Cloud computing, a new thing which is only three years old, becomes the most fashionable technology and developing trend in IT industry now. People say “X as a service” in the cloud computing, which means that everything including software and hardware can be taken as a service for consumers in the cloud. Meanwhile, a high quality multimedia(More)
In this paper, we propose an adaptive user scheduling and resource management algorithm for multiuser MIMO downlink systems with heterogeneous delay requirements, in order to not only maximize the system throughput but also maintain delay constraints as well. We adopt the concepts of effective capacity and effective bandwidth to illustrate the behaviors of(More)
One fundamental issue in supporting multi-cell ultrahigh throughput wireless local area networks (WLAN) is how to coordinate inter-cell interference. In this paper, we present a novel max-min fair resource allocation scheme to increase system capacity and improve the communication quality of cell-edge users. We assume the users within one cell operate on(More)
In this paper, we study delay-aware resource control in device-to-device underlay communication systems with multiple source-destination pairs. With the consideration of random bursty arrivals and delay-sensitive information flows, crosslayer optimization seeks to develop algorithms that (i) provide efficient throughput-utility, (ii) are robust to general(More)
In this paper, a resource allocation algorithm is proposed for different quality of service (QoS) guarantee, fair transmission and high data rate in orthogonal frequency division multiple access (OFDMA) and wireless local area network (WLAN) integrated system. First, different QoS requirements are converted into different rate requests for simplifying the(More)
Software-defined sensor networks (SDSN) has appeared as a new networking paradigm that allows centralized management and control of networking devices programmably to increase network reliability. In this paper, we propose a joint routing and resource management algorithm that maximizes the system throughput for SDSN. We show that the formulated(More)
Introducing Peer-to-Peer (P2P) technology into IP Multimedia Subsystem (IMS) is hard but important, especially to the streaming media service. Based on the strength analysis of IMS and P2P, three solutions with the features of signaling centralized and media distributed are compared, and eventually the solution of managing P2P via application server is(More)
