFDMA downlink cellular network is proposed. The scheme can choose the best relay to cooperate and allocate subchannels and power for the source and the relay for the selected packet which can maximize the proposed utility function waiting in the base station. Under the premise...
Recently, the fast development of communication technologies brings a heterogeneous network environment, which provides diverse services for users. Resource management and allocation is crucial and complicated for the assurance of end to end quality of service (QoS), which is especially difficult in heterogeneous networks. Therefore, an open resource allocation architecture is important for the service...
With the proliferation of wireless multimedia applications, multicast/broadcast has been recognized as an efficient technique to transmit a large volume of data to multiple mobile stations at the same time. In most multicast systems, the transmitter (e.g. base station) adapts its data rate to the furthest located users, so as to guarantee service quality to as many users as possible. Predictably,...
