Distributed security model 这两种模型的主要不同点在于节点入网方式以及如何保护通信的安全性。 集中式网络(Centralized network) 在Centralized 网络下,一个节点(即coordinator)充当集中式密钥分发中心(Centralized trust center),负责整个网络的密钥管理和分发,其决定着其他节点是否可以加入网络,何时可以加入网络,并且在节点...
After that, the interaction between RRM and CRRM entities is discussed. Then, different approaches for the distribution of RRM and CRRM entities among the Core Network (CN), RATs and User Terminals (UTs) will be presented. Finally, a comparison between distributed and centralized algorithms is ...
Network-GIANT: Fully distributed Newton-type optimization via harmonic Hessian consensus This paper considers the problem of distributed multi-agent learning, where the global aim is to minimize a sum of local objective (empirical loss) functions through local optimization and information exchange between...
集中式,分布式,协作式数据处理的区别(The centralized, distributed, collaborative difference data processing) 集中式,分布式,协作式数据处理的区别(The centralized, distributed, collaborative difference data processing) 1) centralized data processing Centralized computer network consists of a large central system,...
Republicans aim to distribute power away from centralized government bureaucracy—big is bad in the '90s. The reverse power play is at work in broadband HFC networks, where service providers move to centralized from distributed network powering. The terms "centralized" and "distributed" powering aren...
The objective of the paper is to identify the strengths and weaknesses associated with Centralized Generation (CG) and Distributed Generation (DG) infrastructure for the futureelectric grid system. There are many reasons for considering the extent to which a planning andoperation decision about CG an...
准确地测量网络的性能是保证网络高性能运行的前提,针对SDN(software-defined networking)的网络架构提出一种集散式网络性能测量方式——CD(centralized-distributed)网络性能测量方式.该方式以集中式的控制模式实现对测量实体的统一化管理,以分布式的测量方式实现对网络流量分散化处理,使SDN能更灵活地调整网络结构,平衡网络流...
Cell-Free Massive MIMO is a distributed Massive MIMO network, consisting of many low-cost, low-energy access points (APs) connected to a Central Control Unit (CCU) via a backhaul network. The number of AP antennas far surpasses the number of users. In CFmM, the network is not divided int...
to a granularity of only enforcing average power constraints per beam. In conjunction with suitable short-term scheduling, our algorithms gradually steer the network towards a higher utility. We use extensive system-level simulations to compare three distributed algorithms and evaluate their applicability...
In addition, the centralized case is extended to a distributed framework for both the estimation and attack problems. Different distributed scenarios are proposed depending on assumptions that lead to the spreading of the resources, network nodes and players. Consequently, for each of the presented ...
