该协议以移动WSN能量优化为目标，采用计算几何数学模型工具构造协议路由图，使得网络节点只需要在本地选择通信邻居并动态调整传输半径，来构造一个全局能量有效的路由拓扑。

The most valuable underlying network topology is the 2DMesh network, which is simple and easy to scale up. In most cases, a certain NoC system is designed for a specific application, which is consisted of many IP cores.

片上网络平台下的系统设计通常是为某一特定应用设计，网络中的并行计算单元为处理核，通过将它们以不同的方法映射至网络节点，将对系统的延时和功耗产生影响。

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。

With the development of Ad Hoc networks, some researchers proposed geometric routing protocols to guarantee the delivery of the packet between any pair of nodes in the network, and the underlying network topology is also constructed by the ways of Delaunay triangulation.

随着无线Ad Hoc网络的发展，一些研究者提出了可以保证网络任意节点对之间分组顺利传输的几何路由协议，而这些协议的网络基础拓扑同样可以用Delaunay三角剖分的思想来实现。

At present DHT faces many problems, the biggest problem is in the initial design DHT overlooked the nodes vicinity in the physics network, resulting in the link between overlap network and physical network is small, that is DHT failed to take full advantage of the underlying physical network topology information.

目前DHT还面临许多问题，最大的问题之一就是DHT在初始设计时忽略了参与节点在物理网络上的邻近性，导致重叠网络和物理网络联系小，即DHT未能充分利用底层物理网络的拓扑信息。

Based on the behavior of user in the P2P networks applications,the model has designed many attributes for every peer;some current strategies of peers selection and pieces selection are included in the model;the model has devised the interface for the underlying overlay network topology architecture.

该模型根据现实P2P资源共享系统中用户的行为的基本特点设计了Peer的各种属性，包容了现有常见的P2P资源共享应用中peers选择和pieces选择策略，并为进一步设计P2P底层覆盖网络拓扑结构提供了接口。

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。

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。

For single-attribute range queries in Armada, this thesis designs the single-attribute order-preserving naming algorithm Single_hash to assign adjoining ObjectIDs to objects with close attribute values based on the partition tree model, so that the objects can be published to the same or related peers in the P2P system. Then this thesis proposes the single-attribute range query processing algorithm PIRA, which can match the search paths of range queries to the underlying FissionE topology efficiently based on the forward routing tree to reduce the delay and message cost of range queries.

为实现Armada单属性区间搜索，本文首先提出基于分区树的单属性维序命名算法Single_hash，使得属性值接近的资源对象能够获得相近的标识，以发布到相同或相关的结点上；然后提出基于前向路由树的单属性区间搜索算法PIRA，实现了区间搜索路径与底层FissionE拓扑的高效匹配，以有效降低区间搜索延迟，减少搜索消息开销。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
