This paper considers the BBU computing resource allocation problem in a C-RAN system. In particular, we consider the additional computing resource consumption introduced for coordination between different BBUs when the tasks of a cell is processed by different BBUs and consider load balancing among multiple BBUs in order to reduce the effect of a breakdown BBU on the system. The problem is formulated...
As the rapid development of Electric Vehicles (EV), how to strategically deploy charging stations becomes an emerging and challenging question to EV communities. However, the cease operation of charging stations and the consequent impacts have been discussed little. In this paper, by analyzing a large scale electric taxi GPS data, we make the first attempt to investigate this problem. A case in Shenzhen...
With the rapid development of database and web technology, the way data organized and presented is becoming increasingly complicated while data sources are also intermingled with inaccurate information. Therefore, studies in truth discovery becomes overwhelmingly significant for it is critical for netizens to identify sources of high quality as well as to select the most accurate information from...
Synthetic Aperture Radar (SAR) has been widely used in airborne remote sensing and satellite ocean observation fields to reduce the affect of weather condition and sun illumination. As technology developed, swath and resolution requirements are increased in terrain, which result in a huge increase in echo data and simulated time[1]. With the development of graphics processing unit (GPU), it can reduce...
In this paper, we consider the problem of cross-layer radio resource management in heterogeneous networks (HetNets) with flexible backhaul, which aims at minimizing the total transmit power of base stations (BSs) while guaranteeing the average end-to-end data rate requirement of each data flow. We formulate the problem as a two-timescale stochastic optimisation, where the long-timescale control variables...
The requirement of distributed computing of all-to-all comparison (ATAC) problems in heterogeneous systems is increasingly important in various domains. Though Hadoop-based solutions are widely used, they are inefficient for the ATAC pattern, which is fundamentally different from the MapReduce pattern for which Hadoop is designed. They exhibit poor data locality and unbalanced allocation of comparison...
One of the main advantages of utilizing flexible backhaul in future HetNets is that it can provide better user experience through flexible resource allocation. For this purpose, it is important to provide the required quality of service (QoS) in such networks. In this paper, we consider the problem of cross-layer radio resource management in HetNets with flexible backhaul which guarantees minimum...
The main challenge of wireless video multicast is to support receivers' heterogeneous characteristics and realize graceful degradation of video quality. The newly emerged Softcast provides smooth video quality for wireless multicast based on raw orthogonal frequency division multiplexing (OFDM) over additive white Gaussian noise (AWGN) channels but its performance suffers when transmitted over practical...
In this paper, we focus on the problem of hierarchical cross- layer dynamic resource allocation for heterogeneous networks with flexible backhaul. We formulate the radio resource management problem as a two timescale non-convex stochastic optimisation problem which jointly optimizes flow control, routing control, interference mitigation and link scheduling in order to maximize a generic network utility...
This paper considers the joint power allocation and subcarrier pairing problem in decode-and-forward (DF) relaying orthogonal-frequency-division multiplexing (OFDM) system, and proposes a strategy, called MW-RA, to maximize the weighted sum rate with total power constraint. MW-RA is formulated as a mixed integer programming problem and then transformed to a convex optimization problem by continuous...
In order to meet the complicated requirements of jewelry enterprise resource management, the paper designed and implemented a distributed management information system. The system adopts a dynamic strategy to handle enterprise resources sharing both horizontally and vertically, including querying, adding, deleting and modifying jewelry information, gathering statistics information, scheduling production...
Virtual machines are allocated on demand in virtualized cloud platforms to provide flexible and reliable services. The major difficulty lies in satisfying the conflicting objectives of reducing response time while lowering resource costs. In this paper, a mathematical multi-tier framework for virtual machine allocation is proposed, which can be used to capture the performance of the cloud platform...
This article on platforms in the digital forest resource allocation and management processes. By now the grid environment to how to allocate resources in the research, the field of digital forestry accumulated a large number of the current standard treatment package into form Web services platform in the grid environment, workflow technology through these services effective series together, in order...
This paper studies how to design distributed resource allocation in multi-radio multi-channel wireless mesh networks with the objective of maximizing the network utility. We address the problem via a cross-layer approach with a joint consideration of multi-path routing, congestion control, scheduling, radio allocation and channel assignment. The problem is formulated as a mixed-integer non-linear...
