In this paper, we suggest a novel multi-GPU scheme that can provide flexible interconnections between multi-GPUs and displays with no additional hardware by implementing new software features, while avoiding system overhead. Our proposed scheme offers the complete concept of windowing system and GPU driver for single-node multi-GPU system on multiple display environments.
A large number of corporations are jointly developing various Cloud platforms. However, problems have occurred in resource management due to multiple number of platforms that were not integrated at the time of development of the Cloud federation service. If user uses heterogeneous platform, there arises difficulty in resources management. Therefore, there is a need to develop a federation monitoring...
Recently, OpenFlow and FlowVisor are the most promising architecture components of the software-defined networks (SDNs). The evolution of these components brought the revolution of utilizing network elements for the shared and virtual network infrastructure, however from the aspects of production networks, it still lacks of some key component. For example, policy-based services provisioning for user-defined...
Coarse-grained reconfigurable architecture (CGRA)-based multi-core architecture aims at achieving high performance by kernel level parallelism (KLP). However, the existing CGRA-based multi-core architectures suffer from much energy and performance bottleneck when trying to exploit the KLP because of poor resource utilization caused by insufficient flexibility. In this work, we propose a new ring-based...
In this paper, we propose an inter-cell interference management scheme using a multi-cell SRN (Shared Relay Node) in order to avoid inter-cell interference and to increase the cell throughput in 3GPP LTE (3rd Generation Partnership Project Long Term Evolution)-Advanced networks. Recently, the CoMP (Coordinated Multi-Point transmission/reception) scheme has received growing attention as a promising...
A simultaneous multithreading multicore processor is proposed to accelerate object recognition for 720p HD video streams. The multithreading architecture with Q-learning based dynamic resource management enables concurrent processing of 8 region-of-interests with 5-stage fine grained recognition pipeline outperforming previous object recognition processors with 342GOPS computing power. In addition,...
In this paper, we propose a hybrid division cooperative transmission (HDCT) scheme for system throughput enhancement in enterprise femtocell systems. In HDCT scheme, a cooperative transmission (CT) scheme is applied to user equipments (UEs) located at the edge of a serving femtocell base station (fBS), whereas conventional scheme is applied to UEs located near the fBS. In the zone where CT is applied,...
An inter-cell interference (ICI) problem between co-channel BSs has been one of main challenging research issues in downlink cellular networks. Fractional frequency reuse (FFR) and BS cooperation are useful techniques to manage the ICI problem. By combining the BS cooperation and FFR techniques, we propose to determine an efficient cooperation mode and the type of subchannels, i.e., reusable subchannels...
Service discovery (SD) protocols in Wireless Sensor Networks (WSNs) enable the sensor nodes to locate services offered by other nodes in the same or any other network and invoke the services. But it is a crucial task for sensors to perform timely service discovery in a pervasive environment. Also ongoing research in this field is limited with only few SD protocols proposed for some specific use cases...
This paper investigates the comparison of two different channelization schemes of relay links in the relay aided cellular network for different transmit power and the number of relays. One is the orthogonal relay subchannel allocation (ORRSA) which assigns each relay links to mobiles with orthogonal subchannels, leading to no interference between relays in the same cell. The other is the overlapped...
Cloud computing has recently paid attention as a way to share the resources to provide scalable and on-demand services. Across various authorities, cloud resources should be configured to a virtual organization (VO) according to user's requirements. Ontology-based representation of cloud computing environment would be able to conceptualize common attributes among cloud resources and to represent semantic...
