Path Congestion Control in Centralized Autonomous System

This paper analyzes the importance of a centralized controller based system with congestion over the network. Some previous researches show validity of the centralized controller by experiments [11]. However, the effectiveness has not proved analytically. Therefore, this paper provides an idea for the congestion control over the path instead of over coming it from the congested node. When delay...

Centralized Sliding Mode Control of Power System with UPFC

In this article is proposed a Centralized Sliding Mode Control (CSMC) applied to a UPFC device for controlling power flow and enhancing power system stability. First, we establish a state-space dynamic model of UPFC based on Kirchhoff’s equations and (d-q) transformation. This model includes the two voltage source inverters and the DC bus voltage link. Furthermore, in order to cancel the effect...

Centralized and Distributed Job Scheduling System Simulation at Exascale

Job scheduling systems aim to efficiently manage the distributed computing power of workstations, servers and supercomputers to maximize throughput. As the development of high-speed networking and powerful supercomputers, the scheduling systems should be up to the exascale that is billions of jobs executed by millions of nodes with thousands of cores each, which is however, beyond the state-of-...

Distributed caching with centralized control

The beneets of using caches for reducing traac in backbone trunk links and for improving web access times are well-known. However, there are some known problems with traditional web caching, namely, maintaining freshness of web objects, balancing load among a number of caches and providing protection against cache failure. This paper investigates in detail the advantages and disadvantages of a ...
