It is an extreme challenge research subject for such network due to the dynamical topology change, bandwidth limitation and power constraint. the state - of - the - art of the manet technology in 5 layer : physical layer, mac layer protocols, routing protocols, transport protocol and application and middle ware issuses are summarized in this thesis. five typical routing protocols dsdv, dsr, tora, aodv and zrp are studied
本文介紹了移動自組網的起源、特徵和當前的發展狀況，並歸納了其主要的應用領域；分別從物理層、 mac層、路由層、傳輸層、中間件和應用層等5個層次分析和介紹了當前manet採用的技術和協議，尤其對路由協議（ dsdv 、 dsr 、 tora 、 aodv和zrp ）進行了詳細的研究。 -
Time, bandwidth and memory resources are occupied to result in the link block as well as the deluge of unhealthy messages. currently, there are some mature filtering methods which adopt software automated filtering and user setting rules. most of the software has a constraint that they need manual setting, which requires some professional domain knowledge
目前已有一些比較成熟的過濾方法採用通過軟體自動過濾與用戶設定規則的方式，但這類軟體存在著明顯的不足:它需要人工設定過濾規則，這要求用戶或管理員有較強的專業知識，還要求用戶能隨著垃圾郵件情況的變化不斷調整這些規則。 -
The duty of real - time system is to provide time constraint guarantees for the real - time applications, in other words, it make the applications access to the resources they need timely. many works have devoted into individual resource scheduling ( i. e. processor capability, disk bandwidth and network bandwidth ). obtaining simultaneous and timely access to multiple resource is known to be a np - complete problem
大量的研究工作集中在單純的網路帶寬、磁盤帶寬和處理器資源各自的調度優化上，而在同一個節點上同時使用多個資源的是比較復雜np完全問題，本文分析了一種在資源預留系統（ resourcekernel ）中解決該問題的途徑，聯合調度服務器（ css ） ，並對其中的關鍵問題? ?伸縮量分配（ slacksharing ）作出了改進，提出了一種基於當前系統負荷的分配演算法。
