Mobile edge computing (MEC) provides a promising way to bring enhanced computing capabilities in proximity to user equipments (UEs). Various previous works have been done and they usually focus on how to segment the computation intensive task and how to offload the task to edge of the network with plenty of computation capacity. However, few of them consider integrating MEC with small cell networks...
In the area of full duplex (FD)-enabled small cell networks, limited works have been done on consideration of cache and mobile edge communication (MEC). In this paper, a virtual FD-enabled small cell network with cache and MEC is investigated for two heterogeneous services, high-data-rate service and computation-sensitive service. In our proposed scheme, content caching and FD communication are closely...
The integration of both fronthaul and backhaul into a single transport network (namely, 5G-Crosshaul) is envisioned for the future 5G transport networks. This requires a fully integrated and unified management of the fronthaul and backhaul resources in a cost-efficient, scalable and flexible way through the deployment of an SDN/NFV control framework. This paper presents the designed 5G-Crosshaul architecture,...
An implementable blood glucose estimation in computer is presented. In general, the existing effective approaches for measuring the blood glucose concentration are mainly based on blood test, which is painful for patient. Painless methods to obtain blood glucose concentration will dramatically improve the case. As one of the painless methods, this paper implements the blood glucose estimation with...
Massive connectivity is one of the main requirements of the fifth generation (5G) multiple access, and sparse code multiple access (SCMA) as a new non-orthogonal multiple access technique in frequency domain will probably meet the requirement. The sparsity of codewords is the key feature of SCMA, which can enable codewords to be overloaded. In this paper, we evaluate the performance of overloading...
This paper describes the development and implementation of a cloud computing-based remote collaborative system for performing practices in basic IT software engineering courses. In cloud computing environment, the features of remote collaborative engineering practices is not only the abundant resources sharing. The development of virtual laboratory provides users virtual software development environment...
In this paper, we propose a boosting based tracking framework using transfer learning. To deal with complex appearance variations, the proposed tracking framework tries to utilize discriminative information from previous frames to conduct the tracking task in the current frame, and thus transfers some prior knowledge from the previous source data domain to the current target data domain, resulting...
Though P2P grid has attracted great attention these days, trust management is still a complex and difficult task. This paper proposes a dynamic reputation management framework to enhance trust in the unstructured P2P Grid. The proposed model extends the normal trust model and takes the impact of the mobility of peers into account. Based on this framework, we show how to calculate, store, collect and...
Although some reputation schemes have been proposed for ad hoc networks, they are still not the most suitable for WMNs due to the special infrastructure and communication mode in WMNs. In this paper, a hierarchical reputation management framework for WMNs is presented. We show how to collect and query reputation values in an accurate, secure and efficient manner. The correlation validation algorithm...
Scene is the semantic unit in video. Video scene segmentation is a difficult task in content based video structure analysis. This paper proposes a new approach for scene boundary detection. We first construct shot content coherence signal using normalized cut criterion and then use a heuristic algorithm to detect scene boundary. Because the normalized cut criterion simultaneously emphasizes on the...
In a service-oriented grid environment, how to discover the desired service easily and well is a prime concern since the service providers are selfish and owned by different organization. In this paper, we suggest a reputation based mechanism to implement service selection in the service-oriented grid. The working model and functionality offered by the proposed reputation service are discussed. We...
In grid environments, advance reservation mechanism is to provide reliable resource co-allocation and scheduling for applications. However, excessive advance reservation will bring about many negative effects for system's performance, such as lower resource utilization and higher rejection rate. To mitigate these negative effects of advance reservation, a relaxed reservation strategy is proposed,...
