摘　　要：Ad Hoc网络,又名多跳网、无基础设施网或自组织网,是一种没有核心、独立运作的WiFi。目前,Ad Hoc路由协议的主要种类包括DSDV、WRR、DSR、DODV和TORA等。AODV在Ad Hoc网络里被广泛应用,这是一种根据需求、迅速调整、成本较低并能够实现多次传输的路由算法。Ad Hoc网络遭受的关键安全威胁有被盗听、DoS入侵、“睡眠”攻击、数据伪造、反向传输以及黑客入侵等。本文对Zapata、Hongmei Deng等学者的下游节点验证算法进行详细的阐述,并且提出一种基于反馈ACK的OSAODV算法,该算法能够有效地对抗黑洞的威胁。Ad Hoc network,also known as multi hop network,infrastructure free network,or self-organizing network,is a type of WiFi that operates independently without a core.At present,the main types of Ad Hoc routing protocols include DSDV,WRR,DSR,DODV,and TORA.AODV is widely used in Ad Hoc networks,which is a routing algorithm that can be quickly adjusted according to demand,has low cost,and can achieve multiple transmissions.The key security threats faced by Ad Hoc networks include eavesdropping,DoS intrusion,"sleep"attacks,data forgery,reverse transmission,and hacker intrusion.This article provides a detailed explanation of downstream node validation algorithms by scholars such as Zapata and Hongmei Deng,and proposes an OSAODV algorithm based on feedback ACK,which can effectively combat the threat of black holes.
