查询词典 underlying topology

One of the reasons is that the construction of the peer overlay in existing P2P systems has not considered the underlying physical network topology and can cause serious topology mismatch between the P2P overlay network and the physical network.

其中一个原因是，建设同侪重叠在现有的P2P系统没有考虑到背后的物理网络拓扑，并可以引起严重的拓扑结构不协调的P2P重叠网络和物理网络。

In this paper, we discuss the problem of the P2P (peer-to-peer) networks with mobility. The peer's mobility easily causes topology mismatch between the P2P logical overlay network and physical underlying network. The topology mismatch makes P2P network inefficient.

在这篇论文中，我们首先探讨P2P网路在行动环境所面临的问题。P2P网路在节点具移动性时，节点中的逻辑连结与实体连结容易产生拓朴失配，此将降低P2P网路效能。

In mobile Ad Hoc networks, geographical routing protocol was a kind of important routing protocols, which requires the underlying topology be planar, sparse, connected and t-spanner in order to guarantee the delivery of message and bound the routing length. A new topology control algorithm named ODT, which constructed the geometry structure named ODT graph, was proposed.

基于移动Ad Hoc网络的特性，提出了一种适用于移动Ad Hoc网络的路由协议PAGPSR(Power-Aware Greedy Perimeter Stateless Routing)，该协议在原有的基于地理位置的路由协议GPSR的基础上增加了节点能量感知和负载均衡算法，修改了GPSR的转发策略，使网络中能量消耗和网络负荷分布更加均匀，从而延长了整个网络的生存时间。

This paper models the underlying network topology as an Euclidean space and uses PCA to map this higher dimensional space to the lower dimensional logical space of CAN. So a peer's identifier is determined by its location in underlying network.

以对等网络系统CAN为基础，将底层网络拓扑建模为高维欧氏空间，使用主成分分析法将底层网络拓扑映射到低维CAN逻辑空间，从而根据节点在底层网络中的位置决定其在对等网络中的标识符。

And to the problems of special distribution of underlying assets, this paper analyzes the price movement of the underlying assets from the arrival of information, the market efficiency and the market mechanism which decide the price. It also studies the problem of real option pricing when the underlying assets follow the pure jump Poisson, mixed jump-diffusion Merton and mean-reversion model, and obtains the price formula or partial differential equation to price and hedge the real option.

对实物资产的特殊价值分布问题，本文从决定资产价格的市场机制、信息到达方式及市场效率三方面来分析实物资产的价格变动特征；并重点研究当基本资产遵循纯跳跃Poisson过程、跳跃扩散Merton过程及均值回复过程时的实物期权定价问题，运用复制定价和随机动态规划方法，得到确定实物期权价值和风险对冲策略的偏微分方程。

In chapter 5,we introduce the De Morgan algebra of metric and investigate the pseudo-metric Uniformity and the pseudo-metric topology and the separation axioms in De Morganalgebra of metric.We establish the Baire category theorem and the Banach contraction theo-rem,the Edelstein contraction theorem and other fixed quasi-atom theorems in De Morganalgebra of metric.In final,we give a sufficient condition for the metrization of a De Morganalgebra of topology.
