Routing protocol is the hot problem because of it is the base in self-organized network.

由于Ad Hoc路由协议主要应用在以小电池组为能量来源的移动设备上，能量消耗也是Ad Hoc路由协议性能分析的一个非常重要的方面。

Ad hoc network is a kind of peer to peer network that has special usage. It posses the character of acentric, self-organized, fast deployable and mobile. Because of this, people are paying more attention to the using of Ad hoc network in the emergence area such as battlefield and disaster rescue.

Adhoc网络是一种有特殊用途的对等式网络，具有无中心、自组织、可快速展开、可移动等特点，这些特点使得它在战场、救灾等特殊场合的应用日渐受到人们的重视。

And ourresearch focuses on the following aspects: position based beaconless routingalgorithm, performance comparison of position based and topology based routing,position based and topology based hybrid routing algorithm and routing maintenancealgorithm of DSR by using position information.

本文针对移动ad hoc网络中的路由技术，对移动ad hoc网络中的基于拓扑和基于位置的两大类路由算法和协议进行了总结和分析，集中研究了以下几个方面的内容：基于位置的无信标的路由算法，基于拓扑和基于位置路由算法的性能比较，基于拓扑和位置信息的混合路由算法，以及利用位置信息对动态源路由的路由维护进行改进的算法。

Ant routing use Swarm-Intelligence for route discovery and also have multi-paths for backup and balance. However, the efficiency of ant routing can more and more go down in large-scale mobile ad hoc networks. For solving such condition, improving the efficiency of ant routing, this research proposes the algorithm that combines both the GRID and ant routing, called grid-based ant routing algorithm. GARA can improve efficiency of ant routing in large-scale mobile ad hoc networks.

对於解决路由上的一些问题，也因此有各种不同类别的路由方法被探讨，蚂蚁路由演算法利用群体智慧(swarm-intelligence)找寻路径，而且同时能够找到多条备援路径，但是，蚂蚁路由演算法会因为行动主机数目愈来愈多情况下，而导致路由演算法效率降低，因此本论文以GRID为概念，融入蚂蚁演算法中，让蚂蚁是采用网格对网格(grid-by-grid)方式传输，改善蚂蚁路由演算法在行动主机数目愈来愈多情况下的效率与效能。

Firstly, this thesis introduces background, concept and characteristics of MANET, and points out security issues and challenge through a security requirement analysis for MANET. Secondly introduces the basic concept, classified methods and the composing of the IDS.Basing on the research of the lineate networks, this thesis proposes a hiberarchy model based zone, and presents a new

在针对有线网络入侵检测技术研究基础上提出了适用于无线Ad Hoc网络的基于域多层入侵检测模型，并在该模型基础上实施一种新的混合入侵检测算法；通过NS-2网络模拟仿真器模拟测试了该算法的可行性与有效性，构建了移动Ad Hoc网络与有线网络的互连模型，并提出了适用于该互连模型中的入侵检测实施方案。

To enhance security in Ad-Hoc networks,it is important to evaluate the trustworthiness of other nodes without centralized authorities.In this work,authors focus on the evaluation of trust evidence in Ad Hoc networks.First,the authors introduce the metrics of the trust,the evaluation process is modeled as a path problem on a directed graph,where nodes represent entities,and edges represent trust relations.Using the theory of semirings,a trust evaluation model based on semiring（TD-SEMIRING） is developed,then two nodes can establish an indirect trust relation without previous direct interaction and introduce the application of this model in route election.At last,the feasibility of this model is analyzed.

讨论了对可信事件的评估：首先介绍了可信的相关概念和相关的特性；接着评估过程被建模成一个在有向图寻找最短路径的问题，在该有向图中结点表示实体或者用户，边表示可信关系，通过使用半环理论，建立了一个基于半环的可信性评估模型TD-SEMIRING，在两个以前没有进行相互操作的实体之间建立间接的可信关系，介绍了这个模型在路由选择当中的应用；最后，通过仿真实验，验证、分析了该模型的有效性。
