In order to solve this problem, some scholars presented the idea by utilizing the parallel techniques to provide the large accessible physical memory and by reasonable decomposition the whole problem to every compute node then making all the compute nodes work together to solve the whole problem
為了解決這一矛盾，有學者提出了採用并行技術提供較大的物理內存，並將任務合理地分解，并行計算的方式來解決這一問題。上世紀90年代錫拉丘茲大學（ syracuseuniversity ）首先在這方面做出了嘗試，他們實現了并行矩量法程序。 -

Specifically, for the first time all factors impairing tcp performance are identified based on network protocol hierarchy, i. e., lossy wireless channel at the physical layer ; excessive contention and unfair access at the mac layer ; frail routing protocol at the network layer, the mac layer and the network layer related mobile node ; unfit congestion window size at the transport layer and the transport layer related asymmetric path
Tcp是一種面向連接的可靠傳輸層協議，最初是針對有線網路設計的。由於有線網路鏈路可靠性高，傳統tcp認為丟包和亂序是由網路擁塞所導致。然而，在manets中，眾多非擁塞因素導致了丟包和亂序。 -
The beginning point of the first research direction is that we design a type of load - balancing virtual topology which is insensitive to the traffic, such plan method has been proposed whose name is vlbs ( valiant load - balancing schemem ), the disadvantage of vlbs is that it can only be applied to the homogeneous network in which each node has the same capacity, in chapter2, a more general valiant load - balancing scheme ( gvlbs ) has been proposed, the advantage of the gvlbs is that it can be used both on the homogeneous network and heterogeous network, in this chapter, we will give the detail derivation process and numerical analysis. the beginning point of the second research direction is that we first design a virtual topology for the physical topology under a specific traffic matrix, for a while, the traffic has changed, the network performence will decline. under such condition, in chpater 3, a virtual topology reconfiguration algorithm is studied which can decrease the average weighted hops
本文針對動態變化業務量情況下的wdm網路設計方法劃分為兩個主要的研究方向，第一個方向的研究出發點是可以在最初的虛拓撲設計過程中根據物理拓撲情況設計出一種虛拓撲出來，該虛拓撲是負載均衡的，在這種虛拓撲上跑的業務量矩陣特徵只要在某種范圍以內，無論它怎樣動態變化，網路都不會出現擁塞，但這種虛拓撲設計演算法vlbs的一個缺陷是它只能適用於同構網路，即每個節點所擁有的容量大小都相等，在第二章中，本文提出了一種更通用的負載均衡的光網路虛拓撲設計演算法gvlbs ，該演算法與傳統的負載均衡演算法vlbs不同之處在於vlbs演算法只能適用於同構網路而gvlbs演算法既可以適用於同構網路，又可以適用於異構網路，在本章中將給出了gvlbs演算法的的詳細推導和數值分析。 -
The goal of this thesis is to give a scheme on the application of wireless sensor network system indoor. first of all, we have a deep research on the ‘ telos ’ node, secondly, we build up a stack system structure of wireless sensor network to monitor the temperature of the building intellectively, design and realize the network stack including physical layer, data link layer, network layer and application layer. finally, we debug the software in order to verify the network layer and the application layer
本文以智能樓宇溫度監測應用為設計目標，以em2420射頻晶元和atme128l單片機為設計載體，在詳細研究telos節點方案基礎上，對面向設計目標的室內無線傳感器網路節點的物理層、數據鏈路層、網路層和應用層之間的網路協議棧進行了實現性設計，建立了立足設計目標的無線傳感器網路協議體系，並在avrstudio4 . 11調試環境下對網路層和應用層設計正確性進行了調試驗證。 -
In order to solve this problem, this paper proposes one kind of new topology - aware p2p network routing protocol and constructs its model tabip. it according to territorial continuity of ip address ( public network ip address ), and its node id and object id includes the information of ip address that is organized by country id. it is consistent between the node ’ s proximity of overlay network and physical node ’ s proximity
為了解決這一問題，本文提出一種新的拓撲相關p2p網路路由協議並構建其模型tabip ，它依據公網ip地址分配的區域連續性規律，在生成節點和對象標識符時加入按國家編號組織的ip地址信息，使得覆蓋網上節點的鄰近和實際節點的鄰近趨於一致。 -
