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...
We consider the resource allocation problem in a structured sensor network. While new technologies are making sensors smarter, smaller, and cheaper, an emerging problem is how to allocate limited energy, radio bandwidth, and other resources to achieve efficient global behavior for high performance, QoS, and long network lifetime. Conventionally, resource allocation is treated as an optimization problem...
