With the increasing scale of the Internet, the problem of network energy consumption is attracting more and more attention. At present, computer network is faced with problems such as high energy consumption, low efficiency and low link utilization. These problems have become a bottleneck restricting the further development of computer network. In this paper, an Internet routing energy saving algorithm based on flow matrix is proposed, which maximizes the utilization of network link and minimizes network energy consumption on the basis of ensuring network efficiency.

Summary With the continuous development and improvement of cloud computing technology, it has been widely used by different operators due to its unique advantages and huge commercial value. However, there are still many shortcomings in system maintenance and management, and the efficiency of energy consumption. It is one of the priorities that need to be addressed. This paper studies the high energy consumption of cloud computing data centers, categorizes the current energy-saving algorithms, and focuses on virtualization-based energy-saving algorithms, DVFS-based energy-saving algorithms, host-based power-off algorithms based on host shutdown/on, and virtual machine migration algorithms. And the energy consumption assessment model of virtual machine migration, and the advantages and disadvantages of the algorithm are briefly explained.

Aiming at saving energy and reducing the maintenance cost and difficulty of the urban street lighting system, this paper proposes a design scheme for an intelligent LED Street light control system based on NB-IoT network. The solution consists of a cloud server, a remote monitoring interface, and street light control terminals. Combined with NB-IoT network and Power Line Carrier (PLC) communication, this solution realizes local intelligent control and remote supervision of LED street lights. During daytime when lights are normally off, if the light intensity sensor detects that the natural brightness is insufficient, lights will be turned on at a required level. During nighttime when lights are normally on, the on-demand lighting is achieved by the energy-saving algorithm described in this paper. Meanwhile, environmental monitoring can be realized as well as fault alarm and abnormal protection.

电脑学刊 2018年第3期29卷 188-196页

作者： Yan-Hong Hu Yu-Hai Li Wen-Qi Xie

It is known to all that Wireless Sensor Networks (WSN) is plagued by the energy shortage caused by the environment factors. In this paper, a novel energy-saving algorithm named COLD is proposed. Which is based on ladder diffusion and comprehensive optimization. In COLD, firstly, ladder diffusion is introduced to decide the sink nodes number. Then, the best nodes will be selected under comprehensive optimization strategy, which residual energy of the node, communication costs and average energy are considered together. Finally, In the routing selection phase, both distance and the difference of the angle will be taken into consideration. A non-uniform clustering was used to deal with ＂hot area＂ problem. Experimental results show that the proposed COLD has better performance than other related routing algorithms in several aspects, such as life cycle, the average residual energy of whole nodes, and energy consumption balance.

Heterogeneous multicore systems have become the trend for the embedded market due to its advantage of power/performance over traditional designs. However, monitoring the workload, scheduling the tasks, and managing the energy consumption to enable energy-efficient, real-time applications are increasingly challenging on such systems as both the applications and systems become complex. In this paper, we introduce a comprehensive approach to address the key problems and accelerate the design of a heterogeneous multicore embedded system by providing a suite of energy-aware system software with tightly coupled real-time support and performance/power modeling facilities. We start with a rapid full system modeling/simulation framework to characterize the application workload, design energy-saving algorithms, and verify if performance requirements are met by hardware specifications during the early design stage. With special considerations on today's multicore embedded systems, we developed several key components and integrated them as a system software suite: a portable, efficient library to support inter-core communications and multicore programming, a lightweight kernel for dynamically monitoring and sharing the workload among the processor cores, and a dynamic voltage and frequency scaling scheme to adjust the setting of the processors to save energy. The system software has been implemented on the PAC Duo system as a case study, with experimental results to demonstrate the effectiveness of the proposed approach. This paper discusses the novel techniques included in this system software and shares the lessons that we have learned from this work.(1)

Robot Positioning and Navigation Based on Hybrid Wireless Sensor Network

Traditional sensor network and robot navigation are based on the map of detecting the fields available in advance. The optimal algorithms are developed to solve the energy saving, the shortest path problems, etc. However, in the practical enviroranent, there are many fields, whose map is difficult to get, and needs to be detected. In this paper a kind of ad-hoc navigation algorithm is explored, which is based on the hybrid sensor network without the prior map in advance. The navigation system is composed of static nodes and dynamic trades. The static nodes monitor the occurrances of the events and broadcast them. In the syston, a kind of algorithm is to locate the rdbot, which is based on duster broadcasting. The dynamic nodes detect the adversary or dangerous fields and broadcast warning messages. The robot gets the message and follows ad-hoc routine to arrive where the events occur. In the whole process, energy saving has been taken into account. The algorithms, which are based on the hybrid sensor network, are given in this paper. The simulation and practical results are also available.
