在现代工业互联网中,网络的不确定性以及系统时钟的不同步已成为制约网络控制系统性能进一步提升的主要障碍。为了使基于工业互联网的控制系统能够应用于实时性要求较高的工业控制领域,改善网络传输时延和解决时钟同步就成为了关键问题。文章从工业互联网的典型时延问题出发,提出了几种移动边缘计算与雾计算的延时改善方案,探讨了无线网络下引入移动边缘缓存技术和雾计算的优势,利用计算卸载以及多维资源分配,可以在一定程度上优化时延问题。但在实际生产中,很多任务需要在规定的时间内完成,同时还需要考虑到因终端设备的移动以及功率的变化额外产生的传输时延,故局限性较大,因此算法和卸载策略如何建模依然是未来亟待解决的问题。 相似文献

In wireless mobile computing environments, broadcasting is an effective and scalable technique to disseminate information to a massive number of clients, wherein the energy usage and responsiveness are considered major concerns. Existing air indexing schemes for data broadcast have focused on energy efficiency (reducing tuning time) only. On the other hand, existing broadcast scheduling schemes have aimed at reducing access latency through nonflat data broadcast to improve responsiveness only. Not much work has addressed the energy efficiency and responsiveness issues concurrently. In this paper, we propose a fast data access scheme concurrently supporting energy saving protocol that constructs the broadcast channels according to the access frequency of each type of message in order to improve energy efficiency in mobile devices (MDs). The pinwheel scheduling algorithm (PSA) presented in this paper is used to organize all types of messages in the broadcast channel in the most symmetrical distribution in order to reduce both the tuning and access time. The performance of the proposed mechanism is analyzed, and the improvement over existing methods is demonstrated numerically. The results show that the proposed mechanism is capable of improving both the tuning and access time due to the presence of skewness in the access distribution among the disseminated messages.

面向国家“碳达峰”与“碳中和”的“双碳”战略需求,移动通信与网络需要在满足不断增长的业务需求前提下大幅度降低全网能耗,因此需要研究使用更少的能量传递更多信息(SMILE, send more information bits with less energy)的理论与技术。为了应对该挑战,仅靠无线传输技术的改进和硬件实现水平的提高是远远不够的,需要从系统和网络的角度探索能量的高效利用机理与方法。从能量的“节流”和“开源”2个维度展开,并针对日益增长的计算能耗给出解决方案。具体地,通过引入超蜂窝网络架构实现网络的柔性覆盖与弹性接入,使业务基站和边缘服务器在业务量较低时可以进入休眠状态,减少能量的浪费(即“节流”)。同时,大量引入可再生绿色能源(即“开源”),通过能量流与信息流的智能适配,大幅降低电网的能耗。进一步地,通过网络功能虚拟化、通信与计算资源的高能效协同,以及移动智能体的分布式计算与协同等手段,实现绿色计算与人工智能算法。 相似文献

Due to the limitation of node energy resources, the management of energy consumption is one of the most important problems of the internet of things (IoT). Therefore, many studies have tried to optimize and manage energy consumption by focusing on different techniques. Although each of these studies has improved and optimized energy consumption, there are many important problems, including maintaining traffic balance and energy consumption of network nodes. Therefore, a new method is necessary to maintain the load and energy balancing of network nodes. Therefore, this paper introduces energy and load balancing routing protocol for IoT (ELBRP) based on the development of the RPL routing protocol and the efficiency of data distribution technique. The ELBRP performance has three steps. In the first step, along with the process of sending DODAG information object (DIO) messages, the status of network nodes is evaluated. In the second step, the DODAG communication graph is formed according to the ELBRP. In the third step, data transmission is done according to the distribution technique with the goal of balancing traffic and energy. The simulation results using cooja simulator showed the superiority of ELBRP in improving energy consumption and successful delivery ratio, reducing delay and increasing the network lifetime compared to the similar methods. 相似文献
