目前,无线通信技术因为其成本低廉、适应性和扩展性好、为设备维护上更容易实现等原因得到广泛应用.近几年,产生了例如蜂窝网络、无线局域网等多种无线网络技术.其中Ad hoc网络因为其不依赖任何固定基础设施的特点得到更为广泛的应用.
本文阐述了Ad hoc网络的基本概念,应用领域,国内外发展情况,以及发展前景.通过与传统的无线网络的比较,分析了Ad hoc网络的优越性及局限性.通过对现有的安全路由技术进行研究,论述Ad hoc网络路由安全的重要性.对Ad hoc网络路由协议进行分类比较,讨论安全路由协议的优点和缺点.重点对AODV路由协议的具体执行过程进行表述,并针对Ad hoc网络中AODV路由协议中受到的黑洞攻击提出一种基于公开密钥体系（PKI）的改进方案,该方案可以在某种程度上可以保证AODV路由协议的安全性.最后对提出的方案进行总结和展望.
关键词:Ad hoc网络；安全路由协议；黑洞攻击；PKI

第一段翻译如下
At present,wireless communication technology cause such as cheap ,coming true more easily on adaptability and the equipment upkeep easy to be expanding nature because of whose cost,gets extensive use.Have produced wireless various networks technology such as for example beehive network ,wireless local area network over the past few years.Ad hoc networks among them are broad application more because of the person is not dependent on any fixed infrastructure construction characteristic.
第二段翻译如下
The main body of a book has been set forth as well as the network Ad hoc basic concept ,the condition applying a field ,developing at home and abroad,developing a prospect.By the wireless network comparison with tradition,have analysed network Ad hoc superiority and limitation.Study by the fact that routing technology is in progress to now available safety ,discuss safe significance of Ad hoc network route.The network route is in progress by agreement to Ad hoc classify and comparing ,discusses safe route agreement merits and demerits.The concrete priority implementation process to AODV route agreement carries out formulation,security joining the guarantee AODV route agreement attacking put forward kind of specifically for the black hole that Ad accepts in hoc network in AODV route agreement being a scheme's turn to be able to be not bad on some species degree owing to making the secret key system (PKI) improvement scheme known to the public.The at last sums up and looks into the distance to the scheme go along suggesting that.
