On the performance optimization for the cloud architecture with sleep-mode and registration service by Shunfu JIN, Haixing WU, Tiantian HUO, Wenjuan ZHAO

“…In order to balance the energy conservation and the service quality for anonymous users,a novel sleep-mode based architecture with the free cloud service and the registration cloud service was proposed.Regarding the free cloud service as the first service,the registration cloud service as the second service and the sleep sate as the vacation,a partial asynchronous multiple vacation queueing model with a second optional service was built.Applying the method of a matrix-geometric solution,the steady-state distribution of the queueing model was derived,and then the energy saving rate of system as well as the average response time of anonymous users were estimated.By considering the benefits from accessing the cloud service and the time cost on waiting for the cloud service,benefit functions were constructed.Numerical results were carried out to reveal the relationship between Nash equilibrium arrival rate and social optimal arrival rate of anonymous users.The proposed cloud architecture provides a theoretical basis for social optimization.…”

Interference Avoidance and Mitigation Techniques for Hybrid Satellite-Terrestrial Mobile Backhaul System by Xiaoyan ZHANG, He WANG

“…One of the best ways is to assume that satellite and terrestrial segments share the same spectrum in order to utilize more eff ciently the scarce and expensive spectrum resource.The interference avoidance and mitigation technologies such as antenna arrays, multi-antenna communication technologies, intelligent backhaul nodes, interference-aware power allocation method, and licensed shared access (LSA) were deployed in a hybrid satellite-terrestrial mobile backhaul (MBH) system to demonstrated how to enhance the overall capacity of the hybrid system and reuse the spectrum at diff erent systems on a noninterfering basis.Through theoretical analysis and numerical simulations, it is observed that these interference avoidance and mitigation techniques mentioned above could be used eff ciently to meet the enormous capacity demands of future backhaul networks, off -load the terrestrial segment, manage intrasystem (terrestrial) and the intersystem (satellite-terrestrial) co-channel interference (CCI), lead to hardware costs and energy-consumption savings, and improve spectrum utilization eff ciency.…”

A Storage System for Image File in Cloud Computing by Hongfa Wang

“…As cloud computing enters the mainstream，the numbers of virtual machine in one cloud pool is becoming more and more.So，how to quickly and cheaply migrate virtual machines between different hosts for load balance and power savings is becoming one of the hot and tough problems in this filed for the researchers.A distributed storage system was presented，which was called IFSpool.The system was based on Lustre and was designed to achieve the following three goals：high capacity and high extensibility to support thousands of VM images，high I/O throughput for data access，and booting optimization for boot storm.IFSpool combined a queue mechanism and a cache mechanism in a seamless way，to improve I/O throughput and lighten the boot storm by coordinating data access order.The I/O bandwidth and storage capacity of IFSpool can be easily aggregated and extended by adding storage nodes and servers dynamically.The experimental results show that IFSpool is effective and efficient for VM migration.…”

Building method of distributed COW disk on network computing environment by Huai-liang TAN, Zheng LUO, Zai-hong HE, Ren-fa LI

“…Aiming to distributed computing and data centralizing storage in large-scale network computing environments and combining sparse and bursting characteristic of COW(copy-on-write) disk storing modified data blocks,the distributed COW network disk architecture was presented.The system building process of network computing environments was speeded up by apportioning the aggregation spending that server manages all related COW disks of client hosts to each client host.A improving 64bit bitmap compress arithmetic was designed to reduce the size of COW disk’s bitmap,so server disk space was saved and the network communication spending of distributed COW disk was less.The modified prefetching arithmetic based on COW bursting blocks was presented to improve the hit rate of Cache relating with distributed COW disk.Experiments on the prototype show that the distributed COW mechanism can effectively reduce system building latency of multi-client hosts network computing environment based on improving COW bitmap compress and prefetching arithmetic.…”

Energy-efficient optimization strategy based on elastic data migration in big data streaming platform by Yonglin PU, Xiaolong XU, Jiong YU, Ziyang LI, Binglei GUO

“…Focused on the problem that the stream computing platform was suffering from the high energy consumption and low efficiency due to the lack of consideration for energy efficiency in designing process, an energy-efficient optimization strategy based on elastic data migration in big data streaming platform (EEDM-BDSP) was proposed.Firstly, models of the load prediction and the resource judgment were set up, and the load prediction algorithm was designed, which predicted the load tendency and determine node resource occupancy, so as to find nodes of resource overload and redundancy.Secondly, models of the resource constraint and the optimal data migration were set up, and the optimal data migration algorithm was proposed, which data migration for the purpose of improving node resource utilization.Finally, model of the energy consumption was set up to calculate the energy consumption saved by the cluster after data migration.The experimental results show that the EEDM-BDSP changes node resources in the cluster can responded on time, the resource utilization and the energy-efficient are improved.…”

“…In order to address the multi-commodity flow problem for traffic scheduling in software-defined networking,a method based on segment routing was proposed.The proposed method pre-computed sets of candidate paths and attributes of these paths for all source-target nodes,and set the requirements of attributes of candidate paths that should be met combined with various demands and constraints of flows,then generated sets of candidate paths for flows.In the proposed scheme,multi-commodity flow model in software-defined networking was simplified based on sets of candidate paths for flows,the difficulty of solving was reduced,the centralized control by the controller and the autonomous control by nodes were supported,the scalability of controller was improved.In addition,how to meet the energy-saving needs of the network was proposed,i.e.,reducing the number of links that could participate in flow forwarding.The performance evaluation results indicate that the proposed method can meet various demands and constraints of flows,improve network performance,and reduce the computational load of solving the problem of traffic scheduling.…”

Node clustered deployment of emergency Internet of things based on UAV with equipment access restriction by Wei WANG, Yajing LIANG, Li PENG, Zhongcheng WEI, Jijun ZHAO

“…Lack of ground base station in emergency Internet of things for public security application scenarios, the unmanned aerial vehicle (UAV) as the air-based base station was adopted to solve the problem of node cluster deployment under the condition of limited access of emergency Internet of things ground terminal equipment.A clustering deployment method based on on-demand K-means (ODKM) was proposed.Firstly, base station selection and equipment clustering were carried out according to the equipment access ability of different UAV air-based base stations through two clustering steps.Secondly, by solving a relaxed non convex nonlinear optimization model, the UAV air-based base station deployment based on energy efficiency optimization was realized.The experimental results show that the proposed method can meet the constraints of UAV base station access ability, and has a good performance in balancing the transmission energy consumption of each cluster, and realizes the goal of communication energy saving when the ground terminal equipment needs to access.…”
